**** BEGIN LOGGING AT Mon Jun 13 02:59:57 2011
Jun 13 03:06:10 <MrCurious> persia: are you around?
Jun 13 03:07:04 <MrCurious> i think it was you who reccomended that i use the ubuntu opencv linraries (from apt-get) rather than building them myself.  do you know if for pandaboard, the ubuntu opencv libraries have any DSP or 3d optimizations in them
Jun 13 03:07:23 <Martyn> they do not, that I am aware of
Jun 13 03:07:36 <MrCurious> curses!
Jun 13 03:09:12 <MrCurious> wonder if anyone is working on hardware acceleration for opencv on pandaboard
Jun 13 03:09:16 <Martyn> Well, there isn't all that much in there to help with accel
Jun 13 03:09:32 <Martyn> It's not exactly like you can use CUDA on an omap 4400
Jun 13 03:10:06 <Martyn> openCL maybe?
Jun 13 03:10:34 <Martyn> that uses the SGX accel
Jun 13 03:13:01 <MrCurious> looks like opencl has not yet come to the pandaboard
Jun 13 03:14:14 <MrCurious> hmmm OpenCL implementation is in work at this time and from what I understand it
Jun 13 03:14:15 <MrCurious> will likely be made available in 2H11. Andrew is at Imagination Technologies
Jun 13 03:14:15 <MrCurious> ( the graphics IP vendor for OMAP4 SoC)  i.e, he has access to the inside
Jun 13 03:14:15 <MrCurious> implementation he he is able to do such posts.
Jun 13 03:14:42 <MrCurious> wonder what 2H11 means?
Jun 13 03:14:50 <MrCurious> 2nd quarter 2011
Jun 13 03:20:11 <MrCurious> http://withimagination.imgtec.com/news/powervr-sgx-cores-get-opencl-conformance/
Jun 13 03:22:28 <MrCurious> looking like you are right about opencl
Jun 13 03:22:36 <MrCurious> its just a question of can they be had
Jun 13 04:17:51 <persia> MrCurious, I don't know of anyone working on optimisation of OpenCV (except perhaps you).
Jun 13 04:21:32 <MrCurious> i am not working on, just inventorying what is available to me
Jun 13 04:22:55 <MrCurious> i am curious if anyone has a pandaboard and a web cam(running ubuntu or android) if they could check teh FPS they get with mplayer on /dev/video0
Jun 13 04:23:22 <MrCurious> would love to know if i have a less than optimum setup 3 web cams varying 8 FPS to 12 FPS
Jun 13 04:24:03 <persia> Looks like OpenCL isn't really well-supported right now.  There's a khronos-opencl-headers package, but it doesn't seem to be something that has dependencies.
Jun 13 04:24:27 <MrCurious> no library package for those headers?
Jun 13 04:24:56 <persia> Only the nVidia CUDA implementation
Jun 13 04:25:15 <MrCurious> and my guess is that is not meant for pandaboard
Jun 13 04:25:20 <persia> And from what I can tell, that's not being distributed as part of Ubuntu currently.
Jun 13 04:25:23 <persia> Heh, no.
Jun 13 04:26:58 <persia> The headers are from http://www.khronos.org/registry/cl/ , but from what I can tell, it needs N implementation libraries.
Jun 13 04:27:46 <persia> Meaning that there's probably lots of integration and interoperability work to be done as the implementations become available and packages are created.
Jun 13 04:29:23 <persia> For the pandaboard, you'll probably get the fastest throughput with video capture using gstreamer.
Jun 13 04:29:40 <persia> I believe TI has some optimised gstreamer input plugins in their PPA.
Jun 13 04:29:56 <persia> (although I may be mistaken: I haven't tried playing with video in)
Jun 13 04:30:33 <MrCurious> gstreamer... isnt that for working the DSP's?
Jun 13 04:30:48 <MrCurious> not something to speed up USB ports
Jun 13 04:33:15 <persia> gstreamer is an A/V programming framework: I believe that it helps deal with onboard processing once it's come over USB.
Jun 13 04:33:29 <persia> If you think 8-12 FPS is limited by USB, then it probably won't help.
Jun 13 04:36:21 <MrCurious> at this point i am unsure of where its bottlenecked. thats why i seek comparison with other users
Jun 13 04:36:55 <MrCurious> given that my disk was much much slower than gruemaster
Jun 13 04:37:03 <MrCurious> and mine was ssd vs his spinning disk
Jun 13 04:41:21 <MrCurious> panda has gstreamer support?
Jun 13 04:43:56 <persia> Everything has gstreamer support, but TI has some special gstreamer modules to make panda even faster at processing video.
Jun 13 04:44:57 <MrCurious> interesting
Jun 13 04:45:32 <MrCurious> lots of packages come back in a gstreamer search
Jun 13 04:46:45 <persia> Right, but the ones with the panda-specific optimisations are probably those in ppa:tiomap-dev/release
Jun 13 05:01:40 <persia> I *think* you want gst-ducati (but I'm not really sure)
Jun 13 05:04:20 <Martyn> Damnit, I can't get a hold of George in New Zealand
Jun 13 05:04:43 <persia> It's the end of the day there...
Jun 13 05:05:01 <Martyn> yes.. but the earthquake seems to have knocked out phones/cells again
Jun 13 05:05:29 <Martyn> there was a swarm, starting at 1pm (5.5) ending with a pretty solid 6.0 quake at 2:20pm .. it's been a little over two hours
Jun 13 05:10:27 <persia> I seem to have some (sporadic) traffic from .nz hitting my router: I presume the lines are up and congested.
Jun 13 05:12:59 <Martyn> .nz is big enough to be up away from Christchurch
Jun 13 05:13:09 <Martyn> can you tell if there is much (if any) traffic coming from there?
Jun 13 05:13:48 <persia> Nope.  I have insufficient knowledge of the relation between network topology and geography in that region.
Jun 13 05:15:11 <persia> I'm probably currently biased, but I'd presume that a series ending in 6.0 isn't likely to have been catastrophic, although that means nothing in terms of individuals.
Jun 13 05:15:50 <Martyn> Yep, and what's bad is that NZ has many, many buildings that just aren't up to earthquake codes
Jun 13 05:16:07 <Martyn> they happen, and lately frequently, but in the past not very often
Jun 13 05:16:09 <persia> That could make it much worse then.
Jun 13 05:18:44 <Martyn> Can .. of course since the big quake four months ago, there has been a call to up the quality of construction (and shore/replace current structures)
Jun 13 05:18:50 <Martyn> but it's only been four months
Jun 13 05:19:23 <persia> Code compliance requires a generation of buildings, which can be fairly long in places with heritage regulations.
Jun 13 09:26:43 <garagoth> Good morning
Jun 13 09:28:07 <garagoth> I have a problem with mu Natty on BB-xM
Jun 13 09:28:10 <garagoth> (again)
Jun 13 09:28:24 <garagoth> After reboot it does not bring up USB and network
Jun 13 09:31:04 <garagoth> also, bridgedriver (for DSP) seems to be missing...
Jun 13 09:34:25 <garagoth> any hints?
Jun 13 09:34:43 <GrueMaster> What rev beagleXM do you have?
Jun 13 09:35:25 <garagoth> C
Jun 13 09:35:38 <garagoth> it was working before reboot (except dsp)
Jun 13 09:36:02 <GrueMaster> Yep.  Known issue.  We have a new kernel for this.  Give me a sec and I'll paste the link up.
Jun 13 09:36:05 <garagoth> and kernel during startup correctly identifies my board (u-boot does not)
Jun 13 09:36:49 <garagoth> GrueMaster: Is this a second patch for Natty on xM rev B, C then?
Jun 13 09:37:01 <GrueMaster> Yes.
Jun 13 09:37:43 <garagoth> But it started up correctly when I rebooted after headless install... ?
Jun 13 09:38:03 <GrueMaster> https://wiki.ubuntu.com/ARM/OmapNetbook
Jun 13 09:38:17 <GrueMaster> The update is at the bottom of the wiki page.
Jun 13 09:38:31 <garagoth> I powered it off for weekend and it did not start.
Jun 13 09:38:35 <GrueMaster> Instructions are the same for headless.
Jun 13 09:39:15 <garagoth> GrueMaster: Is this the same updated image I applied at hm, thursday or friday, when I reported problems with headless install here?
Jun 13 09:39:48 <GrueMaster> Maybe.  I have lost track, as I had to fly to London for meetings.
Jun 13 09:40:01 <GrueMaster> I can look through the backscroll to check.
Jun 13 09:40:56 <garagoth> Because headless install was failing (no network), then applied your (and rsalveti) patch, went fine, reboot, still all fine... now not fine, after halt & poweroff
Jun 13 09:41:36 <GrueMaster> Odd.  Same kernel or did it revert?
Jun 13 09:42:25 <garagoth> The patch is exactly the same, md5 identical.
Jun 13 09:42:30 <garagoth> Hm, dunno.
Jun 13 09:42:35 <garagoth> Should be the same?
Jun 13 09:42:43 <garagoth> How can I check it?
Jun 13 09:44:41 <GrueMaster> Here is my md5sums:
Jun 13 09:44:41 <GrueMaster> 6b627ef6dbbca9b9f8212a512fcd9561  uImage
Jun 13 09:44:41 <GrueMaster> 1747c4ab2cc6a9d0710207f48666a91d  vmlinuz-2.6.38-8-omap
Jun 13 09:45:28 <GrueMaster> I don't have access to a beagleXM here, so I can't check the kernel signature.
Jun 13 09:45:59 <garagoth> my uImage is different
Jun 13 09:46:52 <garagoth> but I changed boot.script and executed flash-kernel
Jun 13 09:47:43 <GrueMaster> flash-kernel would have changed the timestamp, but nothing else as long as it is using the same vmlinuz.
Jun 13 09:47:53 <garagoth> Hmm!
Jun 13 09:48:11 <GrueMaster> Make sure /boot/vmlinuz links to the vmlinuz updated kernel.
Jun 13 09:48:24 <garagoth> it is.
Jun 13 09:52:49 <garagoth> and flsh-kernel generated uImage with md5 2fb0dd0f4061e4b5c0ff482639d69248
Jun 13 09:54:05 <GrueMaster> I don't know what to tell you off hand.  maybe rsalveti will have some ideas.
Jun 13 09:54:34 <garagoth> what is the kernel module responsible for usb on BB-xM ?
Jun 13 09:55:35 <GrueMaster> Not sure, but I know that it is built in.
Jun 13 09:55:42 <garagoth> ahm.
Jun 13 09:56:46 <garagoth> Then maybe you know something about missing bridgedriver module?
Jun 13 09:57:48 <GrueMaster> Not offhand.
Jun 13 09:58:29 <garagoth> Mm. Thanks.
Jun 13 09:58:39 <GrueMaster> Let me see if my beaglexm is still running at home.  If so, I can do a quick test of this kernel.
Jun 13 09:59:09 <garagoth> Sure.
Jun 13 10:04:37 <garagoth> Angstrom boots fine, so not a hardware issue...
Jun 13 10:11:37 <garagoth> GrueMaster: Also, u-Boot still reports Beagle unknown rev 0x02, while u-Boot from Angstrom displays Beagle xM. Kernel displays correctle as bb-xm rev C...
Jun 13 10:12:17 <garagoth> Grr. Why I always make a typo in correctly and usually in typo ...
Jun 13 10:13:46 <GrueMaster> Yes, I don't know if u-boot has been updated upstream yet.
Jun 13 10:14:22 <GrueMaster> Also, I can't get the kernel to work properly with networking either on my older XM, so definately a kernel issue.
Jun 13 10:14:33 <GrueMaster> rsalveti:  ^^^
Jun 13 11:34:28 <garagoth> rcn-ee: How is your work on 2.6.39 kernel for natty?
Jun 13 11:38:33 <jussi> Does anyone know about the driver for the HDMI expansion card on the freescale iMX53 quick start board? (ie. which driver it is)
Jun 13 12:37:42 <rcn-ee> garagoth, haven't been able to repeat it, tried a bunch of mmc cards, haven't been able to get the mmc -110 on the current image..
Jun 13 12:38:21 <garagoth> rcn-ee: Also, your latest 2.6.39.1-x1 kernel fails to bring up my USB devices & network interface...
Jun 13 12:38:53 <rcn-ee> are you using my u-boot?
Jun 13 12:38:55 <garagoth> I installed it on natty headless because 2.6.38-8 has same problem
Jun 13 12:39:05 <garagoth> rcn-ee: Not sure...
Jun 13 12:39:31 <rcn-ee> android people where running the same issue.. if you don't have a u-boot that knows about the xM C, for some reason the usb is dead..
Jun 13 12:40:00 <garagoth> Funny thing is...
Jun 13 12:40:44 <garagoth> that I installed headless natty (after installing patched 38-8 kernel), rebooted, all was fine... then I powered it off, waited 2 days, powered on and no USB
Jun 13 12:44:13 <rcn-ee> so either, something was setup that got lost between reboot's, or the kernel changed..
Jun 13 12:45:10 <garagoth> Kernel was the same...
Jun 13 12:45:48 <garagoth> But few reboots it was working. It stopped after power off
Jun 13 12:45:56 <garagoth> for few reboots*
Jun 13 12:46:59 <rcn-ee> humm strange.. well got to run to work, will be back in just a bit..
Jun 13 12:47:05 <garagoth> Mm.
Jun 13 12:50:38 <garagoth> Ok. More strange things
Jun 13 12:51:27 <garagoth> I booted Angstrom (it booted fine, all USB working), then reset (without powering off), swapped cards, booted ubuntu... and all is working again...
Jun 13 13:48:29 <garagoth> rcn-ee: Let me know when you will be back, I need to learn about your uBoot
Jun 13 13:49:43 <rcn-ee_at_work> garagoth, nothing special, i just build it from angstrom's..
Jun 13 13:50:39 <garagoth> Ok... how to install it? It is "special" as it works...
Jun 13 13:51:39 <rcn-ee_at_work> on your fat partition, just copy it as is. "uboot.bin" would upgrade it.. MLO/X-loader it's usualy a toss up 50/50 you'll need to redo the sd card..
Jun 13 13:56:09 <garagoth> what would it upgrade?
Jun 13 14:06:17 <garagoth> Maybe I will just copy MLO & u-boot.bin from Angstrom? Will it work, or your files have something better/Ubuntu specific?
Jun 13 14:15:54 <GrueMaster> I would hope that we all are using the same u-boot source tree, instead of one for ubuntu, one for Angstrom, etc.  Our released package may be dated, but we should be using the same upstream source.
Jun 13 14:18:10 <rcn-ee_at_work> they are 2011.02 with a few patches: http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/u-boot/u-boot_git.bb?h=2011.03-maintenance#n28
Jun 13 14:53:59 <garagoth> rcn-ee: None of your u-boot.bin files correctly identified my board
Jun 13 14:54:18 <garagoth> while Angstrom u-boot.bin identifies it correctly.
Jun 13 14:54:43 <garagoth> I was checking inages from here: http://rcn-ee.net/deb/tools/beagleboard/
Jun 13 14:55:19 <rcn-ee_at_work> yeah, sorry those are pure mainline was using them to find a mmc card issue on an old Bx...
Jun 13 14:55:25 <rcn-ee_at_work> for the xM: http://rcn-ee.net/deb/tools/UBOOT/u-boot-beagleboard-2011.02+r75+gitrc7977858dcf1f656cbe91ea0dc3cb9139c6a8cc8-r75.bin
Jun 13 14:55:56 <garagoth> ok, let me try....
Jun 13 14:56:12 <rcn-ee_at_work> (that's one i built from angstrom's tree and uploaded)
Jun 13 14:56:50 <garagoth> Original Angstrom u-boot.bin file is looking for /boot/uImage from mmc device 0:2
Jun 13 14:57:16 <garagoth> does your look for /uImage on mmc 0:1 ?
Jun 13 14:58:13 <rcn-ee_at_work> no, i redirect it with: http://elinux.org/BeagleBoardUbuntu#boot.scr_-.3E_uEnv.txt  (on my demo images... )
Jun 13 14:59:50 <brendand> is there a way to get flash working on pandaboard?
Jun 13 15:02:00 <garagoth> mmc0: unrecognised SCR structure version 6
Jun 13 15:02:05 <garagoth> mmc0: error -22 whilst initialising SD card
Jun 13 15:02:19 <garagoth> mmc_erase: erase error -110, status 0x800
Jun 13 15:02:25 <garagoth> end_request: I/O error, dev mmcblk0, sector 334793
Jun 13 15:02:37 <garagoth> This is on your 39.1-x1 kernel
Jun 13 15:04:35 <rcn-ee_at_work> I'd really test another mmc card.. i might have the same one that came from beagle here at work.
Jun 13 15:33:46 <garagoth> rcn-ee: This is different card.
Jun 13 15:34:03 <garagoth> Transcend microsd
Jun 13 15:34:06 <garagoth> 4GB
Jun 13 15:34:21 <garagoth> but there is only one such error and system boots up
Jun 13 15:34:41 <garagoth> on stock card there were hundreds of those...
Jun 13 16:03:27 <garagoth> rcn-ee: On 2.6.38-8 kernel there are no such errors.
Jun 13 16:04:38 <garagoth> and there seems to be some error with usb0 (network) - interface is up, bot not communication goes through. On 2.6.38-8 all is fine again.
Jun 13 16:06:09 <garagoth> but your u-boot works.
Jun 13 16:06:29 <rcn-ee_at_work> garagoth, the only error i'm getting so far is: "mmc0: unrecognised SCR structure version 10, mmc0: error -22 whilst initialising SD card" but i believe that's related to the expansion mmc setup (it doesn't find it)
Jun 13 16:07:54 <garagoth> What can I say.
Jun 13 16:09:11 <rcn-ee_at_work> the one big difference between my 2.6.39 and the older 2.6.38 is we know have support for this mmc based device: http://boardzoo.com/product_info.php?products_id=1
Jun 13 16:10:31 <garagoth> Beagle wlan adapter?
Jun 13 16:10:46 <rcn-ee_at_work> same wlan as on the panda
Jun 13 16:11:23 <GrueMaster> beagle has wlan?
Jun 13 16:11:58 <rcn-ee_at_work> expansion
Jun 13 16:12:51 <GrueMaster> ah.
Jun 13 16:20:30 <rcn-ee_at_work> garagoth, i had one of the mmc card's that came with a beagle xm, but i can't even write an image to it without that task hanging at the moment.. here's my pastebin with a good working card: http://paste.ubuntu.com/625969/
Jun 13 16:22:01 <garagoth> Hm, looks like you have different xM revision
Jun 13 16:22:20 <garagoth> Mine is: [    0.149444] OMAP3 Beagle Rev: xM C
Jun 13 16:22:34 <rcn-ee_at_work> yeah in the lab here i only have my "xM B" labeled, my C is out in the field with another engineer..
Jun 13 16:27:24 <NCommand1r> rsalveti: did you file a bug on the OMAP3/4 boards failing to reset with the new images?
Jun 13 16:27:56 <rsalveti> NCommand1r: nops, as I didn't test with the new images yet
Jun 13 16:28:47 <NCommand1r> rsalveti: well I haven't built a new image yet (and the old images are sitll pre-install, but I'm working on it)
Jun 13 16:30:42 <GrueMaster> NCommand1r: what reboot failure?
Jun 13 16:30:50 <GrueMaster> On oneiric?
Jun 13 16:31:20 <NCommand1r> GrueMaster: when you boot a panda with a partition formatted with the new mkdosfs patch, the reset button onthe panda stops working
Jun 13 16:31:38 <GrueMaster> Ah.
Jun 13 16:32:01 <GrueMaster> I wonder if it is similar to the toolchain issue with the omap3 kernel and usb?
Jun 13 16:32:40 <GrueMaster> bug 791552
Jun 13 16:32:40 <ubot2> Launchpad bug 791552 in linux "No USB support on beagle/beagleXM" [High,New] https://launchpad.net/bugs/791552
Jun 13 18:45:21 <NCommand1r> rsalveti: is three a packaging for x-loader/u-boot? I need to create udebs
Jun 13 19:59:41 <rsalveti> NCommand1r: yup, for both
Jun 13 20:00:37 <rsalveti> NCommand1r: why do you need udeb for them?
Jun 13 20:10:25 <NCommand1r> rsalveti: for d-i
Jun 13 20:36:47 <garagoth> Hmm. I have Beagle-xM trainer board from tin can tools. u-boot correctly detects it.
Jun 13 20:37:06 <garagoth> But, when ubuntu boots, I cannot see i2c bus 2
Jun 13 20:37:11 <garagoth> only 1 and 3 are visible
Jun 13 20:37:20 <garagoth> any hints?
Jun 13 20:37:55 <garagoth> (Angstrom boots and sees i2c bus 2 out of the box and I am able to communicate on it. So not a hardware issue)
Jun 13 20:44:15 <rcn-ee_at_work> garagoth, i don't think ubuntu's kernel has support for any of the expansion board's..  (the patches angstrom have come with haven't been pushed to mainline either..)
Jun 13 20:44:43 <garagoth> but i2c bus 2 is available on expansion port
Jun 13 20:45:03 <garagoth> beagle trainer board just translates voltage levels
Jun 13 20:46:39 <rcn-ee_at_work> only 1 & 3 are visable because port 2 isn't setup in ubuntu or mainline either: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=arch/arm/mach-omap2/board-omap3beagle.c;h=7f21d24bd437732724a45af9302c50a514f56482;hb=HEAD#l418
Jun 13 20:48:02 <rcn-ee_at_work> for the expansion boards you need a patch similar to this: https://github.com/RobertCNelson/stable-kernel/blob/master/patches/sakoman/2.6.39/0032-OMAP3-beagle-add-support-for-expansionboards.patch
Jun 13 20:48:51 <garagoth> Just great...
Jun 13 20:49:25 <garagoth> Thanks. will think over it tomorrow. It is already 11 PM here. I need to sleep...
Jun 13 20:49:34 <garagoth> Cheers!
Jun 13 20:49:40 <garagoth> and good night...
Jun 13 23:33:54 <Jef91> Anyone know if Ubuntu ARM is fully functional on the apple TV box?
Jun 14 00:41:01 <cipher> does anyone know the latest "start on" type upstart stanza one could use to start an executable/script?
Jun 14 00:41:17 <cipher> latest in terms of time since boot
Jun 14 00:42:17 <cipher> I have a specific issue where the daemon I'm trying to start depends on a fully booted system being ready to go and "start on runlevel [2345]" doesn't seem to be good enough, requiring me to restart my process before it works correctly
Jun 14 00:42:55 <cipher> the process is dependant on modprobe of a linux gadget and setting of permissions for the led in /sys/class/leds
Jun 14 00:53:09 <persia> cipher, Don't do that in upstart.  Have udev start your service when it detects the device (hotplug)
Jun 14 01:45:21 <cipher> persia: unfortunately udev doesn't detect it, at least when I use udevadm to monitor there's no event for my device
Jun 14 01:45:27 <cipher> because it's a platform device, methinks
Jun 14 01:46:19 <persia> There's a bug there somewhere.
Jun 14 01:46:42 <persia> If you need to modprobe, then it *should* provide an event.
