  • [02:53:18] <beagleuser> HI ALl
  • [02:53:22] <beagleuser> Hi All
  • [02:53:43] <beagleuser> I am trying to build the Angstrom kernel
  • [02:54:17] <beagleuser> I am trying to build the Angstrom kernel : # bitbake nano
  • [02:55:06] <beagleuser> and i am getting the following error: Unable to open conf/bitbake.conf
  • [02:58:48] <bmxr> beagleuser: you do understand that command only build nano right?
  • [03:03:06] <beagleuser> I want to build the kernel source
  • [03:03:40] <beagleuser> i executed all the commands given in the openembedded site http://wiki.openembedded.net/index.php/Getting_started
  • [03:04:18] <beagleuser> Now how to get the kernel source.. actually i want to get the kernel source for Beagle board
  • [03:05:04] <beagleuser> Have you any time downloaded the Kernel source using the OE
  • [03:05:39] <russ> its not a spoon feeding guide
  • [03:06:43] <beagleuser> Can you please help me in downloading the kernel for Beagle? I have setup Bitbake and OE every thing
  • [03:06:49] <russ> why not just use a pre-built kernel?
  • [03:07:14] <beagleuser> i can not use the demo thing because i need to modify few things in the kernel source tree and build it again and use it..
  • [03:07:28] <russ> like...?
  • [03:07:49] <beagleuser> i want to enable the NEON processor.. this can be done in the menu config
  • [03:08:15] <beagleuser> and build the CMEM and DSP w.r.t this kernel...
  • [03:08:16] * brolin (n=brolin@190.157.13.75) has joined #beagle
  • [03:08:25] <russ> no, the neon isn't enabled in the kernel config afaik
  • [03:08:41] * djlewis (i=4b0f4002@gateway/web/ajax/mibbit.com/x-9801b7a77c14dc0e) has joined #beagle
  • [03:08:43] <beagleuser> ya.. thats why i want to enable it and then build and use it..
  • [03:08:47] <russ> the only kernel config option related to neon is to utilize neon for vfp, which wouldn't really matter anyway
  • [03:09:02] <russ> I mean there isn't a "NEON" option
  • [03:09:37] <beagleuser> ya.. i want to enable the vfp and us it..
  • [03:09:49] <russ> why would you want to use the in kernel floating point emulator?
  • [03:10:27] <beagleuser> i have few things to be run on that so... it is a requirement from my side to enable that and give..
  • [03:11:26] <russ> I think you are really confused
  • [03:11:57] <beagleuser> ok.. let me get few things cleared... is the NEON processor enabled by default in the kernel?
  • [03:12:03] <russ> and anyway, the angstrom image has NEON support enabled for in kernel floating point emulation, which probably either isn't what you think it is, has nothing to do with what you are doing, or both
  • [03:12:04] <russ> yes
  • [03:12:43] <beagleuser> oh ok.... then let me try using the pre-built kernel..
  • [03:12:54] <russ> and the newest demo images have dsp support iirc
  • [03:13:20] <beagleuser> oh ok... thank you for clarifying the doubt....Few more things
  • [03:13:31] <beagleuser> where can i get the latest pre-built demo things

  • [03:15:53] <beagleuser> Can i also get the prebuilt CMEM and DSP for this.. so that i can use the DSP also
  • [03:16:22] <russ> like I said, I think the latest images have dsp support, but I'm not sure how that gets exposed
  • [03:17:28] <beagleuser> Now to build the CMEM and DSP .... i ned the kernel source :-)
  • [03:17:43] <russ> why not try the angstrom demo image first?
  • [03:17:52] <bmxr> beagleuser: did you dry the demo image first?
  • [03:18:01] <bmxr> lol @ russ
  • [03:18:06] <bmxr> same question
  • [03:19:11] <russ> and plus, if you are having difficulties with the openembedded getting started page, building your own kernel under openembedded will be a difficult task
  • [03:19:59] <beagleuser> ya i can use the pre-built kernle.. but if i dont have CMEM and DSP.ko's i will not be able to use the DSP
  • [03:20:34] <bmxr> beagleuser: Did you try the pre-built kernel to see if it offers what you require?
  • [03:21:13] <beagleuser> yes i downloaded the image and modules.... the modules has .kos of the kernel and not the CMEM and DSP.kos
  • [03:21:38] <bmxr> ok
  • [03:22:03] <beagleuser> So please can you guys help me in downloading the kernel source....
  • [03:23:11] <russ> thats the easiest step though...
  • [03:24:18] <russ> also, just because there isn't a module doesn't mean it isn't built into the kernel
  • [03:24:39] * brolin (n=brolin@190.157.13.75) Quit (Client Quit)
  • [03:25:07] <beagleuser> the CMEM and DSPlink. components are not part of the kernel.. they are part of TI's DVSDK
  • [03:25:33] <beagleuser> and these two components are built with seperate procedure..
  • [03:25:47] <beagleuser> so i dont think these can be part of the kernel
  • [03:25:50] <russ> then you don't need to reconfigure a kernel, do you
  • [03:26:14] <russ> you need to build the modules against the kernel headers
  • [03:26:53] <beagleuser> exactly.. so atleasti need the kernel headers to build the CMEM And DSP
  • [03:27:13] <russ> maybe there is an ipk?
  • [03:28:05] <beagleuser> What is ipk?
  • [03:28:08] <russ> hmmm
  • [03:28:25] <russ> you don't seem to be searching very hard and/or haven't tried out the demo image
  • [03:29:20] <russ> you haven't tried out the latest angstrom demo image, have you?
  • [03:30:00] <beagleuser> i have tried 27.. not 28..
  • [03:30:44] <russ> yes, you want the latest one
  • [03:30:57] <russ> Angstrom-Beagleboard-demo-image-glibc-ipk-2009.X-test-20090326-beagleboard.rootfs.tar.bz2

  • [03:31:08] <russ> uImage-2.6.28-r17-beagleboard.bin
  • [03:31:47] <russ> it should include the ti-cmem-module and dsplink-module angstrom packages
  • [03:32:21] <beagleuser> i downloaded modules... but i dint see cmem.ko inside it.. Any idea where it should be
  • [03:32:51] <russ> modules-2.6.28-r17-beagleboard.tgz are modules that got built with the kernel

  • [03:33:42] <beagleuser> yes true... so what about cmem and dsp modules
  • [03:34:06] <russ> why not try the angstrom demo image
  • [03:35:42] <beagleuser> ok i will try it and come back.... than you for your time... But mean while if you have any docs which describes about downloading the kernel source tree please do send.. it may be required for me later. if i need to add few things into it... if you come across any docs later please mail me at santosh.pattar@gmail.com

  • [03:36:10] <russ> there isn't a document, its understanding several systems
  • [03:36:52] <russ> each document assumes that you have some understanding of connected systems and technologies
  • [03:38:45] <beagleuser> oh ok.. But have you any time downloaded the kernel source?
  • [03:39:33] <russ> all the time
  • [03:39:44] <russ> many sources, many trees
  • [03:39:57] <beagleuser> then tell me also even i also want to start downloading the source trere
  • [03:42:06] <russ> http://kernel.org
  • [03:43:42] <beagleuser> one more thing i want to ask.... i want to recreate the Beagle kerbel 2.6.28.. so which kernle do i need to download from kernel.org and what all patches do i need to apply tp get the 2.6.28 kernel
  • [03:43:58] <russ> you'd probably want to fetch one of the omap git trees
  • [03:45:07] <beagleuser> yes any thing should be ok... but i want to recreate the Beagle Angstrom kernel 2.6.28
  • [03:45:41] <russ> then everything you know is in the openembedded receipie
  • [03:46:22] <russ> er, everything you need to know
  • [03:46:31] <russ> the location of the source, the defconfig, any extra patches, etc
  • [03:48:50] <beagleuser> thank you..
  • [03:48:57] <russ> also, the elinux wiki is a great source of info
  • [03:48:59] <russ> http://elinux.org/BeagleBoard#Linux_kernel
  • [03:50:07] <russ> and yes, the angstrom demo image has a cmemk.ko, a dsplinkk.ko and a lpm_omap3530.ko
  • [03:51:40] <beagleuser> are they part of the image itself?
  • [03:52:15] <beagleuser> or can i download the .kos?

  • [07:12:17] <beagleuser> i am trying to build Angstrom image using OE.. (instructions from http://www.angstrom-distribution.org/building-%C3%A5ngstr%C3%B6m)
  • [07:12:41] <beagleuser> i want to build uImage
  • [07:12:57] <beagleuser> what should be the build command
  • [07:13:41] <beagleuser> in the link now it is: bitbake base-image ; bitbake console-image ; bitbake x11-image
  • [07:13:49] <beagleuser> what should it be for uImage
  • [07:14:00] <beagleuser> will it down load the source tree also?

  • [08:22:17] * ArteK (n=Artur@81.15.241.96) has joined #beagle
  • [08:22:23] <geckosenator> I'm working on my superoptimizer
  • [08:22:46] <ds2> eh?what's that?
  • [08:22:47] <geckosenator> ds2: are you ready to make the second version of the board now?
  • [08:23:04] <ds2> geckosenator: yep... even looked at some mfg prospects at ESC
  • [08:23:06] <geckosenator> ds2: it takes assembly code and rearranges it to reduce code size
  • [08:23:20] <geckosenator> like, replaces some instructions with others
  • [08:23:40] <ds2> ah
  • [08:23:56] <geckosenator> but it can eliminate loops
  • [08:23:59] <geckosenator> if they are simple enough
  • [08:24:15] <geckosenator> depending on how much ram you have :-P
  • [08:24:25] <ds2> how much code can it see at once?
  • [08:24:34] <geckosenator> it depends on the instructions
  • [08:24:46] <geckosenator> like bit shifting and bitwise ops are easy
  • [08:24:51] <geckosenator> since it tracks changes at the bit level
  • [08:24:55] <geckosenator> so it can do a lot of them
  • [08:25:07] <geckosenator> but if you do even addition or subtraction, it has trouble
  • [08:25:16] <geckosenator> can't do more than a few of those
  • [08:25:38] <geckosenator> unless you happen to do other stuff which allows it to eliminate unknowns
  • [08:26:05] <geckosenator> anyway.. I think you should have a 3.7v regulator on the next board
  • [08:26:10] <geckosenator> to power the beagle at lower voltage
  • [08:26:35] <ds2> the issue there is it kills the EHCI port
  • [08:26:53] <geckosenator> I don't understand why you can't use a powered hub
  • [08:27:02] <geckosenator> you are afraid the hub will backfeed?
  • [08:27:19] <geckosenator> I could just cut the power wire in the usb cable going from the EHCI port to the hub
  • [08:28:11] <ds2> a powered hub is cumbersome ANDmay be confused
  • [08:28:37] <ds2> as even a self powered up uses the V-bus to drive pull ups to id it as a HS/FS device
  • [08:28:39] <geckosenator> well we already have a powered hub elsewhere
  • [08:28:48] <ds2> and making the pull ups run at <5V will confuse things
  • [08:28:53] <geckosenator> well the beagle has a linear regulator?
  • [08:29:00] <geckosenator> is that why it's more efficient to run at lower voltage?
  • [08:29:30] <geckosenator> the pullups on the usb dataline?
  • [08:30:00] <geckosenator> that's handled by the hub
  • [08:30:38] <ds2> the Vbus on the EHCI has no regulator
  • [08:30:54] <ds2> no the pull ups as seen by the beagle phy
  • [08:31:18] <ds2> the reason it should run the pull ups off Vbus instead of its internal power supply is to elminate backfeed

  • [08:36:32] * ogra (n=ogra@ubuntu/member/ogra) has joined #beagle
  • [08:38:04] <geckosenator> well I would cut backfeed
  • [08:38:08] <geckosenator> so it wouldn't be possible
  • [08:38:31] <ds2> not an option unless you also are designing a hub
  • [08:38:35] <geckosenator> otherwise is the ehci as buggy as the otg port?
  • [08:38:46] <ds2> nope. EHCI is reliable otherwise
  • [08:38:54] <geckosenator> hmm
  • [08:39:21] <geckosenator> well I don't understand why the beagle doesn't use switching regulators
  • [08:39:29] <geckosenator> so that it doesn't matter if you power the board at 5v
  • [08:39:37] <geckosenator> otherwise, is there a trace you can cut?
  • [08:39:56] <ds2> no, the trace is buried (I asked for the ability to cut a trace and Gerald said it is too late)
  • [08:40:16] <ds2> the way to work around that is desolder the A connector, bend up the Vbus pin and feed it 5V that way
  • [08:40:59] <geckosenator> oh, that's easy
  • [08:41:08] <geckosenator> I would just unsolder that 1 pin
  • [08:41:21] <geckosenator> then solder a wire to it to 5v
  • [08:41:37] <ds2> well, it is a connector, you need to desolder the whole thing bend up the pin, and resolder it back
  • [08:41:42] <ds2> it is throughhole
  • [08:41:56] <geckosenator> the pin is under it?
  • [08:42:09] <geckosenator> well it seems like if the hub is powered
  • [08:42:33] <geckosenator> then all you need to do is splice the wire in the cable
  • [08:42:38] <geckosenator> and feed it around back to it's own 5v
  • [08:42:55] <geckosenator> then just power the hub at 5v and do nothing to the beagle
  • [08:42:57] <ds2> yes, it is under
  • [08:43:05] <ds2> you can splice the cabletoo
  • [08:43:11] <ds2> but that is ugly
  • [08:43:55] <geckosenator> yes but it would save a lot of power
  • [08:44:05] <geckosenator> well..hmm
  • [08:44:08] <ds2> If I were to do it, I'd do it at the connector
  • [08:44:15] <geckosenator> the expansion board could do it
  • [08:44:17] <ds2> I hate random cables running all over
  • [08:44:28] <geckosenator> hmm
  • [08:44:36] <geckosenator> well if the expansion board had a hub chip
  • [08:44:45] <geckosenator> then it would be easy
  • [08:44:49] <ds2> I'll post the pictures of the insides to show what I have
  • [08:44:54] <geckosenator> ok
  • [08:44:54] <ds2> why?
  • [08:45:04] <ds2> there is no USB signals available on that connector
  • [08:45:11] <ds2> you still need to hihack the USB port
  • [08:45:18] <geckosenator> you would have to have a usb cable
  • [08:45:22] <geckosenator> going from beagle to expansion
  • [08:45:28] <geckosenator> but you wouldn't need to splice anything
  • [08:45:36] <geckosenator> to run the beagle at a lower voltage
  • [08:45:46] <ds2> essentially that's a custom hub
  • [08:45:56] <geckosenator> yeah, true :/
  • [08:46:00] <ds2> in that case, I'd just put it on a different board... neater that way
  • [08:46:04] <geckosenator> well let me see the pictures
  • [08:46:20] <ds2> I am just poof'ed out... but I am done with my talks
  • [08:46:47] <ds2> geckosenator: recruit people to help defray development costs
  • [08:47:17] <geckosenator> yeah
  • [08:47:22] <geckosenator> I will try
  • [08:47:58] <ds2> I wonder if it is inappropriate of me to throw together a mailing list of people interested to see if we can find a common ground
  • [08:48:17] <ds2> the more boards we make, the cheaper it is... just because boards are NRE + per board costs
  • [08:48:24] <geckosenator> yeah
  • [08:48:30] <ds2> get enough volume, we can do entire panels and avoid the aggregators
  • [08:48:31] <geckosenator> well I can assemble my own board
  • [08:48:42] <ds2> you can but I donno if others can
  • [08:48:46] <geckosenator> yeah, if you could do like 1000 or so..
  • [08:48:51] <ds2> some people are scared of the 0.100 connectors
  • [08:49:01] <geckosenator> well they should just try
  • [08:49:09] <geckosenator> since it's actually pretty easy
  • [08:49:26] <geckosenator> anyway.. I would like a way to hook up larger lcds
  • [08:51:17] <ds2> I actually have a pile of LCDs at the moment... issue is more the half of them lack inverters to drive the backlight
  • [08:52:12] <geckosenator> well the expansion board does it
  • [08:52:53] <geckosenator> I don't thing I want compact flourecent anyway
  • [08:53:15] <ds2> LED backlighting on the bigger LCDs aren't that common

  • [09:35:09] <recalcati> I dsiconnected it : no more messages, now I reconnect it, kernel messages again
  • [09:38:29] <AV500> tomba: about dss2, there is a potential race when using v4l
  • [09:39:42] <tomba> what do you mena? dss2 doesn't support v4l
  • [09:39:45] <tomba> mean
  • [09:40:08] <AV500> yes, but I have a TI kernel here where v4l uses DSS2 to display frames
  • [09:40:12] <AV500> this not supported?
  • [09:40:53] <tomba> well it's very much work in progress. I wouldn't call it supported. but anyway, what kind of race?
  • [09:41:07] <AV500> well, you do:
  • [09:41:18] <AV500> v4l->open: --> ovl->enable
  • [09:41:29] <AV500> v4l qbuf-> queue buffer
  • [09:41:37] <AV500> user space: sysfs/ovl enable

  • [09:43:40] <AV500> git.omapzoom
  • [09:44:22] <tomba> yeah, there are tons of similar race conditions. I haven't done much work on locking, as omapfb has been the only user for dss2. but, yes, at some point I should try to go through the APIs and implement proper locking
  • [09:45:05] <AV500> problem is that mgr->apply needs to be called from IRQ, so I don't know if you can make it wait for a lock
  • [09:45:49] <tomba> what IRQ is that? VSYNC?
  • [09:47:09] <AV500> basically yes
  • [09:48:05] <AV500> we spent quite some time on making that part work in the past, so I know it is not trivial :-)
  • [09:48:16] <tomba> the configuration of overlays etc is unbelievably complex operation, if done properly, and I haven't still figured out how to do it correctly
  • [09:48:57] <AV500> yes, and you try to make it "universally" useable, whereas we could ignore all the stuff that we didn't neet
  • [09:49:44] <tomba> sometimes I feel that the whole dss2 driver is doomed to never work correctly =)
  • [09:50:26] <AV500> but still the "structure" is much better than what was there in the past
  • [09:50:33] <AV500> so kudas for that
  • [09:50:36] <AV500> so kudos for that
  • [09:50:58] <tomba> thanks =)
  • [09:54:20] <AV500> actually, the only "scary" thing is this go bit handling
  • [09:55:56] <AV500> also, mgr->apply called from an IRQ should not call a dispc_go that waits for something in a while loop,
  • [09:56:15] <AV500> I think it works by chance atm as the VSYNC IRQ has just cleared the go bit.
  • [09:56:31] <tomba> well, there are many other scary parts, but perhaps they are more hidden =).
  • [09:57:16] <AV500> tomba: well, as I said, we did not venture into every dark alley
  • [09:57:42] <tomba> I'm not quite sure what would be the proper way to handle this all. I think best option would be to have all overlay parameters in OMAP's ram. they would then be pushed to DSS registers when needed, and DSS would then apply those at VSYNC.
  • [09:58:04] <tomba> but to make things more complex, some DSS registers are these shadow registers updated at VSYNC, and some are not
  • [09:59:41] <AV500> actually, what we found is that most of the time the "wait" part of the go bit setting is not needed

  • [10:04:30] <tomba> AV500: well, somebody definitely needs to sync with the go bit. otherwise we can get only part of the new configuration pushed to DSS.
  • [10:04:51] <tomba> I'm not saying the syncing works at the moment though =)
  • [10:05:09] <tomba> but I think caching the configuration values in RAM would make it a bit simpler
  • [10:05:34] <AV500> tomba: yes, mainly when really enabling/disabling the displays, then you wait. but in order to push an updated buffer addr, no wait needed
  • [10:05:57] <mru> most settings don't need the go command
  • [10:05:59] <AV500> we already added a 2nd dispc_go call for that

  • [10:11:37] <mru> latching on vsync makes sense

  • [12:35:14] <Crofton> as he has in the past
  • [12:35:24] <likewise> koen: because the -rt teams latest stable for ARM is 2.6.24, but effort is to make 2.6.29-rt stable for ARM *as we speak*, so the timing would be perfect.
  • [12:35:24] <koen> Crofton|work: he's waiting for crucial fixes

  • [15:24:13] <eFfeM> xander load it from the c2 validation page
  • [15:24:34] <Xander85> sorry, where do I find that
  • [15:24:51] <eFfeM> http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidation
  • [15:25:11] <Stskeeps> eFfeM: did your MMC timing fix make it into anywhere btw?
  • [15:25:21] <Xander85> ok cool thanks!
  • [15:25:36] <eFfeM> Stskeeps: it is in the .28 kernel that is on the feed, it is not in .27 or .29
  • [15:25:50] <Xander85> another quick issue: does anyone know if it possible encode video at 1024 x 768, ffmpeg is locking up larger than 800x600.
  • [15:26:05] <Xander85> being new I don't know much about DSP and how/if to use it for video encoding
  • [15:26:08] <Stskeeps> eFfeM: alright, thanks - i got tired of the beagle seemingily eating my cards ;)
  • [15:27:34] <eFfeM> Xander85: technically it should be possible, no idea why ffmpeg locks up, but i also doubt it is using the dsp
  • [15:27:49] <mru> ffmpeg does not use the dsp
  • [15:27:57] <eFfeM> Stskeeps: i only had the problem with sdhc cards, but there is an if in the code for sdhc
  • [15:28:04] <mru> ffmpeg *will* make the omap lock up if you have an old u-boot
  • [15:28:17] * koen hugs l1neon
  • [15:28:30] <eFfeM> Stskeeps: regular sd worked for me, but apparently sdhc also works for others (like koen :-) )
  • [15:28:50] <eFfeM> my 2 cards are both kingston 4gb sdhc class 6
  • [15:29:01] <Stskeeps> yeah, similar
  • [15:29:14] <Xander85> what is the latest release? i dont see any version #s on the revision page im looking at
  • [15:30:07] <eFfeM> koen, do you want me to add the mmc timing patch to 2.6.29 ?
  • [15:30:26] <koen> eFfeM: sure go ahead
  • [15:30:36] <eFfeM> ok, will do later today
  • [15:30:36] <koen> eFfeM: I haven't ran .29 on beagle yet, only on omapzoom
  • [15:30:50] <eFfeM> yeah, saw .29 does not have the ehci patch yet
  • [15:31:06] <koen> any volunteers to rediff the ehci patch?
  • [15:31:31] <eFfeM> might give it a try later tonight, does not look too complicated
  • [15:31:42] <eFfeM> and i want to know if .29 resolves some of my usb issues
  • [15:31:55] <djlewis> so should we newbies with C2 and sdhc use an earlier kernel?
  • [15:32:18] <mru> .29-rc6 works fine for me
  • [15:32:26] <eFfeM> the sdhc issue only occurs with some cards and is fixed in .28
  • [15:32:32] <eFfeM> mru with sdhc? which brand?
  • [15:32:42] <mru> yes, sdhc
  • [15:32:46] <mru> sandisk and kingston
  • [15:33:17] <djlewis> I picked up a couple of Transcend from newegg.
  • [15:33:20] <eFfeM> cool, a good reason to look at the ehci patch :-) will first try the regular build though
  • [15:34:29] <koen> no troubles with sandisk sd and sdhc cards here
  • [15:35:11] <eFfeM> ok, good to know (but I think the local paradigit store only has a-data)
  • [15:35:48] <djlewis> I looked at Kingston and Sandisk but there was a special on a SDHC reader in Transcend
  • [15:36:36] <Jay7> koen: hey :) I'll be happy when you sometimes join kexecboot channel :) even if one per week at evening :)
  • [15:36:50] <Jay7> sometimes we need good advice/decision :)
  • [15:37:06] <koen> :)
  • [15:37:12] <Jay7> /discussion :)
  • [15:37:23] <eFfeM> afk, dinner :-)
  • [15:38:32] * koen notices he lacks eggs to make a breadpudding
  • [15:38:40] <djlewis> I'll test the transcend sdhc 4GB class 6 card soon as I get time, this evening I hope
  • [15:39:43] <koen> the transcend card I have here seems to work as well
  • [15:40:09] <koen> the one from https://specialcomp.com/beagleboard/order.htm
  • [15:40:51] <koen> but I haven't tested that heavily, only first boot and setup mostly

  • [16:54:20] <tharvey> koen, looks like you've been doing a lot of work with 2.6.29 in stable/2009 but 2.6.29-omap is not yet default?
  • [16:54:36] <koen> tharvey: it's default for omapzoom :)
  • [16:54:55] <koen> I haven't booted .29 on beagle yet, since it's missing the ehci patch
  • [16:55:33] <tharvey> ah... cool, then everything else should be good for beagle/overo?
  • [16:55:45] <r3> no such website ? " this is what i purchased, this is how i hooked it up "

  • [16:56:38] <tharvey> ok, thx - I'll kick off a build and give it a spin later today
  • [16:57:28] <tharvey> its nice to see a short list of patches - you all are doing great at getting things into mainline!
  • [16:58:20] <koen> heh
  • [16:58:31] <koen> I just folded the >100 DSS2 patches into one big patch :)
  • [16:59:07] <tharvey> what does DSS2 stand for anyway? Display SubSystem?

  • [17:00:52] <tharvey> its my understanding that to use the DSP you need the dsplink and the ti-gstreamer support/plugin?
  • [17:02:38] <koen> tharvey: right

  • [23:44:18] <Downix> grr, trying to figure out a way to hook up a PCIe 1x bus to the beagle with no luck
  • [23:44:33] <mru> sounds tricky
  • [23:45:02] <Downix> hence my dillema
  • [23:45:11] <mru> how would you even begin?
  • [23:45:16] <Downix> no idea
  • [23:45:30] <mru> the omap doesn't have any form of pci controller
  • [23:45:43] <Downix> my problem is, I have an idea for work, and the OMAP chip fits the needs perfectly save one, no manner of adding minicard support
  • [23:46:10] <russ> you might be able to do it and have it be *really* slow
  • [23:46:19] <russ> but if you need fast, you are probably screwed
  • [23:47:33] <Downix> the ARMs I find with PCIe lack a decent integrated GPU
  • [23:48:19] <russ> what pcie device do you need?
  • [23:48:23] * robclark (n=robclark@nat/ti/x-2de296efc3bda322) Quit (Remote closed the connection)
  • [23:48:58] <Downix> a minicard slot for a custom networking solution my company already has in existing products
  • [23:49:20] <russ> if its custom, why not implement it on the arm?
  • [23:49:39] <Downix> we didn't make the parts on it, just the card itself, and it's supplied to us by 3rd party
  • [23:49:42] <russ> the omap3 has quite a variety of high speed serial interfaces
  • [23:50:11] <russ> does it work like a normal network devices with queues, or is it more of a mailbox thing?
  • [23:50:24] <russ> would PIO only be ok?
  • [23:50:37] <Downix> PIO wouldn't be, sadly
  • [23:50:50] <russ> wow, you are pretty screwed
  • [23:50:57] <Downix> and it is a normal network device, just customized for a specific app. Ques
  • [23:51:02] <Downix> Queues
  • [23:51:30] <Downix> Well, the other option is to use an ARM w/ PCIe already, but then it's finding a good mobile gpu for it that isn't too power hungry
  • [23:51:32] <russ> I would get an fpga with PCIe support with a SRAM
  • [23:51:51] <russ> hmmm...FPGA+SRAM is not low on the power usage
  • [23:51:57] <Downix> right
  • [23:52:03] <russ> is it a wireless thing?

  • [23:53:10] <Downix> they don't give me much details other than the network speed and that it uses a minicard
  • [23:53:28] <Downix> same cards you'd find in a notebook for 3G or WiFi

  • [23:56:01] <Downix> Believe so, yes
  • [23:56:06] <Downix> I'll double check
  • [23:56:14] <Downix> yes, 1.x
  • [23:56:49] <russ> hmm..so you'd need the omap3 to support a 1.25GHz full duplex serial link
  • [23:58:01] * Openfree (n=Openfree@222.65.175.96) has joined #beagle
  • [23:58:05] <Downix> right, or an OMAP4, not tied to any particular arch, I just happen to like the 3
  • [23:58:44] <mru> and there's no omap4 to be had yet...
  • [23:59:20] <russ> does the omap3 support serial link speeds up to 1.25GHz?
  • [23:59:35] <Downix> dunno, digging through the docs
  • [23:59:51] <russ> and does it support LVDS natively, or would you need an external chip?
