  12. [10:53:55] <Gelmi> hello
  13. [10:55:13] <Gelmi> i have a question - is there the easy way to write, build and load a simple 'blinking led' program to PandaBoard?
  14. [10:55:55] <Gelmi> without using OS like Ubuntu, Android etc?
  15. [10:56:56] <Gelmi> I usually develope embedded software in eclipce+codesourcery+jlink
  16. [11:05:40] <dm8tbr> the pandaboard is not intended for bare-metal use
  17. [11:05:51] <dm8tbr> so booting at least a kernel is recommended
  18. [11:06:41] <dm8tbr> you can just put an 'while true do; echo 1 >/sys/some/foo/bar; sleep 1; done' in your initramfs
  19. [11:07:16] <Gelmi> ok thx
  20. [11:08:34] <Gelmi> and is there a way to buy a single OMAP 4 chip? if for example this one on PB brake?
  21. [11:09:14] * gxben (~gxben@2a01:e35:8b11:d200:f2de:f1ff:fe63:7ede) has joined #pandaboard
  22. [11:11:10] <dm8tbr> you can buy 1M omap4 chips from TI
  23. [11:11:18] <Gelmi> :) ok
  24. [11:12:26] <dm8tbr> also I doubt if you're concerned about one chip you'd have the necessary BGA rework kits
  25. [11:16:08] <phdeswer> Gelmi, if you're more into leds and stuff without OS your pandaboard and the omap4 might be grossly overpowered. A cortex M microcontroller like in the ST32 line might be more suitable
  26. [11:16:59] <dm8tbr> I hope he just wants to get a start and has bigger plans, else I'd have probably said so too
  27. [11:17:50] <Gelmi> yes, of course
  28. [11:18:19] <Gelmi> I have plans to write cery big tutorial in Polish
  29. [11:18:58] <Gelmi> and I was wondering if I should write how to compile and load simple programm without OS
  30. [11:19:40] <Gelmi> but I think it will be better to write how to write simple programm on Ubuntu for instance

  61. [13:24:34] <dan_84a> hey i just managed to get Angstrom up and running on my pandaboard, but there is no networking? Any ideas?
  62. [13:26:17] <cromega> wired or wireless?
  63. [13:26:35] <dan_84a> neither
  64. [13:26:52] <dan_84a> wired im trying for now tho
  65. [13:27:39] <dan_84a> i have used the online builder to get the rootfs
  66. [13:31:17] <cromega> cant you see the usb0 interface at all?
  67. [13:33:14] <dan_84a> there is nothing other than loopback in ifconfig

  72. [13:38:54] <cromega> try to bring up the interface
  73. [13:39:20] <dan_84a> figured it, i added auto usb0 and dhcp to the interfaces and up it came

  97. [15:39:50] <fairbanks> Hi everyone
  98. [15:40:20] <Alison_Chaiken> Hi fairbanks.
  99. [15:40:21] <fairbanks> the correct name of the SD/MMC card in the pandaboard A2 is mmcblk0p2 ?
  100. [15:40:35] <fairbanks> hi Alison_Chaiken
  101. [15:40:40] <topfs2> RichiH, no support written to directly use iva-hd, I have code made for h264 and gstreamer though
  102. [15:45:23] <asgaroth1> Hey there!
  103. [15:46:24] <fairbanks> I cannot get boot the pandaboard.. onces it worked but not anymore ! .. it just drop to shell ( ALERT! /dev/mmcblk0p2 does not existe)
  104. [15:46:25] <asgaroth1> trying to cross compile using the instructions here http://www.omappedia.com/wiki/PandaBoard_L27.10.2-P1_Release_Notes
  105. [15:47:10] <asgaroth1> it works but usb or in specific the usb mouse and touchscreen does not work
  106. [15:47:38] <asgaroth1> we tried the cherry picking of the rowboat
  107. [15:47:56] <asgaroth1> but the first pick doesn't give something like "x files changed" or something
  108. [15:48:00] <asgaroth1> only
  109. [15:48:16] <asgaroth1> Finished one cherry-pick.
  110. [15:48:20] <asgaroth1> # Not currently on any branch.
  111. [15:48:24] <asgaroth1> nothing to commit (working directory clean)
  112. [15:48:27] <asgaroth1> is this still right?
  113. [15:48:35] <asgaroth1> the other cherry picks have a different output
  114. [15:48:51] <RichiH> topfs2: i.e. not ready for prime time, yet?
  115. [15:49:05] <Alison_Chaiken> fairbanks, on my formatted sdcard, mmcblk0p2 is correct, with mmcblk0p1 being /boot. Do you have mmcblk0p1? Can you stop uboot and have it list info about the card, or doesn't uboot come up at all? If uboot isn't coming up, it's mmcblk0p1 that has a problem.
  116. [15:49:26] <Alison_Chaiken> What the partitions will be called is set when you format the card, IIRC.
  117. [15:50:16] <topfs2> RichiH, far from it. It works to use but only one dev (me) has panda atm and I'm kindof preoccupied elsewere
  118. [15:50:30] <topfs2> any patches towards iva-hd and such is more than appreciated though
  119. [15:51:02] <RichiH> topfs2: lack of a pandaboard and time precludes me from helping, sorry
  120. [15:51:04] * thaytan (~jan@CPE-124-183-182-124.lns17.ken.bigpond.net.au) Quit (Ping timeout: 250 seconds)
  121. [15:51:56] <topfs2> yes, it usually does
  122. [15:55:39] <fairbanks> thanks /notice Alison_Chaiken, this is the output of the editenv
  123. [15:55:49] <fairbanks> http://pastebin.pandaboard.org/index.php/view/73766067
  124. [15:57:43] <fairbanks> it actually boots but It stays stuck after booting the kernel
  125. [15:57:48] <fairbanks> then it drops to shell
  126. [15:59:08] * tomeff (~Adium@ip-78-45-50-45.net.upcbroadband.cz) has joined #pandaboard
  127. [15:59:17] <Alison_Chaiken> What shell does it drop to? The console? What the last message you see, the kernel boot message?
  128. [16:01:36] <Alison_Chaiken> When I had symptoms similar to yours (boot started, wouldn't read mmcblk0p2), it turned out to be because I wasn't using a high-current transformer. A 2A transformer didn't have enough juice to read mmcblk0p2, only mmcblk0p1. If you have a 2 or 3 A transformer and have USB devices plugged in to your board without auxiliary power, that could be your problem.
  129. [16:03:08] <fairbanks> i am using a 5V 4A power supply with only usb keyboard attached
  130. [16:03:27] <fairbanks> I am posting a photo of the last screen ...
  131. [16:08:49] <fairbanks> this is the last screen I see on the HDVI screen ... www.flickr.com/photos/rumbosalaire/5825070250/
  132. [16:13:04] <Alison_Chaiken> Hmm, so you have a kernel but not a root file system, or the ramdisk? That's odd. If you put the SDcard in an external reader and mount it, do you see both mmcblk0p1 and mmc0blkp2?
  133. [16:15:30] * dan_84a (~dan@cpc1-stap11-2-0-cust499.12-2.cable.virginmedia.com) Quit (Quit: This computer has gone to sleep)
  134. [16:16:42] <fairbanks> I see 2 patition .. /dev/sdb1 and /dev/sdb2 (the first one of 75MB and the second 2.44GB)
  135. [16:17:29] <fairbanks> /dev/sdb1 contains the boot.scr , MLO and so on ..
  136. [16:18:09] <fairbanks> /dev/sdb2 contains the folders bin, boot, dev, etc, ...
  137. [16:30:35] <Alison_Chaiken> Hmm fairbanks, I'm kind of stumped. Sounds like you're doing everything right. What's the last message before BusyBox? Any chance your filesystem type is not ext3 and so mount is failing for that reason?
  138. [16:34:19] <lill> fairbanks: which bootargs do you use?
  139. [16:36:09] <fairbanks> Alison_Chaiken, on the terminal I only see..uncompressing linux ...booting kernel then on the hdmi I see the ubuntu screen charging on....after maybe 15 seconds lataer it drops to the shell
  140. [16:36:37] <fairbanks> lill - how can I know which bootargs am I using
  141. [16:37:09] <fairbanks> btw ... before using zcat to download the image on the sd card I format the sd card as fat32, should I use ext3 ?
  142. [16:37:31] <lill> first partition fat32, second ext3
  143. [16:37:42] <Alison_Chaiken> Hmm, so Ubuntu starts and then fails. So your filesystem is mounting then.
  144. [16:38:03] <fairbanks> i see the ubuntu screen, then it drops to shell
  145. [16:38:22] <fairbanks> only once it worked, i didn't know why !
  146. [16:39:07] <fairbanks> it boot ok and then it install ubuntu very well.. after some minutes i was surfing the web by firefox
  147. [16:39:18] <lill> hm
  148. [16:39:21] <Alison_Chaiken> If you hit ESC when Ubuntu screen comes on, you may be able to go to text screen and read the failure message. And, the really good news is, if syslogd started, you may be able to see helpful info in /var/log/messages if you put your sdcard in another host and look on /dev/sdb2.

  181. [17:34:57] <Alison_Chaiken> And do you have serial console connected?
  182. [17:35:44] <fairbanks> yes I have the serial console
  183. [17:35:52] <fairbanks> let me try to mount the sdb2
  184. [17:38:46] <dm8tbr> fairbanks: what sort of screen do you use?
  185. [17:40:15] <Alison_Chaiken> Aha, found what I was looking for: Hallinan, _Embedded Linux Primer_, p. 394 has instructions on "Dumping the printk Log Buffer."
  186. [17:40:30] <Alison_Chaiken> Bottom line is, grep __log_buf System.map
  187. [17:40:35] <fairbanks> I am using minicom with emulation VT102
  188. [17:41:11] <Alison_Chaiken> The output gives the address where the kernel has written its dmesg.
  189. [17:41:44] <Alison_Chaiken> You can use the md command from Uboot to display what's at that address.
  190. [17:42:51] <Alison_Chaiken> You may need to subtract the KERNELBASE address first.
  191. [17:43:28] <Alison_Chaiken> You should be able to google up more detailed instructions, or maybe even find the text of Hallinan's book, which I totally recommend.

  236. [18:14:15] <dm8tbr> wasn't it that the board should come up in VGA or SVGA if there is nothing connected at first?
  237. [18:14:49] <dm8tbr> there might be some workaround for LG too, but I don't know that, maybe _av500_ knows
  238. [18:16:52] <_av500_> hdmi.c does not like LG edid

  242. [18:18:22] <fairbanks> :P yes
  243. [18:18:48] <fairbanks> i will try to google it a bit or try to catch a borrow hdmi monitor
  244. [18:19:38] <fairbanks> but ... I also was trying to run the headless verion ahd happend the same... anyway ... i will try to run th headless verion with no hdmi screen attached
  245. [18:23:03] <dm8tbr> IIRC it goes into VGA or SVGA if you boot without display connected
  246. [18:23:21] <dm8tbr> so try to boot and only attach the monitor after it has booted
  247. [18:24:20] <fairbanks> ok ok let me see what happens
  248. [18:27:03] <fairbanks> still the same
  249. [18:28:16] <dm8tbr> no idea, could be a faulty board too, but I'd recommend to try clean with a different screen first
  250. [18:29:07] <fairbanks> I will mount the headless version
  251. [18:29:10] <fairbanks> and see what happens

  291. [19:38:07] <fairbanks> and the format of the sd before the omage should be fat32 ?
  292. [19:38:13] <fairbanks> or ext3
  293. [19:43:05] <dm8tbr> irrelevant
  294. [19:43:15] <dm8tbr> the image will overwrite everything

  298. [19:47:38] <drath> are there any /dev/mmcblk* entries?

  309. [19:53:45] <fairbanks> I pluged again the sd card while running initramfs and still nothing
  310. [19:54:16] <drath> is there any sd-card related output in "dmesg" (assuming you can run that from the initrd-shell)?
  311. [19:56:01] <drath> for example my system says: "mmc0: new high speed SDHC card at address e624" "mmcblk0: mmc0:e624 SD08G 7.40 GiB" "mmcblk0: p1 p2"

  373. [23:09:00] <jotschi> Hi
  374. [23:12:39] <GPSFan> Sonicadvance1, this might help: http://focus.ti.com/pdfs/wtbu/swpz009D.pdf
  375. [23:14:37] <jotschi> Can someone explain me why ubuntu and debian have different repositories for their omap4 kernel patches? I just tried the "debian" kernel patch from https://launchpad.net/~beagleboard-kernel as suggested at http://elinux.org/BeagleBoardDebian but audio does not work (as shortly mentioned at the repository page). The ubuntu kernel patch from kernel.ubuntu.com should be working with debian?
  376. [23:28:19] <rcn-ee> jotschi, sorry, i need to redirect that link to github... as to why the audio doesn't work, not sure i've actually tested it probally missing a simple config option, the kernel is pretty close to mainline and that's about it..
  377. [23:30:51] <jotschi> Do you mean the link within the 'Kernel Build' section? Launchpad is therefor obsolete?
  378. [23:31:10] <rcn-ee> yeah, converting the debian page right now. ;)
  379. [23:32:07] <rcn-ee> okay, refresh that section you get the new kernel location.. (i finally completed my tree conversion to git.. and you don't have to register either now..)
  380. [23:37:22] <jotschi> I see. So far your scripts worked very well. I don't see how the kernel config is beeing setup. Guess its the default one for arm architecture?
  381. [23:38:15] <rcn-ee> it's under the patches dir "defconfig" is the default for all...

  385. [23:38:56] <rcn-ee> it gets pulled in when you run "./build_kernel.sh".. that way you always start with a 99% there working config.. (just missing audio on panda i guess)
  386. [23:39:38] <rcn-ee> nothing really seems to be missing from: CONFIG_SND_*_* section..

  388. [23:42:23] <jotschi> I see. I'll compare the config with the debian.ti-omap4/config/config.common.ubuntu (ubuntu config)
  389. [23:43:44] <rcn-ee> yeah i'm looking at that one too..
  390. [23:44:33] * zyga (~zyga@linaro/zyga) Quit (Read error: Connection reset by peer)
  391. [23:48:19] <rcn-ee> ah, that makes sense... mainline is missing: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-natty.git;a=blobdiff;f=arch/arm/mach-omap2/board-omap4panda.c;h=1355d2d0c87fc2648cd13466d9b01ed9d7a4e058;hp=c48a4e16bfdefe25689f717b4f8933d583a1ecc9;hb=577ba65da0ed7d107e43edf94d2eed1d9c805857;hpb=ce58b0522f49f93b27ac1b24257e3370d56e7f32
  392. [23:49:11] <jotschi> That should be included in the kernel patch?
  393. [23:50:11] <rcn-ee> yeah, i need to clone that tree to get the patch, i'll then push out a quick patch to test it..
  394. [23:51:07] <rcn-ee> thinking this: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-natty.git;a=commit;h=577ba65da0ed7d107e43edf94d2eed1d9c805857 and this: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-natty.git;a=commit;h=367b834561194f06b73dfcd298f17936e0d8c597
  395. [23:51:10] <rcn-ee> shoudl do the trick..
  396. [23:54:26] <jotschi> Okay. I can try that once you merged the diff into your repository
  397. [23:58:25] <jotschi> Isn't it hard to keep track of all those changes that are made (for example) in other repositories like the ubuntu one? What is the advantage if you manage your own sets of kernel patches for the omap4? I'm just curious
