  • [00:01:02] <thurbad> meh.. bad file-roller!!!
  • [00:01:32] <thurbad> it apparently doesn't clean up temp files very well
  • [00:02:09] <Ceriand|work> ds2: on my project at work, I don't have any NAND or NOR, so I thought I'd cut out the u-boot middle man and just a small linux with initramfs as a bootloader
  • [00:02:30] <Ceriand|work> *just have
  • [00:03:19] <Ceriand|work> I also tried to get u-boot to work with just a configuration header, but that wasn't very successful
  • [00:03:59] <DanaG> Ceriand|work: sounds a lot like the "kexecboot" thingy on Angstrom.
  • [00:04:10] <Ceriand|work> yea, that's the idea
  • [00:05:32] <ds2> ah I see
  • [00:05:46] <ds2> Ceriand|work: what about a lighter weight bootloader?

  • [00:08:17] <Ceriand|work> ds2: It's less work just to get linux to work, than linux and u-boot
  • [00:08:30] <Ceriand|work> space on the emmc isn't really an issue
  • [00:10:12] <ds2> nice
  • [00:10:23] <ds2> it might make recovery on a MMC less system less painful
  • [00:10:38] <ds2> since I think xloader can be downloaded pretty easily via serial or USB
  • [00:11:03] <Ceriand|work> true
  • [00:11:04] <DanaG> hmm, it seems it's not possible to have u-boot stick its output on both serial and usbtty.
  • [00:11:16] <jkridner> Ceriand|work: that was pretty fast.
  • [00:11:32] <jkridner> DanaG: I've seen it work.
  • [00:11:46] <Ceriand|work> jkridner: turns out the SRAM in the OMAP isn't mapped in the MMU on early boot
  • [00:12:00] <Ceriand|work> that's where I put my ATAGs
  • [00:12:03] <DanaG> Okay, a different question: is it possible to, at runtime, set the usb-gadget framework to export an audio device, instead of just an ethernet device?
  • [00:12:26] <Ceriand|work> put them in SDRAM and it works like a charm
  • [00:12:54] <ds2> DanaG: if so design, yes
  • [00:13:15] <DanaG> hmm, anyone know how to do so?
  • [00:13:54] <ds2> know how? yes... have done so... probally not
  • [00:16:00] <ds2> all you need to do is advertise a descriptor...respond to the setup and allocate an ISOC and an Interrupt endpoints (if you don't want to overload ep0); then relay data between that and the audio device

  • [00:23:38] <DanaG> or maybe it's g_snd. or something.

  • [01:38:18] <thurbad> again.. is your bin directory in your path
  • [01:39:23] <rcn-ee> Pierre__, use: "make CROSS_COMPILE=/path/to/arm/gcc/bin"
  • [01:39:50] <Pierre__> how can I verify path ?
  • [01:39:59] <thurbad> echo $PATH
  • [01:40:37] <thurbad> then again if you specify the absolute path, you're probably ok
  • [01:40:38] <Pierre__> ok, path to Sourcery is not there
  • [01:41:12] <Pierre__> how can I add path to fix this ?
  • [01:41:27] <Pierre__> where is the file ?
  • [01:41:34] <Pierre__> with $PATH
  • [01:41:43] <thurbad> you're on ubuntu?
  • [01:42:01] <Pierre__> yes, 8.04
  • [01:42:30] <thurbad> export PATH=/path/to/bin:$PATH
  • [01:42:57] <Pierre__> ? no file to open and modify ?
  • [01:43:54] <thurbad> if you want ti to be persistent you should probably put it in ~/.bashrc
  • [01:44:36] <Pierre__> ok
  • [01:45:51] <Pierre__> Is this the correct BIN folder ? ~/CodeSourcery/Sourcery_G++_Lite/bin$
  • [01:46:14] <Pierre__> Because this is the content : arm-none-linux-gnueabi
  • [01:46:40] <Pierre__> etc...
  • [01:46:40] <thurbad> what's inside that folder?
  • [01:47:11] <Pierre__> arm-none-linux-gnueabi, arm-none-linux-gnueabi-ar, arm-none-linux-gnueabi-as etc...
  • [01:47:22] <thurbad> yeah probabbly the right folder then
  • [01:47:24] <Pierre__> doesn't look good to me
  • [01:47:34] <Pierre__> arm-none-linux
  • [01:47:50] <Pierre__> good folder, but wrong software ?
  • [01:47:51] <rcn-ee> Pierre__, it's fine... pass make "CROSS_COMPILE=arm-none-linux-gnueabi-"
  • [01:48:01] <Pierre__> ok
  • [01:48:08] <rcn-ee> (without the ")
  • [01:48:15] <Pierre__> ok
  • [01:48:49] <thurbad> you can also use a Makefile and spcify the cross compile file there

  • [01:51:27] <Pierre__> got this error now : bash: make: command not found
  • [01:51:47] <Pierre__> this has to do with the Sourcery installation
  • [01:52:00] <Pierre__> installation doesnt support bash
  • [01:52:05] <thurbad> ok, have you installed build-essentials under ubuntu
  • [01:52:17] <DanaG> hmm, do they assume /bin/sh is bash?
  • [01:52:42] <thurbad> he may not even have a compiler set up yet
  • [01:53:17] <Pierre__> This is what I had to do : % sudo dpkg-reconfigure -plow dash
  • [01:53:22] <Pierre__> Install as /bin/sh? No
  • [01:53:25] <thurbad> ubuntu ships with minimal dev tools
  • [01:53:32] <mru> bash or dash is irrelevant here
  • [01:53:39] <mru> the error above happens to be from bash
  • [01:53:43] <mru> it's saying it can't find make
  • [01:53:55] <mru> so make is the problem, not bash
  • [01:53:56] <Pierre__> it cannot find ls either
  • [01:54:03] <mru> that's bad
  • [01:54:10] <Pierre__> bash: ls: command not found
  • [01:54:13] <mru> did you mess with PATH?
  • [01:54:15] <thurbad> can't find ls.. then you munged the path
  • [01:54:15] <mru> echo $PATH
  • [01:55:00] <Pierre__> echo $PATH = /home/pl/CodeSourcery/Sourcery_G++_Lite/bin
  • [01:55:29] <DanaG> mmyeah, you trampled on PATH.
  • [01:55:32] <thurbad> when you exported you probably didn't put :$PATH at the end
  • [01:55:48] <thurbad> gotta do that or you lose your current path
  • [01:56:03] <Pierre__> yeap your right, I goofed
  • [01:56:17] <Pierre__> I have to put path to bin
  • [01:56:27] <mru> just open a new terminal
  • [01:56:28] <Pierre__> ok, I learned something :-)
  • [01:56:55] <Pierre__> wow,
  • [01:57:03] <Pierre__> path is ok, in new terminal
  • [01:57:09] <Pierre__> this is black magic
  • [01:57:12] <Pierre__> lol
  • [01:57:12] <mru> no
  • [01:57:28] <Pierre__> youre guru guys
  • [01:57:32] <Pierre__> lol
  • [01:57:33] <mru> environment settings are local to a process and its descendants
  • [01:57:44] <Pierre__> ok
  • [01:57:47] <Pierre__> cool
  • [01:58:06] <ds2> so a trick there is to start another copy of the shell
  • [01:58:08] <theholyduck> when you want to make permanent path settings, add it to your .bashrc or something
  • [01:58:18] <ds2> do what you want and if you mess up, exit and start another one
  • [01:58:34] <theholyduck> ds2, then, when you verify it works, make it permanent
  • [01:58:36] <theholyduck> provided you want it
  • [01:58:41] <mru> unless the messup involved deleting lots of files
  • [01:59:13] * mru recalls the time he accidentally deleted command.com from his dad's pc
  • [01:59:20] <thurbad> lol
  • [01:59:22] <theholyduck> ds2, in some cases, the fresh terminal trick helps when compiling software from source on ubuntu systems, and you cant get the executable to run
  • [01:59:38] <theholyduck> just reopen a shell, and run the command
  • [01:59:42] <mru> well, it taught me about boot disks
  • [01:59:51] <theholyduck> in the old shells it wont update new binaries in path
  • [01:59:55] <theholyduck> for whatever reason
  • [02:00:02] <mru> hash -r
  • [02:00:08] <ds2> theholyduck: matter of perference... a fresh window is same as running a new copy of the shell
  • [02:00:23] <ds2> then again, I am also a C shell user ;)

  • [02:00:46] <theholyduck> mru, i never seem to encounter that problem on debian though
  • [02:00:55] <theholyduck> i always asumed it was some sort of ubuntu thing
  • [02:00:56] <ds2> C shell is fine for interactive use
  • [02:00:57] <theholyduck> and left it at that
  • [02:01:07] <mru> ds2: no, it's not
  • [02:01:17] <thurbad> crap, after all that file juggling still can't play even 1Mbps encoded video
  • [02:01:30] <theholyduck> thurbad, the problem isnt necesarily the bitrate
  • [02:01:53] <Pierre__> this is wath I got with export : bash: export: `/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games=/home/pl/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games': not a valid identifier
  • [02:01:56] <ds2> mru: do expond on that
  • [02:02:06] <mru> thurbad: is the file available somewhere? maybe it's just unusually evil
  • [02:02:10] <theholyduck> Pierre__, i think you just broke $PATH again
  • [02:02:12] <mru> ds2: I don't like it
  • [02:02:19] <mru> to me it's not usable
  • [02:02:19] <ds2> uh ok
  • [02:02:23] <thurbad> same resolution, same codec, lower bitrate plays fine
  • [02:02:34] <theholyduck> thurbad, what codec?
  • [02:03:00] <Pierre__> path is fine
  • [02:03:01] <theholyduck> same resolution and same codec still doesnt mean bitrate is the problem
  • [02:03:14] <theholyduck> Pierre__, well that output indicates you did something silly
  • [02:03:35] <Pierre__> ok, I think I know
  • [02:03:59] <theholyduck> mru, there is a difference between 300kbps h264 and 300kbps h264
  • [02:04:00] <thurbad> mpeg4 using the lavc
  • [02:04:24] <theholyduck> thurbad, ok then, mpeg4-asp isnt really complex enough to be down to anything other than bitrate
  • [02:04:51] <mru> mpeg4-asp _can_ be encoded to be very complex
  • [02:04:51] <theholyduck> but h264 has all sorts of optional options that can make decoding alot slower, irelevant of bitrate
  • [02:04:56] <mru> if you use qpel, gmc, etc
  • [02:05:23] <theholyduck> mru, most of these are on in all asp videos, or make little difference to decoding
  • [02:05:35] <theholyduck> h264 has a much large lists of "optionals"
  • [02:05:42] <theholyduck> that vary from file to file
  • [02:06:04] <Pierre__> ok, got path right, but still get same error:
  • [02:06:27] <thurbad> what if you just type mak then TAB
  • [02:06:32] <Pierre__> make: arm-linux-gcc: Command not found
  • [02:06:38] <thurbad> does it autocomplete?
  • [02:06:48] <theholyduck> thurbad, you could have make without the necesary gcc
  • [02:06:50] <theholyduck> in theory atleast :P
  • [02:06:59] <mru> theholyduck: mpeg4-asp with qpel or gmc isn't that common
  • [02:07:00] <Pierre__> yes, auto complete works for make and works for omap3_bea
  • [02:07:04] <mru> and using _both_ is rare indeed
  • [02:07:34] <theholyduck> mru, well, his problem is most likely just the fact that lavc isnt very optimized to run on arm
  • [02:07:36] <Pierre__> find did find "arm-linux-gcc"
  • [02:07:41] <thurbad> true but doesn't code sourcery install it's own gcc?
  • [02:07:47] <mru> lavc is very well optimised for arm
  • [02:07:55] <Pierre__> dont know
  • [02:07:57] <theholyduck> mru, hmm, i was under the impression the amount of neon was minimal
  • [02:08:04] <mru> but it doesn't have mpeg4 qpel or gmc
  • [02:08:07] <theholyduck> and gcc sucking badly at optimizing for it automatically
  • [02:08:11] <Pierre__> but make invoke "arm-linux-gcc"
  • [02:08:13] <mru> because they're so rare I haven't bothered with it
  • [02:08:22] <mru> there's a _lot_ of neon in lavc
  • [02:08:31] <theholyduck> mru, ok then, i guess i got the wrong impression then
  • [02:08:54] <theholyduck> i never looked at neon in lavc, its just something i overhead somebody saying on ffmpeg irc
  • [02:09:11] <mru> don't believe everything you hear on irc
  • [02:09:15] <theholyduck> seemed pretty logical based on how x264 only recently got any arm support at all
  • [02:09:17] <mru> only the bits I say
  • [02:09:22] <ds2> hahaha
  • [02:09:30] <theholyduck> so i extrapolated from those pieces of data
  • [02:09:33] <theholyduck> apparently badly
  • [02:09:34] <mru> lavc had neon support well before x264
  • [02:09:46] <theholyduck> mru, well i figured, since they ported ffmpegs deblocking code
  • [02:09:50] <mru> we were decoding 720p mpeg4-asm in 2008
  • [02:09:53] <mru> asp
  • [02:10:13] <thurbad> Pierre__, what happens if you type arm-linux-gcc by itself?
  • [02:10:16] <theholyduck> mru, hows ffh264 for neon though?
  • [02:10:27] <mru> terrific
  • [02:10:48] <theholyduck> mru, then realisticly, he shouldnt be having much problems now should he?
  • [02:10:49] <Pierre__> bash: arm-linux-gcc: command not found
  • [02:10:55] <mru> there are more h264 optimisations for neon than for mmx/sse
  • [02:11:00] <Pierre__> look to me I didn't install good package
  • [02:11:20] <thurbad> or your path is still not right
  • [02:11:25] <Pierre__> or it miss a package

  • [02:13:36] <Pierre__> ok, gotta go to bed anyway, I'll check that tomorrow
  • [02:13:48] <Pierre__> thanks all, learned good stuff with you
  • [02:13:49] <mru> thurbad: 30s of the file is enough
  • [02:13:53] <thurbad> yeah I might be able to find something else to encode though and see if I'm still having trouble
  • [02:14:13] <mru> what encoder are you using?
  • [02:14:47] <thurbad> avidemux is the front end, not sure what ti is under the covers
  • [02:15:04] <theholyduck> mencoder i think
  • [02:15:09] <theholyduck> or some custom libav use
  • [02:15:12] <theholyduck> i forgets
  • [02:15:16] <mru> and what settings?
  • [02:15:23] <theholyduck> mru, avidemux doesnt give you much info,
  • [02:15:28] <theholyduck> its more of a "Point and click" gui app
  • [02:15:40] <theholyduck> though, i think it has checkboxes
  • [02:15:50] <theholyduck> for some options, so i guess its viable to find some info
  • [02:15:51] <thurbad> yeah, but it's one of the few that handles video rotation correctly :/
  • [02:16:11] <theholyduck> thurbad, i always use avisynth in wine for my video encoding, atleast in the x86 world
  • [02:16:22] <theholyduck> it performs the fastest and with the best quality
  • [02:16:58] <theholyduck> too bad its a windows only tool, its the most useful tool for doing stuff with video, there ever was invented
  • [02:17:12] <thurbad> I can run it in windows
  • [02:17:25] <theholyduck> thurbad, well its just a video filtering framework
  • [02:17:30] <theholyduck> you still need a encoder of some sort
  • [02:17:41] <theholyduck> its a bit overkill i guess for video rotation
  • [02:18:02] <theholyduck> but for dealing with broken video sources, theres nothing in the world that beats it
  • [02:18:52] <thurbad> what encoder would you suggest then?
  • [02:19:05] <theholyduck> thurbad, whats the use-case?
  • [02:19:19] <theholyduck> as in, web streaming? showing at conventions?
  • [02:19:27] <theholyduck> mobile playback?
  • [02:19:48] <theholyduck> thurbad, in most cases, x264 comes out on top
  • [02:19:56] <mru> thurbad: what resolution is your video?
  • [02:20:18] <thurbad> I've got a huge file originally in quicktime format that needs to be rotated, scaled and cropped into a format that's supported on the beagle
  • [02:20:29] <thurbad> the resolution is 720x480
  • [02:20:31] <theholyduck> the only reasons not to use x264 to make h264, is really hardware compitability
  • [02:20:53] <theholyduck> x264/libx264
  • [02:21:17] <mru> thurbad: for that I'd use x264 with decoder-friendly settings at 1Mbps
  • [02:21:38] <mru> theholyduck: can you elaborate on that?
  • [02:21:52] <thurbad> what setting are 'encoder friendly'?
  • [02:22:14] <mru> --tune fastdecode
  • [02:22:27] <thurbad> cool, thanks
  • [02:22:33] <theholyduck> mru, well, dvd-players that play some form of mpeg4-asp for instance
  • [02:22:56] <mru> well, duh
  • [02:23:14] <theholyduck> mru, on the other hand, i guess more cellphones have h264 asics than support for mpeg4-asp
  • [02:23:37] <mru> the way you phrased it, I got the impression you had cases where using another h264 encoder was advisable
  • [02:23:49] <theholyduck> mru, well naw
  • [02:23:57] <mru> phones tend to have both actually
  • [02:24:08] <theholyduck> x264 out classes and outshines even the best comercial encoders
  • [02:24:19] <theholyduck> performs better at pretty much anything

  • [02:31:43] <mru> depends on volume and pricing
  • [02:31:56] <mru> the price list is available at mpeg-la
  • [02:32:16] <mru> of course, in the free world, it doesn't cost a penny
  • [02:33:24] <theholyduck> thurbad, well, depends on what you do,
  • [02:33:29] <theholyduck> theres no fees for online distrebution
  • [02:33:41] <theholyduck> theres a encoder fee if you distribute more than 100k encoders
  • [02:33:42] <mru> free online distribution
  • [02:33:48] <theholyduck> or run more than 100k encoding servers
  • [02:33:50] <mru> if you charge for the videos, you have to pay
  • [02:33:59] <theholyduck> mru, well yeah
  • [02:34:02] <mru> if you pass some threshold at least
  • [02:34:17] <theholyduck> thurbad, in general, the fee is little to none
  • [02:34:29] <theholyduck> and you usually never pay for the first 100k units
  • [02:34:30] <mru> stupid as the patents are, the h264 licensing is pretty sane
  • [02:34:38] <theholyduck> mru, its very sane and reasonable
  • [02:34:41] <theholyduck> most mpeg-la stuff is
  • [02:34:49] <mru> no, not at all
  • [02:34:54] <mru> mpeg4-asp is totally insane

  • [02:35:09] <mru> h264 you can always afford
  • [02:35:13] <theholyduck> -asp was the only salvagable part
  • [02:35:19] <mru> barely
  • [02:35:35] <theholyduck> mru, well it still beats the crap out of theora
  • [02:35:46] <ds2> mru: always gamble on theora ;)
  • [02:35:47] <mru> mpeg2 does that
  • [02:35:55] <theholyduck> mru, well yeah
  • [02:36:00] <theholyduck> theora is lolbad
  • [02:36:11] <theholyduck> dirac or snow are much higher quality alternatives
  • [02:36:13] <theholyduck> and just as free
  • [02:36:15] <theholyduck> if not more so
  • [02:36:19] <ds2> they claim that version is patent free
  • [02:36:29] <theholyduck> ds2, well, with no audits of any kind
  • [02:36:31] <theholyduck> on the subject
  • [02:36:36] <mru> dirac has a good chance of being patent free
  • [02:36:38] <ds2> "claim"
  • [02:36:46] <theholyduck> theres not a single shred of evidence that theora is patent free
  • [02:36:49] <theholyduck> other than that xiph says it is
  • [02:36:54] <mru> it was designed by the bbc for that sole purpose
  • [02:37:02] <theholyduck> mru, sure, but its still a wavelet codec
  • [02:37:08] <mru> snow otoh is almost certainly patented
  • [02:37:09] <theholyduck> wich still isnt really viable
  • [02:37:34] <ds2> but what's BBC's licensing for outside of BBC use?
  • [02:37:35] <mru> wavelets don't seem to hold many promises
  • [02:37:43] <theholyduck> mru, well they hold many promises
  • [02:37:46] <theholyduck> just not many solutions
  • [02:37:56] <theholyduck> mru, see the jpeg2k problems
  • [02:38:15] <theholyduck> even at higher filesizes, way higher computational cost and all the rest of it
  • [02:38:21] <theholyduck> the images still look worse than jpeg
  • [02:38:29] <theholyduck> go progress
  • [02:38:39] <mru> wavelets have two problems: coding is insanely complex and it looks like shit
  • [02:38:54] <theholyduck> mru, and doing sane motion compensation on it is hard
  • [02:38:55] <theholyduck> with video
  • [02:38:56] <theholyduck> that is
  • [02:39:03] <mru> ds2: I'm not aware of any fees being charged for dirac
  • [02:39:14] <mru> yes, that too
  • [02:39:19] <mru> so it's even worse for video than for stills
  • [02:40:19] <mru> but dirac is a dead end anyway
  • [02:40:41] <mru> bbc stopped development on it
  • [02:40:59] <ds2> why?
  • [02:41:12] <mru> cheaper to license h264
  • [02:41:16] <ds2> oh
  • [02:41:16] <theholyduck> ds2, because they realized that its never going to be able to compete with h264?
  • [02:41:22] <theholyduck> and h264 gear is cheap enough
  • [02:41:34] <theholyduck> not to mention, everyone else is doing it
  • [02:41:39] <mru> they started development when h264 licensing was undecided
  • [02:41:52] <theholyduck> mru, and continued when all h264 decoders were terribad
  • [02:42:01] <theholyduck> err

  • [02:43:36] <Animule> feh, all this fancy shit... i miss laserdiscs and betamax
  • [02:44:16] <theholyduck> ds2, well, all modern and good video encoders/formats are dct
  • [02:44:19] <theholyduck> as far as i know
  • [02:44:24] <theholyduck> h264 especially
  • [02:44:34] <mru> ds2: h264 uses a simpler transform with some dct-like properties
  • [02:44:36] <ds2> so it is all a matter of the windowing function?
  • [02:44:45] <mru> there is no windowing
  • [02:44:48] <mru> that's in audio
  • [02:44:52] <mru> and wavelets
  • [02:44:53] <ds2> mru: what basis function are using?
  • [02:45:01] <mru> not sure
  • [02:45:09] <ds2> I thought you had to window to prevent Gibbs from messing things up?
  • [02:45:24] <ds2> though I donno how ringing in 2D would look like
  • [02:45:36] <mru> like ringing
  • [02:45:44] <mru> as seen in low-bitrate youtube vids
  • [02:45:55] <ds2> as in dark and with bands expanding from the tile?
  • [02:46:35] <mru> mpeg2/4 and h264 encode each block separately
  • [02:46:43] <mru> there is no overlap or windowing of any kind
  • [02:46:51] <mru> there's only the deblocking filter
  • [02:47:11] <ds2> but don't they adjust the values closer to the edge of each tile to cut down on the ringing?
  • [02:47:46] <theholyduck> without deblocking or at low bitrates, the problem is less ringing, more, I CAN SEE THE MACROBLOCKS!
  • [02:47:59] <mru> the quant matrix typically emphasises the more important coeffs

  • [02:48:14] <ds2> Hmm
  • [02:48:20] <mru> theholyduck: actually, what you see is blocks
  • [02:48:32] <mru> an mpeg2/4 macroblock is 2x2 blocks
  • [02:49:19] <emeb1> Whee! Just built a kernel from scratch using mainline omap. Installed & it booted.
  • [02:49:28] <mru> very simply put, the blocks in a macroblock share motion vectors and a few other things, otherwise they're independent
  • [02:49:50] <emeb1> Of course about 1 minute later it aborts journaling and remounts / read-only... :(
  • [02:49:51] <mru> in post-mpeg2 codecs each block can have a separate MV too
  • [02:49:55] <ds2> emeb1: congrats! free of OE at last free.....
  • [02:49:58] <emeb1> but it's a start

  • [12:08:59] <t3ddY> ~1 hour?

  • [12:13:35] <ynezz> t3ddY: but it depends on image you're trying to build

  • [12:14:00] <t3ddY> so no X11 stuff, only the stuff i need
  • [12:14:10] <ynezz> so it depends on your network bandwith
  • [12:14:19] <ynezz> but it should be under 1 hour
  • [12:14:25] <t3ddY> ynezz: that's no issue here :)
  • [12:14:44] <t3ddY> ~100mbit :)

  • [12:15:15] <ynezz> anyway I would be interested with result
  • [12:15:16] <t3ddY> but this is strange, if I build a full bown image with buildroot, it takes me around 20 minutes

  • [13:24:57] <steveh> Hey guys, just trying to figure out which way to go. Native compile on beagle or cross compile? Any thoughts or experiences are appreciated
  • [13:25:41] * flavioribeiro (~flavio@187.64.42.101) has joined #beagle
  • [13:26:30] <adj> native compiling is slow
  • [13:26:42] <mru> cross compile
  • [13:26:53] <theholyduck> adj, well if you got all of eternity
  • [13:26:55] <theholyduck> its fast enough
  • [13:28:16] <adj> for hello world, perhaps
  • [13:28:43] <ynezz> farm of 20 beagles should be fast enough
  • [13:29:12] <mru> it's fast enough if, like debian, you do not care if the sw is obsolete by the time the build is done
  • [13:29:25] <kblin> steveh: I use a native compile for Samba
  • [13:29:39] <av500> kblin: I feel for you
  • [13:29:43] <steveh> anyone try compiling apache?
  • [13:29:51] <kblin> av500: it's fast enough
  • [13:30:06] <theholyduck> mru, what about debian sid?
  • [13:30:15] <theholyduck> mru, sure even sid has delays
  • [13:30:18] <theholyduck> on major stuff
  • [13:30:23] <ynezz> mru: I don't use debian-arm, but ubunutu-karmic doesn't seems obsolete
  • [13:30:25] <kblin> av500: I wouldn't do development on a beagle, but for normal once in a while builds
  • [13:30:25] <theholyduck> but debian sid+experimental then
  • [13:30:36] <theholyduck> ynezz, ubuntu karmic is obsolete
  • [13:30:38] * GPSFan (~kenm@64.92.145.112) has joined #beagle
  • [13:30:45] <theholyduck> ynezz, due to the intresting way ubuntu developement works
  • [13:30:49] <ynezz> oh, really?
  • [13:30:59] <theholyduck> you take a version of debian, either unstable or testing
  • [13:31:00] <theholyduck> depending
  • [13:31:08] <theholyduck> then you freeze it for 2-3 months before launch
  • [13:31:12] <theholyduck> to make it more outdated
  • [13:31:21] <theholyduck> this is after you applied a ton of patches to it
  • [13:31:21] <theholyduck> mind you
  • [13:31:24] <theholyduck> for more "features"
  • [13:31:33] <theholyduck> then, you dont update it for the entire time its released
  • [13:31:51] <theholyduck> so by the end of its run, its atleast 8-9 months out of date
  • [13:32:08] <theholyduck> sure, karmic is early in the cycle
  • [13:32:08] * av500 never updated his win95 to win96...
  • [13:32:11] <theholyduck> but its still outdated
  • [13:32:14] <kblin> theholyduck: so?
  • [13:32:19] * alecrim (~alecrim@189.2.128.130) has joined #beagle
  • [13:32:26] <theholyduck> kblin, its not a major problem
  • [13:32:34] <kblin> theholyduck: at work, we run entrerprose releases on our servers
  • [13:32:35] <theholyduck> i'm just commenting on how ubuntu releases are outdated on release
  • [13:32:47] <kblin> they're so out of date that even debian looks brand new :)
  • [13:32:57] <theholyduck> kblin, theres debian stable
  • [13:33:00] <theholyduck> and theres debian sid
  • [13:33:03] <theholyduck> and testing for that sake :P
  • [13:33:08] <theholyduck> kblin, only stable is lolold
  • [13:33:19] <theholyduck> testing is reasonably well updated most of the time
  • [13:33:20] <kblin> sure, but even debian stable these days is only 2-3 years old
  • [13:33:34] <mru> old != stable
  • [13:33:36] <ogra> theholyduck, how do you define outdated vs unstable and buggy then ?
  • [13:33:46] <theholyduck> ogra, unstable isnt really unstable
  • [13:33:48] <theholyduck> or buggy
  • [13:34:02] <mru> do they really think bugs will evaporate over time?
  • [13:34:03] <ogra> the snapshots ubuntu takes from debian sid are often very broken
  • [13:34:10] <kblin> ogra: theholyduck seems to use a distro where they can do QA in zero time
  • [13:34:19] <theholyduck> kblin, naw, qa is overrated
  • [13:34:20] <theholyduck> :P
  • [13:34:20] <ogra> you really need these 3 months of stabilzation
  • [13:34:31] <theholyduck> ogra, i've been running sid for,,,,
  • [13:34:37] <theholyduck> 4 years now?
  • [13:34:44] <theholyduck> sure theres the occational small breakage
  • [13:34:46] <ogra> theholyduck, would you giv it to your mother ?
  • [13:34:50] <ogra> *give
  • [13:34:51] <theholyduck> but nothing 3 minutes in apt cant fix
  • [13:35:09] <theholyduck> ogra, well no, but i wouldnt give my mother a computer either
  • [13:35:15] <theholyduck> no matter what it ran
  • [13:35:20] <kblin> theholyduck: for that matter, even distros where you continually rebuild your whole system are partly out of date
  • [13:35:31] <theholyduck> kblin, well sure, even sid has qa
  • [13:35:43] <theholyduck> they dont comit major stuff bound to break things at once
  • [13:35:53] <theholyduck> that goes to experimental
  • [13:35:57] <ogra> sure debian does
  • [13:36:10] <theholyduck> then once they figure out the kinks in experimental, it goes to sid
  • [13:36:10] <ogra> experimental doesnt catch all breakage
  • [13:36:16] <theholyduck> ogra, but it does catch alot
  • [13:36:19] <ogra> sure
  • [13:36:29] <ogra> but you often still have major bugs left
  • [13:36:32] <kblin> theholyduck: the samba ebuild included in gentoo is older than the one current debian stable ships, iirc :)
  • [13:36:45] <mru> and then they patch openssl...
  • [13:36:48] <theholyduck> kblin, well gentoo's maintainers are all useless
  • [13:37:03] <theholyduck> kblin, as in literally, i've never met a group of more useless and unfriendly maintainers
  • [13:37:19] <kblin> theholyduck: I've had mixed experience, but I see your point
  • [13:37:25] <mru> I disagree
  • [13:37:37] <av500> /join #distrowars
  • [13:37:39] <av500> oops
  • [13:37:45] <kblin> av500: you're already in there
  • [13:37:56] <theholyduck> i dont really care about the distro, more the people who run it
  • [13:38:01] <av500> yes it is a redirect
  • [13:38:02] <theholyduck> as in, the people who maintains packages
  • [13:38:03] <mru> the gentoo guys I've met were all friendly
  • [13:38:11] <av500> one has a shotgun
  • [13:38:18] <theholyduck> mru, well, gentoo users are mostly just silly,
  • [13:38:23] * ogra agrees with mru
  • [13:38:24] <theholyduck> they arent offensivly bad :P

  • [13:43:21] <kblin> so while we're talking cross-builds, the one thing that tripped me in favour of using native builds was the samba4 build, which for me kept finding the host's python instead of the target's python
  • [13:43:47] <steveh> kblin: I might try native first before I dive into crossbuilds. Maybe a simple "hello cruel world" or something
  • [13:43:47] <kblin> is there any reasonable way to deal with builds that need a wild mixture of host and target tools to build?

  • [15:01:46] <Ulfalizer> av500: the speed should be right (115200)

  • [16:27:34] <prpplague> we are have a pre-production run of the ShowDog, but there is plenty of variations to deal with
  • [16:27:42] <prpplague> StevenC: something specific you are looking to do?
  • [16:28:05] <StevenC> depends on what has already been done, ofcourse :)
  • [16:29:18] <StevenC> (haven't run into ShowDog as part of my quest for information the past two days, I'll google it in a moment)
  • [16:29:35] <prpplague> StevenC: no real info out there as of yet
  • [16:30:15] <prpplague> StevenC: basically just a lcd board that support either a 800x480 or 480x272 tft lcd with 4 wire resistive touch screen, using the tsc2007 ts controller
  • [16:30:36] <StevenC> that's a TI part, I presume?
  • [16:30:41] <prpplague> StevenC: the format of the board and the variations of hardware input/output features has been the biggest challenege
  • [16:31:17] <prpplague> yea
  • [16:32:04] * rsv (~3b6100ff@gateway/web/freenode/x-kejkpbwsjymajpdm) Quit (Ping timeout: 252 seconds)
  • [16:32:31] <StevenC> variations of hardware I/O as in how many other feaures to include on the board?
  • [16:32:49] * bearsh|work (~quassel@inst-232.190.zhaw.ch) Quit (Read error: Connection reset by peer)
  • [16:33:17] * DesktopMa (~DesktopMa@hybellovas250.grm.hia.no) has joined #beagle
  • [16:33:18] <prpplague> StevenC: yea, thinks like LED's, buttons, analog inputs(i.e. joysticks), accelerometers
  • [16:34:18] <StevenC> so it's more in the direction of some gaming/handheld expansion?

  • [16:38:04] <prpplague> StevenC: not enough feedback from potential customers
  • [16:38:41] * robtow (~rob@12.156.66.34) Quit (Ping timeout: 246 seconds)
  • [16:38:42] <StevenC> oh, i see...
  • [16:40:05] <StevenC> well, one can make a "connection board" with addable modules ofcourse, but there's also a limit on how far you can modularize a project...
  • [16:40:44] <av500> the ultimate module is a tiny SMT resistor :)
  • [16:40:54] <ds2> morning
  • [16:40:59] <ds2> jkridner: pong
  • [16:41:20] <StevenC> av500: in terms of user friendliness ofcourse :)
  • [16:41:42] <av500> StevenC: yes, and in terms of users/module in the end
  • [16:42:14] <av500> so far I dont see the critical mass on a huge number of potential modules for the BB
  • [16:43:02] <ds2> is there really a need? the 0.1" headers makes it really really easy to make your own as needed
  • [16:44:52] * zatalian (~zatalian@78-22-179-3.access.telenet.be) Quit (Quit: leaving)
  • [16:46:03] <emeb> 0.1" headers are virtually universal. Now trying to work with mini2440 board & all its I/O is 2mm - harder to find.
  • [16:46:19] * bkero (~freenode@osuosl/staff/bkero) Quit (Ping timeout: 245 seconds)
  • [16:46:29] <StevenC> ds2: true, but I'm inclined to think that there still is a separation between hardware and software guys in the embedded world
  • [16:46:38] <jkridner> hi ds2: was just trying to make the StevenC connection.
  • [16:46:43] <StevenC> please do correct me if I'm wrong
  • [16:46:54] * filip (~filip@filip.math.uni.lodz.pl) has joined #beagle
  • [16:47:01] <ds2> StevenC: that will always be there
  • [16:47:09] <jkridner> I think there is a group of people that represent the cross-over.
  • [16:47:19] <jkridner> who know enough of each to be dangerous.
  • [16:47:26] <ds2> education is the best way to bridge the gap
  • [16:47:51] <ds2> the 0.1" headers is the best feature that makes the BB better then the other boards
  • [16:47:52] <jkridner> trying to divide the two cleanly is a recipe for disaster.
  • [16:48:07] <StevenC> true, that's why I have all those software classes in my EE education
  • [16:48:11] <ds2> you can go down to ratshack and buy most of what you need for a proto at 8PM
  • [16:48:36] <StevenC> not at this side of the world, mind you
  • [16:48:45] <ds2> StevenC: where are you?
  • [16:48:49] <StevenC> (for all clarity, I'm from Belgium)
  • [16:49:06] <ds2> isn't there a equiv of Maplin or Tandy there?
  • [16:49:10] <mru> StevenC: most of the best programmers I know have an EE education
  • [16:49:36] <mru> ds2: maplin ain't what it used to be
  • [16:49:38] <StevenC> it's because we get to see the connection between soft- and hardware, I think
  • [16:49:40] <ds2> StevenC: I'm on the EE side myself
  • [16:49:47] <ds2> mru: neither is ratshack out here
  • [16:50:06] <StevenC> ds2: if you mean a kind of warehouse for electric/electronic components, no there isn't
  • [16:50:21] <ds2> StevenC: oh :(

  • [16:50:37] <emeb> jkridner: 100% yes
  • [16:50:38] <ds2> there's frys in the DFW area?
  • [16:50:48] <jkridner> there is in Houston.
  • [16:50:51] <mru> they're mainly a distributor but will sell single items
  • [16:50:51] <StevenC> there's just your average geek-owned local shop, which stocks almost nothing and is open lik 4 days on 7 and than from 10am to 5pm
  • [16:50:55] <jkridner> I think there is one in DFW area as well.
  • [16:50:56] <mru> and they stock _everything_
  • [16:51:03] <ds2> ah... I get you and gerald's location confused, sorry
  • [16:51:07] <muriani> jkridner: EPO?
  • [16:51:13] <emeb> when you can't buy basic electronic parts within 15 min drive - that's the decline of civilization. :)
  • [16:51:14] <jkridner> EPO!!!
  • [16:51:19] <muriani> :D
  • [16:51:27] <ds2> mru: for mail order there is the UK branch of Newark...Farnell I think is the local name
  • [16:51:28] <jacques> thre is a fry's in DFW area indeed
  • [16:51:31] * jkridner doesn't visit EPO nearly as often now that we have 3 Fry's.

  • [16:51:55] <StevenC> yeah sure, there is Farnell, there is RS Components, there is Digikey and Mouser you can order from
  • [16:51:56] <mru> ds2: mail order for a handful of smt resistors is silly...
  • [16:52:03] <jacques> jkridner: which fry's do you go to? I go to the one on 59S
  • [16:52:03] <muriani> I work about 5 minutes from the fondren location, occasionally work will send me over if we need something weird
  • [16:52:15] <muriani> building our own connector for something, etc
  • [16:52:17] <ds2> mru: with 0.1" and lower speed signals, use stock 5% through holes
  • [16:52:20] <prpplague> StevenC: yea, the real key to a successful board design is making sure you define your goals and target properly
  • [16:52:27] <ds2> even in the US, a good local SMT store is rare
  • [16:52:30] * jkridner begins to reminisce of bicycle rides to ratshack and Ace Electronics, and the semi-annual EPO car ride from the folks.
  • [16:52:30] <muriani> I usually go to the 59S one too
  • [16:52:46] <muriani> although the north location is gonna be closer, soo.
  • [16:52:47] <muriani> *soon
  • [16:52:49] * jacques is in sugar land so it's by far the most convenient
  • [16:52:51] <jkridner> jacques: yup. right next to the office. :)
  • [16:52:57] <mru> ds2: if you need to repair a damaged board with smt components you don't have much choice
  • [16:53:01] <emeb> StevenC: sounds like you're asking for prpplague's trainer board.
  • [16:53:18] <StevenC> trainer board?
  • [16:53:20] <jkridner> although I'm rarely at the office. :)
  • [16:53:31] <muriani> heh
  • [16:53:32] <ds2> mru: unless they are like 0402 or smaller or in a critical signal path, you can jam a through hole on there

  • [17:00:42] <mru> ds2: I don't speak french or dutch, yet survived unscathed in brussels
  • [17:01:33] <StevenC> mru: that is because almost everyone in brussels knows how to speak english :)
  • [17:02:40] <ds2> mru: The train station attendant didn't speak enough english but this was out to waterloo... I got lucky when another group there (probally from the UK) figured it out

  • [17:03:39] <StevenC> don't worry, I can get confused sometimes too :)
  • [17:03:45] <ds2> at least i figured out rue == street, nord = North and oest is east :)
  • [17:03:51] <mru> and I read dutch well enough to make sense of it
  • [17:04:22] <ds2> the first day was confusing... like wtf are every street named Rue ;)
  • [17:04:31] <StevenC> :D
  • [17:04:54] <mru> in brussels there are a few confusing streets with totally different names in dutch and french
  • [17:05:05] <ds2> StevenC: this was walking around downtown (I think,the area had a Virgin store)
  • [17:05:09] <mru> rue midi == zuidstraat iirc
  • [17:05:20] <av500> zuid = south?

  • [17:05:25] <StevenC> jup
  • [17:05:38] <StevenC> gare du midi = brussel zuid
  • [17:05:56] <mru> I knew that, so I figured it was the same street

  • [17:06:05] <av500> gare du midi
  • [17:06:50] <ds2> the nice thing about staying near the airport is... just look for the train that says 'aeroport' and ignore the "misspelling" :D

  • [17:10:23] <StevenC> XorA: depends on where you're coming from
  • [17:11:03] <StevenC> :D you're reminding me of some scenes from 'Allo 'Allo
  • [17:11:24] <ds2> StevenC: one other comment... if you want to be adventurous, you can try to make a TSC from a MSP430 for more educational experience
  • [17:11:55] <StevenC> with tsc being a touchscreen controller?
  • [17:11:55] <mru> ds2: the french/english overlap is larger
  • [17:12:17] <ds2> the target board from the ez430 (MSP430F2013) might be enough to let you avoid some SMT PCB layout
  • [17:12:17] <mru> than the spanish
  • [17:12:21] <ds2> StevenC: yes

  • [17:20:02] <av500> _silentAssassin: on linux
  • [17:20:13] <_silentAssassin> desktop ???
  • [17:20:17] <av500> for a start
  • [17:20:42] <_silentAssassin> ohk !! so i can port is as a stand alone emulator .... does that count ??
  • [17:20:48] <ds2> wonder if you can leverage one of the free JVMs
  • [17:20:54] <av500> no, that is already done
  • [17:20:57] <_silentAssassin> ohk
  • [17:21:13] <av500> android sdk comes with emu for PC, but it emulates a full arm device
  • [17:21:28] <av500> and in the emu, android is the OS, not an app
  • [17:21:54] <_silentAssassin> ohk !!
  • [17:22:12] <ds2> bbl
  • [17:22:32] <mru> just rip out the android userspace and drop it in a container of some sort
  • [17:22:35] <av500> but converting an OS into an app is a huge task
  • [17:22:46] <muriani> I'm pretty sure the idea is for android to essentially run natively
  • [17:22:47] <av500> mru: run it in a vm...
  • [17:22:51] <mru> and replace whatever graphics it's doing with something like xnest
  • [17:22:59] <av500> mru: that is the easy part
  • [17:23:00] <_silentAssassin> yes .... i understand that !!
  • [17:23:00] <mru> no need for a vm
  • [17:23:03] <muriani> chroot the userland
  • [17:23:29] <av500> the hard part is to get rid of stuff like binder
  • [17:23:37] <av500> if you assume to run on a non android kernel
  • [17:23:46] <mru> what does binder do?
  • [17:23:50] <av500> ipc
  • [17:23:52] <av500> and ashmem

  • [17:24:30] <av500> mru: yes
  • [17:24:32] <av500> of course
  • [17:24:33] <mru> wtf?
  • [17:24:46] <mru> sysv and posix ipc not good enough?

  • [17:28:29] <muriani> I had a 333MHz Celeron running Be as an audio workstation
  • [17:28:35] <muriani> oh, I had full color
  • [17:28:52] <muriani> black and white was safe video mode for unsupported cards.
  • [17:29:09] <muriani> he could have used the VESA extension and fixed that
  • [17:29:16] <muriani> at CPU cost, but still
  • [17:29:34] <muriani> and the support's been extended quite a bit now as well.
  • [17:29:57] <muriani> It wasn't multi-user at all though.

  • [18:39:17] <pl> hi all
  • [18:39:50] <pl> anybody knows if UART2 (on J5) is enable on Beagle board ?
  • [18:40:46] <pl> I have not succedded to make it works yet.
  • [18:41:16] <pl> Looking at UBoot source code, it seams that UBoot enable UART2
  • [18:41:30] <pl> (beagle.h)
  • [18:41:56] <pl> but doesn't work on my Beagle
  • [18:42:14] <Ceriand|work> I don't believe UART2 is used as the default console in u-boot
  • [18:42:34] <Ceriand|work> I think it's fixed on UART3
  • [18:42:45] <pl> I want to use it to connect GPRS modem
  • [18:43:00] <pl> with hardware flow control
  • [18:43:16] <Ceriand|work> in u-boot?
  • [18:43:27] <pl> no, with Debian
  • [18:43:56] <pl> But looking at device under Debian tells me there are no tty device for UART2
  • [18:44:13] <Ceriand|work> what does your initial dmesg say?
  • [18:44:17] <pl> So I was wandering maybe UBoot was not configuring correctly
  • [18:44:50] <Ceriand|work> does dmesg have a line that says "serial8250.1: ttyS1 at MMIO 0x4806c000 (irq = 73) is a ST16654"?
  • [18:45:26] <pl> ok let me boot my beagle
  • [18:45:29] * bobbens (bobbens@saw4ever.de) has joined #beagle
  • [18:45:30] <pl> I,ll check
  • [18:45:34] <bobbens> hello
  • [18:46:11] <StevenC> ds2: Thanks for the offer! In the event that I get selected, would you also be interested in mentoring me?
  • [18:47:04] <StevenC> (I'm however not sure that the hardware would be a problem... I'm def. more of a hardware guy)
  • [18:48:58] <pl> beagle doesn't, boot, may take more time then expected
  • [18:55:26] * muriani is waiting for an email from TI for the SGX drivers
  • [18:56:09] <DanaG> heh, "you may not use [the device] for chemical, biological, or nuclear weaponry".
  • [18:56:23] <DanaG> What, do people try to stick beagleboards in missiles? =??
  • [18:56:38] <muriani> they could.
  • [18:56:43] <dm8tbr> ssshhhhh, nobody's supposed to know!
  • [18:56:49] <Ceriand|work> doesn't say anything about conventional missles
  • [18:56:55] <muriani> it's against the terms of use, though.
  • [18:58:07] <bobbens> you'd think one wouldn't care much about terms of usage if developing nuclear weaponry
  • [18:58:34] <cwillu_at_work> I just move up a notch
  • [18:58:40] * cwillu_at_work develops quantum weaponry
  • [18:58:40] <bobbens> "and all I need for my nuclear warhead to dominate the world is a beagleboard... oh damn! I can't use it..."
  • [18:59:03] <cwillu_at_work> all your amplitude are belong to ME
  • [18:59:28] <Ceriand|work> though the beagle would be interesting as a UAV controller
  • [18:59:43] <bobbens> cwillu_at_work: quantum missile suddenly becomes a wave and goes through target?
  • [19:00:06] <dm8tbr> it's the heisen-missile!
  • [19:00:07] <bobbens> Ceriand|work: not sure if beagleboard is best, I'd prefer a beagleboard derived with bluetooth+wifi built in
  • [19:00:14] <DanaG> hmm, how about "planet buster" missile?
  • [19:00:34] <DanaG> oh yeah, it turns out, the only place you can get class-A bluetooth is on USB, not on sdio.
  • [19:00:48] <DanaG> or, you go with bluegiga and pay oodles of money.
  • [19:00:49] <cwillu_at_work> bobbens, you fail quantum mechanics
  • [19:00:57] <bobbens> cwillu_at_work: I do :)

  • [19:01:50] <DanaG> Had nearly infinite range of movement (something like 25 or 30 cells, where a car had only 5 or so).
  • [19:02:14] * cwillu_at_work destructively interferes with DanaG
  • [19:02:25] <DanaG> And then there were "monopole magnet" tubes that divided movement cost by a large amount -- gave any unit "essentially infinite" range along tubes.
  • [19:02:40] <bobbens> space elevator + drop troops
  • [19:02:43] <bobbens> couldn't they move anywhere?
  • [19:02:45] <DanaG> What I did: put a gravship on tubes that loop around the pole of the world. Within one turn, it went around the world about 20 times.

  • [19:21:22] <pl> the file itself ?
  • [19:21:27] <pl> yes
  • [19:21:45] <thurbad> I think it's in u-boot.bin itself
  • [19:22:00] <jkridner> it is, but it has been removed from the latest version of u-boot.
  • [19:22:09] <jkridner> it caused a slight delay in boot.
  • [19:22:26] <jkridner> instead, an orange screen is just given now.
  • [19:22:32] <pl> Ok, but If I want to recompile UBoot and have my own splash screen ?

  • [20:31:52] <Ceriand|work> if you look at the schematic the pins for MCBSP3 are the ones that goto the expansion connector not the the UART2 pins

  • [20:41:18] <Ceriand|work> The CP(UART2_RX) line must stay M4 if you want USB to work correctly

  • [20:53:58] <pl> Ceriand|work: I'm not following you :-(
  • [20:54:27] <Ceriand|work> pl: you know that the pins on the OMAP can be used for multiple purposes, right?
  • [20:54:36] <pl> Ceriand|work: yes
  • [20:54:45] <pl> Ceriand|work: yes, at least some of them
  • [20:55:11] <Ceriand|work> pl: you also know that for many units in the OMAP, they can be mapped to multiple pins as well?
  • [20:55:37] <pl> Ceriand|work: that I don't know
  • [20:56:02] <pl> Ceriand|work: you mean I can map a units (ex: UART) to other pin ?
  • [20:56:13] <Ceriand|work> ie. for UART2 it can be on pins AB26-25,AA25,AD25 and/or AF6,AE6,AF5,AE5
  • [20:56:34] <pl> Ceriand|work: ok, that I didn't know
  • [20:56:35] <Ceriand|work> you can mix them however you want
  • [20:57:20] <pl> ok
  • [20:57:28] <Ceriand|work> since AD25 is being used as a reset signal for the USB PHY, we can use one of the pins in the other set as UART2_RX
  • [20:57:46] <Ceriand|work> AE5 in this instance
  • [20:57:52] <pl> Ceriand|work: ok
  • [20:58:32] <Ceriand|work> the register that controls the pinmux for AE5 is named CS(MCBSP3_FSX) in the u-boot header
  • [20:59:57] <Ceriand|work> all of the pinmux register names are named after their primary, mode 0 function

  • [21:01:12] <pl> Ceriand|work: it is,
  • [21:01:43] <Ceriand|work> it would have been better if they named the registers after the pin name instead of the function
  • [21:02:05] <Ceriand|work> of course the pin name changes with different packages, so I can understand why they did it that way
  • [21:03:53] <pl> Ceriand|work: What UI understand is, omap offer flexibility
  • [21:04:19] <pl> Ceriand|work: Can we have RTS and CTS on UART3 (the one on P9?)
  • [21:05:35] <Ceriand|work> pl: no, because those pins aren't brought out from the omap
  • [21:08:20] <pl> Ceriand|work: ok, I have to stick with UART2, but I have to mux UART2_TX signal on an other pin, thats right ?
  • [21:09:02] <Ceriand|work> UART2_RX is the one you have to have on another pin

  • [21:09:54] <pl> Ceriand|work: sorry, yes
  • [21:11:03] <pl> ok, can we MUX UART2 RX and TX on P9 instead off UART3 ? and have RTS and CTS available ? (this would reduce glue logic)
  • [21:11:57] <Ceriand|work> P9?

  • [21:13:14] <prpplague> muriani: probably
  • [21:13:29] <muriani> PuffTheMagic: cheaper than openpandora.

  • [21:13:50] <pl> Ceriand|work: connector P9,
  • [21:13:58] <muriani> that was for prpplague, I didn't pay attention to tabocmplete, sorry Puff.
  • [21:14:15] <pl> Ceriand|work: connector P9, schematic page 9
  • [21:14:16] <muriani> prpplague: for me, sweet spot price would be $200-250 maybe?
  • [21:14:42] <Ceriand|work> pl: no you can't do that unless you're willing/able to cut some traces
  • [21:14:44] <muriani> I know people that would berate me for spending that much for it, but still.
  • [21:15:22] <Ceriand|work> pl: and you'd no longer have a UART3

  • [21:16:31] <Ceriand|work> pl: section 7.4.4 in the TI TRM
  • [21:17:17] <muriani> prpplague: for example, I'm seriously lusting after a Nokia N900.
  • [21:17:46] <muriani> 320x240 res screen is kinda small though, I've a zipit2 and it's pretty limiting.
  • [21:18:41] <jacques> I would buy an OMAP netbook
  • [21:19:17] * Ceriand|work likes his n900
  • [21:19:57] <muriani> alright, I think the consensus is: OMAP "netbook" = win.
  • [21:19:58] <prpplague> yea the screen is small, but overall cost of the device would be pretty small, i.e. $199-$220
  • [21:20:05] <muriani> yeah
  • [21:20:19] <noway> i have a only a zimage so i can't have the Uimage what to do ,(i 'm using the u-boot)?
  • [21:20:29] <muriani> still, with small screen, you could have pretty smooth UI, even with raw framebuffer
  • [21:20:42] <Ceriand|work> noway: use mkimage to make a uImage from the zImage
  • [21:20:53] <muriani> throw Illume or something on it
  • [21:20:57] <muriani> hmmm, illume
  • [21:21:02] <muriani> I haven't looked at that in ages
  • [21:21:21] <noway> Ceriand|work: YOU MEAN make uIMAGE
  • [21:21:32] <noway> ?
  • [21:22:02] <Ceriand|work> noway: you could do that if you have the kernel source
  • [21:22:03] <prpplague> muriani: it definetly would include 802.11b/g and bt
  • [21:22:10] <prpplague> muriani: that add anything to the mix?
  • [21:22:11] <Ceriand|work> noway: either way you'll have to have mkimage installed
  • [21:22:15] <muriani> that'd be sweet
