  • [02:17:02] <emeb> lotsa folks using opencv on BB - I think there's even a GSoC project for that.
  • [02:18:44] <ghoti> What's the method for telling my C3 to boot the SD card, so I don't have to hold the USER button at each power-on? I recall someone saying last week that "set bootargs" was obsolete.
  • [02:18:56] <ghoti> aditya_1010: I'm working on some opencv stuff now.
  • [02:19:04] <ghoti> aditya_1010: it's s.l.o.w.
  • [02:19:32] <emeb> ghoti: what happens when you don't hold USER?
  • [02:19:45] <ghoti> I think it tries to boot from NAND.
  • [02:20:06] <emeb> did you clear the env vars in NAND?
  • [02:20:24] <ghoti> I don't know. I don't recall reading anything that mentioned that...
  • [02:20:30] <ghoti> So ... probably not. :)
  • [02:20:46] <emeb> do you know what version of MLO & u-boot you've got in NAND?

  • [02:21:51] <emeb> That's good.
  • [02:22:05] <ghoti> yay?
  • [02:22:45] <emeb> pretty recent. Should be doing the right thing if the env vars are cleared & it uses defaults.
  • [02:23:35] <ghoti> Which leads me to two questions. What is "the right thing", and how do I clear env vars?

  • [02:36:22] <ghoti> emeb, there's A LOT of information on that page... It seems that all I really want to do is make sure that nothing in the boot order before the SD card includes anything that may be mistaken for being bootable. I've already got a working Angstrom install - I just don't want to have to hold the USER button to boot it.
  • [02:36:48] <ghoti> Is it safe to do a "nand erase" if I don't think I've installed anything on it?
  • [02:36:51] <emeb> ghoti: (07:28:43 PM) emeb: under the heading NetInstall Method / Troubleshooting

  • [02:38:00] <djlewis> People! quit mucking with uboot #($&%&&%$!
  • [02:38:18] <ds2> =)
  • [02:38:21] <ds2> the factory one is just fine.
  • [02:38:25] <emeb> ds2: but they have to in order to get their GPIO setup right. :P
  • [02:39:11] <ds2> use the kernel one
  • [02:39:13] <ds2> it works.
  • [02:39:16] <ghoti> emeb, the instructions from that page for clearing environment variables haven't helped me, and I don't see anything else there besides instructions on upgrading u-boot (which I don't need) and installing Ubuntu (which I don't want).
  • [02:39:54] <djlewis> ghoti: what is your error msg without user button?
  • [02:40:05] <emeb> ghoti: only other thing I can recommend is using koen's boot.scr that sets up NAND
  • [02:40:10] <ghoti> No error message. I just don't see anything after "I2C: ready".
  • [02:40:16] <emeb> but I don't remember where it is
  • [02:40:37] <djlewis> it sounds like you need a newer MLO and uboot in flash
  • [02:40:45] <emeb> ghoti: AHA!
  • [02:40:49] <emeb> you need to update the MLO in NAND
  • [02:40:50] <ghoti> ?
  • [02:41:15] <ghoti> emeb, are there instructions for that on http://elinux.org/BeagleBoardUbuntu as well?
  • [02:41:21] <emeb> nope
  • [02:41:43] <emeb> koen has a script to fix that
  • [02:41:48] <ghoti> Not even in "Troubleshooting"? (which contains 3 lines of instructions for something ubuntu-related)
  • [02:41:49] <emeb> but I don't remember where he put it
  • [02:42:25] <emeb> he's mentioned here a few times though - you could trawl through the logs
  • [02:45:10] <ghoti> So ... I'm still not clear on all this. NAND is a chunk of Flash memory. Could I potentially use that instead of the small FAT filesystem on my SD card? Store uImage there too?
  • [02:45:23] <emeb> ghoti: absolutely
  • [02:45:33] <emeb> it's 256MB
  • [02:45:39] <ghoti> Lots of room.
  • [02:45:54] <ghoti> Can it not be accessed as a disk device from a running OS?
  • [02:45:59] <emeb> you can boot w/o SD that way
  • [02:46:04] <ds2> do it all the time
  • [02:46:07] <emeb> yes - you can set up an FS on it
  • [02:46:12] <ds2> easier then dealing with the silly SD cards
  • [02:46:44] <emeb> access the NAND fs even if you boot from SD
  • [02:47:44] <djlewis> ghoti: the bottom of this page tells you how to update MLO

  • [02:48:28] <djlewis> I used it a few weeks ago as my BB was doing that though user button did not work.
  • [02:48:35] <ghoti> Does "fatload mmc 0 82000000 MLO
  • [02:48:37] <ghoti> wups
  • [02:48:47] <ghoti> does that load the MLO file that's on my SD card's FAT filesystem?

  • [03:07:33] * ghoti rationalizes deserving icecream

  • [03:08:37] <emeb> temp didn't drop below 100F until about 3AM

  • [03:09:18] <djlewis> but did you have 80% humidity?
  • [03:09:21] <emeb> ds2: that would be good.
  • [03:09:38] <ghoti> I'll be in Northern Sweden in 2 weeks. Should have much more reasonable temperatures there.
  • [03:09:46] <emeb> we went up Mt Lemmon outside Tucson last weekend. > 8000' and pleasant on top.
  • [03:10:11] <emeb> saw a wildcat run across the road!
  • [03:10:11] <ds2> Mmmmm 8000 ft... great place for sprinting around

  • [03:12:04] <ghoti> ah.
  • [03:12:08] <ds2> sounds a great place to drive a carburated car that was tuned in deathvalley
  • [03:12:16] <ghoti> heh
  • [03:12:34] <djlewis> emeb was probably changing a fpga in a satellite

  • [03:13:13] <djlewis> nine hot babes and me would be ok
  • [03:13:17] <ds2> emeb: I'd do it... only problem I see is the toll to cross the panama gap
  • [03:14:01] <emeb> and driving through Columbia could be ... interesting

  • [06:44:15] <av500> come on, its shows that ffmpeg owns fftw by 800 :)
  • [06:45:05] <ds2> how does a fft relate to a dct?

  • [06:45:27] <ds2> :D

  • [06:47:06] <hitlin37> this is the huge difference
  • [06:47:28] <av500> yes, ffmpeg leads by 800 gigmolongs
  • [06:47:32] <mru> fft is a method of calculating a dft
  • [06:47:48] <av500> he said dct
  • [06:47:52] <mru> dct uses only cosines
  • [06:47:58] <av500> is there a dst?
  • [06:48:02] <mru> yes
  • [06:48:05] <ds2> av500: I know the first point
  • [06:48:11] <mru> dct is good for even functions
  • [06:48:15] <ds2> but isn't the result of a FFT all real?
  • [06:48:16] <mru> dst for odd functions
  • [06:48:21] <hitlin37> is there similar comparison exits for ffmpeg vs openmax
  • [06:48:24] <av500> dst is good for memcpy as well :)
  • [06:48:28] <mru> the result of an fft of real values is complex
  • [06:48:36] <av500> hitlin37: the comparison is bogus
  • [06:48:48] <hitlin37> why
  • [06:48:50] <mru> hitlin37: ffmpeg is no doubt much faster
  • [06:48:58] <mru> exactly how much is impossible to tell from that graph
  • [06:49:00] <ds2> mru: that part I can't seem to wrap my mind around... how do you represent complex values with integers?
  • [06:49:17] <mru> ds2: you don't
  • [06:49:21] <mru> this is all floating-point
  • [06:49:26] <hitlin37> agree but facts should always b there to prove
  • [06:49:33] <mru> and a complex value is represented with a pair of floats
  • [06:49:43] <mru> pairs of ints could represent complex integers of course
  • [06:50:01] <ds2> so for an array of 64 points input, you get back 128 floats (64real, 64 imag.)?

  • [07:40:06] <av500> ppoudel: btw, cmem buffers can be allocated as "cached" in which case they are fast er to use from the gpp and must be flushed before passing to the DSP
  • [07:40:22] <av500> faster if you do read modify write on them
  • [07:40:29] <av500> simple memcpy into them not
  • [07:40:41] <ppoudel> av500: ok
  • [07:41:12] <av500> i have no idea what kind of buffer managment opencv does
  • [07:41:27] <mru> probably convoluted
  • [07:41:32] <av500> and whether it has an idea about where a buffer is from
  • [07:42:18] <ppoudel> av500: How can it be used as cached buffer? Is there any special instruction to follow?
  • [07:42:51] <av500> Memory_AllocParams
  • [07:43:03] <av500> Memory_CACHED
  • [07:43:25] <av500> should be in cmem/ce docs
  • [07:43:27] <ppoudel> av500: Thanks
  • [07:43:33] <mru> or in the source
  • [07:43:43] <av500> http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/ce/2_25_01_06/exports/codec_engine_2_25_01_06/docs/html/group__ti__sdo__ce__osal___memory.html
  • [07:44:11] <av500> and then Memory_cacheInv() before passing to dsp
  • [07:44:23] <av500> err, Memory_cacheWb() :)
  • [07:44:39] <av500> or Memory_cacheWbInv()
  • [07:45:08] <ppoudel> av500: thanks
  • [07:46:24] <av500> ppoudel: so, you need to teach videoFrame = cvQueryFrame ( capture ); to allocate from CMEM
  • [07:46:41] <av500> good luck :)
  • [07:46:43] <ppoudel> av500: Do I have to do any cache management on the DSP algorithm?
  • [07:46:48] <av500> n
  • [07:46:50] <av500> o
  • [07:46:54] <av500> no
  • [07:46:56] <ds2> what about cash management?
  • [07:47:04] <av500> send all to me
  • [07:47:11] <av500> I'll just manage
  • [07:47:14] <ppoudel> Ok, probably that is what I was missing.
  • [07:47:25] <ppoudel> ;)
  • [07:47:37] <av500> ppoudel: if you use the DSPs caches, yes you have to manage it
  • [07:47:55] <av500> so on the dsp side you have to write back before you return from process()
  • [07:48:10] <ppoudel> I was actually copying the video frame to CMEM allocated memory.
  • [07:48:11] <av500> but that is unrelated to whether cmem is cached on gpp
  • [07:48:25] <mru> you could use the dsp sram as normal memory and read/write it directly from arm side
  • [07:48:28] <av500> ppoudel: yes, I saw that and did not like it
  • [07:48:37] <av500> mru: yes, but not using CE
  • [07:48:38] <mru> you could probably even convince cmem to manage it for you
  • [07:48:54] <ppoudel> I will figure it out.
  • [07:49:14] <mru> av500: is CE a pile of stupid ideas and nothing else?
  • [07:49:16] <av500> and opencv will handle potentially large images, so dps sram might be to small
  • [07:49:26] <mru> process them in slices
  • [07:49:32] <av500> mru: I dont bite
  • [07:49:47] <ddd_> thanks, ppoudel and av500, i check out like "svn checkout http://opencv-dsp-acceleration.googlecode.com/svn/trunk/ opencv-dsp-acceleration-read-only "

  • [08:27:48] <amol112_> hi all, i want to connect BB to my monitor using hdmito vga cable can you please tell me while purchasing what type of cable i should see
  • [08:28:12] <av500> none
  • [08:28:19] <av500> upgrade your monitor to hdmi
  • [08:28:36] <av500> or buys a very expensive active HDMI to VGA converter
  • [08:28:44] <amol112_> hmm i want to connect using vga port only
  • [08:28:48] <av500> or buy that beagleboardtoys vga thingy
  • [08:28:52] <theholyduck> amol112_, well vga is essentially analog
  • [08:28:57] <theholyduck> and hdmi/dvi are digital
  • [08:29:07] <theholyduck> the signals arent compitable
  • [08:29:09] <dm8tbr> that active converter is prolly is more expensive than an new monitor?
  • [08:29:16] <theholyduck> dm8tbr, probably
  • [08:29:18] <theholyduck> and bad quality
  • [08:29:22] <theholyduck> etc
  • [08:29:29] <amol112_> theholyduck: i have hdmito dvi cable so do i need converter?

  • [08:29:48] <theholyduck> amol112_, hdmi to dvi works fine because they are identical
  • [08:29:53] <theholyduck> as in, the signal transmitted is identical
  • [08:30:00] <theholyduck> heck, the hdmi port on the bb is just a dvi port

  • [15:56:41] <mru> lool: the topic is ffmpeg
  • [15:56:52] <lool> Oh
  • [15:57:05] <_koen_> and running ubuntu on non TI v7 chips
  • [15:57:08] <lool> So ffmpeg has some logic in the source package to only build the required number of passes
  • [15:57:10] <_koen_> the ones without the nightlight
  • [15:57:23] <lool> ffmpeg has some vfp, armv6, and some NEON bits
  • [15:57:34] <mru> I know ffmpeg pretty well
  • [15:57:44] <_koen_> mru: really?
  • [15:57:46] <lool> When the debianized source package builds, it detects the toolchain defaults, and decides which passes it should do
  • [15:57:57] <av500> mru: dont be so hard, only the few NEON bits have to go ... :)
  • [15:58:08] <lool> This is in debian/confflags
  • [15:58:11] <_koen_> it's not like those make a difference
  • [15:58:12] <mru> when proper ffmpeg builds, it detects what the toolchain is targeting and optimises for that
  • [15:58:21] <lool> mru: Yes
  • [15:58:24] <lool> mru: But we do extra psses
  • [15:58:34] <lool> so that on Debian, you get a vfp version of ffmpeg in usr/lib/vfp
  • [15:58:40] <lool> and on Ubuntu, you get a neon one
  • [15:58:42] * Ralph_ (86e25636@gateway/web/freenode/ip.134.226.86.54) has joined #beagle
  • [15:58:52] <lool> debian/confflags tests the toolchain defaults to decide which passes to enable
  • [15:59:03] <lool> if the toolchain defaults to vfp, it doesn't do a VFP pass since the main pass will have it
  • [15:59:15] <mru> so far, so good
  • [15:59:24] <lool> So that's all I had :-)
  • [15:59:29] <lool> On Debian we do vfp + neon
  • [15:59:30] <_koen_> so ubuntu won't run on tegra2 and armada?
  • [15:59:32] <mru> why are they telling I have to conjure up runtime detection to keep neon?
  • [15:59:32] <lool> and on Ubuntu we do neon
  • [15:59:35] <lool> (on top of main pass)
  • [15:59:42] <lool> the main pass uses the toolchain defaults
  • [15:59:58] <lool> _koen_: it does, the main pass doesn't have neon
  • [16:00:21] <lool> _koen_: But the neon optimized pass is put in usr/lib/vfp/neon and only picked up by the runtime linker if you have neon
  • [16:00:21] <av500> mru: might be solved with a fatelf ffmpeg binary :)
  • [16:00:31] <_koen_> ah, you're using hwcaps
  • [16:00:48] <lool> Ok; I have to drop off for a call, leave me questions here if you have more, but you seem to have gotten the idea anyway ;-)
  • [16:00:49] <_koen_> saying 'hwcaps' would have been a lot shorter
  • [16:00:56] <mru> lib/vfp/neon... so no integer-only neon support?
  • [16:00:58] <lool> Yes, it's using eglibc hwcaps
  • [16:01:01] <mru> </troll>
  • [16:01:09] <lool> but the term hwcaps has been used for multiple things, so careful ;)
  • [16:01:16] <_koen_> not on arm
  • [16:01:37] <_koen_> I used to disable hwcaps siince it saved a dozen stat() calls for every lib
  • [16:01:47] <_koen_> and jffs2 isn't a speed daemon in that regard
  • [16:01:55] <lool> stat is cheap
  • [16:01:59] <lool> ah jffs2
  • [16:02:00] <lool> sorry about that

  • [19:14:23] <Redb3ard> My understanding is that undervoltage can't generally cause destruction.
  • [19:14:37] <Redb3ard> It just won't power on, or if it does behavior will be unpredictable.

  • [19:15:35] <Redb3ard> Yes, there are...

  • [19:44:55] <mru> I only build ffmpeg with it
  • [19:45:38] <ds> luck, clearly
  • [19:46:01] <mru> it supports almost all gcc extensions
  • [19:46:09] <mru> but command line is slightly different
  • [19:46:29] <mru> you can probably create a wrapper script easily enough
  • [19:46:32] <ds> i've written wrappers for several other compilers to satisfy autoconf
  • [19:47:02] <mru> with a couple of initial flags it accepts most gcc flags
  • [19:47:33] <ds> is it capable of producing shared libraries?
  • [19:47:37] <mru> yes
  • [19:47:45] <mru> the linker knows all the gnu tricks
  • [19:47:53] <ds> ok, so the main problem is getting through configure
  • [19:48:13] <mru> a wrapper should be almost trivial actually
  • [19:48:28] <mru> there are instructions in the documentation
  • [19:48:34] <mru> for gcc compat mode
  • [19:48:54] <ds> it's mostly just blatant autoconf bugs that one needs to work around

  • [22:30:19] <robtow> sakoman_ got a question, if you have a moment or two.
  • [22:30:47] <sakoman_> robtow: sure
  • [22:31:33] <robtow> sakoman_ wondering if there is an easy way to turn off stuff in the OMAP3530 using devmem2 - like the dsp, video, etc.
  • [22:31:47] <_av500_> there are apis for that
  • [22:32:07] <robtow> _av500_ pointer(s) to those?
  • [22:32:12] <sakoman_> indeed! devmem2 is probably the wrong method
  • [22:32:27] <_av500_> robtow: dsp should be off unless you use it
  • [22:32:28] <robtow> sakoman_ I *knew* it was a naive question :-)
  • [22:32:34] <_av500_> video use sysfs for omapfb
  • [22:32:36] <sakoman_> robtow: do you ever need any that stuff?
  • [22:32:37] <_av500_> and omapdss
  • [22:32:55] <sakoman_> if not, you could simply disable it in your kernel build
  • [22:33:33] <robtow> sakoman - want to turn stuff like ethernet and usb on and off; disable video, audio codec, dsp.
  • [22:33:54] <_av500_> use all the corresponding high level apis

  • [22:41:52] <djlewis> sakoman_: can I bring my three dogs and my BB and telescope and live in your tool shed :) ?
  • [22:42:03] <robtow> sakoman_ - it's difficult to figure it all out from the TI data sheets, and what is around in wikis
  • [22:42:25] <sakoman_> djlewis: I don't think you would like that -- it is 112F today
  • [22:42:34] <djlewis> hmmm
  • [22:42:35] <sakoman_> probably a lot hotter in the tool shed!
  • [22:43:26] <sakoman_> but go ahead and send the telescope ;-)
  • [22:43:31] <djlewis> been overcast hrer so it only reached 94 with a 106 something index.

  • [22:43:59] <sakoman_> yeah, seems that way
  • [22:44:12] <emeb> what's the humidity?
  • [22:44:29] <sakoman_> probably something like 3% :-)

  • [22:45:09] <sakoman_> djlewis: yup, no city lights you can see the milky way

  • [22:46:08] <emeb> djlewis: you can't sweat in that kind of weather - water condenses on you.
  • [22:46:08] <sakoman_> emeb: they say we may get some of your monsoon moisture since the winds are from the south
  • [22:46:18] <sakoman_> I hope they are wrong
  • [22:46:22] <djlewis> 30% ! we never get that low
  • [22:46:38] <emeb> sakoman_: everyone needs rain.
  • [22:46:41] <sakoman_> djlewis: yeah, the combination of low humidity and no lights makes for nice start viewing
  • [22:47:33] <djlewis> with our avg humidity, dew would irragate..
  • [22:47:38] <djlewis> irrigate

  • [22:48:15] * djlewis hit the ice cream early since I stayed home today.
  • [22:48:48] <emeb> sakoman_: here's an on-topic question - do you know of a kernel driver for the McBSP (aside from the one used in the audio system)?
  • [22:49:03] <emeb> ds2: says he thought there was one in an old TI kernel...
  • [22:49:10] <sakoman_> emeb: nope that is the only one
  • [22:49:42] <sakoman_> djlewis: mmm . . . ice cream sounds reall good
  • [22:49:43] <emeb> dang. Was hoping for something along the lines of spidev
  • [22:49:58] <sakoman_> emeb: sorry not aware of anything like that
  • [22:50:10] <emeb> sakoman_: ok - thx
