  • [03:05:47] <Max_Galemin> dancios: to use DSP for handling all data from camera and send to the ARM ready-to-use video stream (the basic idea)
  • [03:07:26] <dancios> RAW Camera -> DSP(on beagle) -> H.264/MPEG4 -> Lan/Wlan

  • [04:59:42] <rcn-ee> it should have, but i don't think many testers had the hardware, so it could have easily regressed..
  • [05:00:09] <pacman_> So after I boot the module mt9t112 is loaded in the kernel.
  • [05:01:07] <pacman_> Kernel command line (this is the validation image) contains camera=lbcm3m1
  • [05:01:43] <pacman_> I also get the line Beagle cameraboard: lbcm3m1
  • [05:02:21] <pacman_> Later I get the line Beagle cameraboard: registering i2c2 bus for lbcm3m1
  • [05:03:50] <pacman_> I also get a "Division by zero in kernel" exception... fun.
  • [05:03:57] <Max_Galemin> pacman: I'm not sure, but try to enable this in the kernel:

  • [05:06:40] <rcn-ee> well, i'm assuming there's some kinda of i2c device on that image board, start by scaning that i2c port with the tools to see if you can find an address..
  • [05:08:25] <rcn-ee> it's been a while, but 'i2cdetect -l' list bus's and then i2cdetect (bus)... it might help debug why your module isn't working with the image..
  • [05:09:05] * russ (foobar@ip70-176-251-1.ph.ph.cox.net) has joined #beagle
  • [05:10:18] <pacman_> On the validation image: i2cdetect -l lists 3 busses i2c-1, i2c-2, i2c-3
  • [05:10:34] <rcn-ee> 2 should be your dvi port..
  • [05:11:17] * GPSFan (~kenm@64.92.145.112) Quit (Remote host closed the connection)
  • [05:11:32] <pacman_> ic2detect i2c-x gives me some ranges with -- and UU in them.
  • [05:12:08] <pacman_> i2c-3 is all "--"
  • [05:12:14] <rcn-ee> actually dvi is port 3... just do "ic2dectec 1 or 2"
  • [05:12:26] <pacman_> ic2-1 has some "UU" and so does i2c-2 (just one pair).
  • [05:12:43] <pacman_> Port 3 is not connected (no display on my BB right now) so that jives with what I'm seeing.
  • [05:13:08] <pacman_> dmesg spew says camera allocated bus 2 and there are addresses there.
  • [05:13:37] <pacman_> I have to use i2cdetect -r <bus#> or it complains (BTW)
  • [05:13:42] <rcn-ee> yeah, bus 2 should be the expansion area.. bus 1 just has the twl4030
  • [05:14:35] <rcn-ee> yeah, i'm a little rusty on i2c, haven't probed it since we did the pico dlp video..
  • [05:15:27] <pacman_> OK, so when I get the address (i2c-2, address 0x3c) then I run i2cdump 2 0x3c I get "device or resource busy" which would jive with having the module loaded.
  • [05:16:21] <pacman_> Removing the camera module, then allows me to do an i2cdump at the address i2c-2/0x3c
  • [05:16:45] <pacman_> I mean removing the camera module from the kernel... the camera is (of course) still connected to the board /w nice happy green light.
  • [05:17:10] <rcn-ee> of course... so it's probally working then..
  • [05:17:35] <pacman_> I get 'something" back as data from the dump. (i.e. it is not all zeros/ones, etc.)
  • [05:18:08] <rcn-ee> it's probally just all the registers..
  • [05:18:16] <pacman_> Right.

  • [05:23:51] <rcn-ee> probally got lucky with the fatfs on the 'one' card.. the onboard bootrom can be pretty picky..
  • [05:24:40] <pacman_> There is the 'zero out the first sector' trick that is sometimes needed (I understand). I think they have instructions over at omappedia for 'preparing the flash card'
  • [05:25:08] <pacman_> Basically you dd a bunch of zeros into the first sectors of the card because somehow fdisk doesn't 'clear out' enough from some cards to make the bootloader happy.
  • [05:26:06] <pacman_> http://www.omappedia.org/wiki/Minimal-FS_SD_Configuration
  • [05:26:19] <Joe> does that have to do with the SD card hardware itself or is it the way that its is formatted with software?
  • [05:26:54] <pacman_> I don't know exactly. It might just be how manufacturers format things assuming that everyone in the world is running Windows, etc.
  • [05:26:55] <rcn-ee> usally the format of the first partition... What tools are you usuing?

  • [05:28:17] <cwillu> make sure you don't have any stray non-8.3 filenames in the root of the fat partition, that will definitely break the boot
  • [05:28:28] <pacman_> I've always followed the Omappedia instructions for the card formatting and I have a SanDisk 4GB, a couple of other 2GB and 8GB from different folks that all work.
  • [05:28:51] <pacman_> Yeah. I just have the "3 files" MLO u-boot.bin uImage

  • [05:33:46] <cwillu> no :(
  • [05:33:54] * Mike is now known as Guest35470
  • [05:34:00] <rcn-ee> well they are cheaper... and i have a 1Ghz patch you can stress test..
  • [05:34:04] <cwillu> heh
  • [05:34:16] <cwillu> to be honest, I'm more interested in the pandaboard :)
  • [05:34:34] <cwillu> dual hdmi out ftw!
  • [05:34:37] <rcn-ee> did you get your order in yet?
  • [05:34:38] <pacman_> I can see that, although it is quite a bit bigger.
  • [05:34:56] <cwillu> if I wanted small, I'd be using overo
  • [05:35:08] <pacman_> Heh. I've been on the wait list since the 1st day for panda. No board.
  • [05:35:33] <rcn-ee> well the first uints are shipping this week.. ;)
  • [05:35:51] <pacman_> They *always* say that 8>
  • [05:36:06] <cwillu> uint=?
  • [05:36:12] <cwillu> oh, units
  • [05:36:14] <pacman_> Well maybe a ushort
  • [05:36:36] <rcn-ee> (i can't spell today..) pacman_ no, they are actually shipping, got mine yesterday..
  • [05:36:53] * cwillu nelson HAHA's
  • [05:36:59] <pacman_> That is good news.
  • [05:37:05] <pacman_> That they are shipping soon.
  • [05:37:41] <rcn-ee> pacman_, did you remember what day you ordered? i was on the 18th..
  • [05:38:09] <pacman_> 19th at 12:12AM
  • [05:38:35] <rcn-ee> your in good shape then..
  • [05:38:38] <pacman_> OK. so my fancy new Angstrom image booted up (looking at the camera issue)
  • [05:38:51] <rcn-ee> did the camera come up/
  • [05:39:16] <pacman_> Well, I have no /dev/videoX?
  • [05:39:50] <pacman_> Checking the I2C again..
  • [05:40:27] <rcn-ee> crazy, you'd think someone would have documented that setup.. you might just have to ping the beagleboard group, maybe some not on irc knows the secret sauce..
  • [05:41:53] <pacman_> Right... Koen has the pictures of it working and it 'seems' to be there. I could have a hardware problem since I don't have two units to compare.
  • [05:41:58] <pacman_> Dunno.
  • [05:42:46] <pacman_> I notice that no v4l anything shows up in modules.
  • [05:43:10] <pacman_> Perhaps I need to get the remainder of the modules on the system and 'forcibly modprobe' something?
  • [05:43:52] <rcn-ee> maybe, are the modules for your current kernel not present?
  • [05:44:22] <pacman_> Well a small set of modules are in /lib/modules/2.6.32... not what I would expect to see on a desktop machine (for instance)
  • [05:44:42] <rcn-ee> on the angstrom demo page, they are a seperate download..

  • [05:46:23] <pacman_> No other related modules either.
  • [05:47:02] <pacman_> The string 'v4l' does not appear in my built Angstrom modules-xxxx.tgz tarball as a name.

  • [05:57:42] <pacman_> What is holding you up about it?
  • [05:58:25] <donP> i try to sudo iwlist wlan0 scan
  • [05:58:44] <donP> interface does not support scanning
  • [05:59:10] <pacman_> OK, so this is a USB wi-fi dongle that gets recognized by the kernel?
  • [06:00:04] <donP> yeah when i iwconfig I get
  • [06:00:31] <donP> IEEE 802.11bgn ESSID:off/any
  • [06:00:47] <donP> so i nano /etc/network/interfaces
  • [06:00:57] <donP> add

  • [06:11:45] <pacman_> donP: I've never tried one of the dongles with a real key. Sometimes things like WPA-2 require you to set up wpa-supplicant, etc/
  • [06:12:09] <pacman_> Can you try it on an 'open' network just to make sure the rest of the mechanics are working? I probably don't have better advice. Sry.
  • [06:12:23] <donP> also tried iwconfig wlan0 essid Linksmoke key XXXXXXXX
  • [06:12:25] <donP> right on
  • [06:12:31] <donP> ill give that a shot
  • [06:13:29] <pacman_> As for the Leopard imaging camera: Camera 2, pacman_ 0: No dice. Basically I get the same results with the validation image and my freshly built Angstrom image.
  • [06:14:33] <donP> dongles a usb wifi card?

  • [06:14:52] <pacman_> Yes that is what I meant.
  • [06:20:00] <tdh2002> I use tp-link WR541, it can work.
  • [06:20:56] <tdh2002> no, thisi one : 54M TL-WN321G+
  • [06:21:27] <pacman_> Yeah. Sometimes it depends on the dongle and how good the driver is for it. I've had more problems with the 'security' features than getting just basic unsecure wifi working.
  • [06:25:34] <donP> when i iwconfig wlan0 essid Linksmoke , then iwconfig I can see the essid is set to Linksmoke but if i ifconfig I never get an ip
  • [06:25:41] <donP> secure and unsecure
  • [06:25:48] <donP> prob the card
  • [06:25:57] <donP> i got the cheapest one they had
  • [06:26:28] <pacman_> Well if it is associated, then try something like dhclient wlan0 and see what you get.
  • [06:27:21] <pacman_> Basically just try to get it working from the command line with a manual iwconfig and dhclient and then fix up the scripts later to make it automatic.

  • [06:32:15] <donP> yes
  • [06:33:48] <pacman_> If you know your general subnet configuration you could just 'force it'... Oh, which reminds me... The Ubuntu "Network Manager" thing is disabled, right?
  • [06:34:35] <pacman_> I've not used an Ubuntu beagleboard setup in a while. Does it have Netowrk Manager (up in the icon bar on the right)? That thing 'owns' your network configurations and unless you disable it, you can't really 'experiment' at the command line reliably.
  • [06:35:03] <pacman_> Have to head out. Good luck.

  • [11:28:24] <koen> and since x-load is an old uboot you should be able to 'port' it
  • [11:28:55] <jacekowski> aholler: then you can make your own uboot
  • [11:29:02] <koen> aholler: http://gitorious.org/spark-sls/x-load
  • [11:29:07] <jacekowski> aholler: hardware is perfectly capable of doing it
  • [11:29:28] <koen> and water is wet
  • [11:29:28] <aholler> jacekowski: i know that the hw includes usb.
  • [11:29:35] <koen> can we stop stating the obvious?
  • [11:29:59] <aholler> koen: thanks
  • [11:31:40] <aholler> yes, in that x-load there is CONFIG_USB_EHCI_OMAP3 and CONFIG_CMD_USB ;)
  • [11:34:36] <koen> aholler: iirc it is 2 commits
  • [11:34:48] <koen> ehci glue and clock config
  • [11:35:11] <koen> at work they were really excitid, but noone took the time to apply it to uboot
  • [11:35:23] <aholler> I've just fetched that u-boot. will try using those patches in u-boot
  • [11:35:36] <aholler> s/that u-boot/that x-load/
  • [11:40:22] <aholler> that one seems to be the one needed: http://gitorious.org/spark-sls/x-load/commit/8a1249700dab3d6a613eb9a15e07dc8a759a1f08
  • [11:41:17] <aholler> at least some of those patches, seems to be mixed up
  • [11:41:34] <aholler> that atag-stuff can't be needed ;)
  • [11:42:04] * ksinkar_ is now known as ksinkar
  • [11:46:09] <koen> aholler: that tree is meant to get rid of uboot
  • [11:46:20] <koen> aholler: so xload loads uimage from usb storage
  • [11:46:51] <aholler> i like u-boot because it offers more than just loading uImage
  • [11:47:23] <aholler> at least when networking is available ;)
  • [11:47:54] <_koen_> I know
  • [11:48:01] <_koen_> jsut saying why it has atag stuff
  • [11:48:03] <aholler> which might be difficult, but maybe the other patch av500 has posted will help there
  • [11:48:37] <aholler> don't know if that is an ehci-network driver
  • [11:49:15] <aholler> but maybe u-boot has such already
  • [11:50:32] <aholler> haven't had the need to usb networking through an usb-dongle with u-boot (other embedded hw normally includes some real eth-hw)

  • [11:56:42] <aholler> again only some parts.
  • [11:57:05] <aholler> those committers don't like to split patches into meaningful parts
  • [11:57:56] <_koen_> aholler: please share patches if you get it working
  • [11:58:43] <aholler> may need some time. I don't need it, so it has low priority ;)
  • [11:58:59] <hitlin37> using softfp object code from two different compilers is problemetic?
  • [11:59:02] <_koen_> this is the latest beagle testing tree: http://gitorious.org/beagleboard-validation/u-boot/commits/koen/beagle-2010.12
  • [11:59:39] <aholler> _koen_: is there something need for the master?
  • [12:01:47] <aholler> I first will try out the master, I assume the master of u-boot should now work with gcc 4.5.1 (for the beagle), haven't tried it lately
  • [12:05:20] <mru> did sakoman's relocation patch go in?
  • [12:06:26] <aholler> arnold has submitted some more versions of his patch for the .lds including armv7
  • [12:07:19] <aholler> will see it in some minutes, just have to switch the sd to one the hw-loader likes
  • [12:08:30] <aholler> networking via bt via usb would be nice too, I've switched from wlan to bt ;)
  • [12:10:35] <aholler> but that's just something never should be done for u-boot, otherwise it would get more bloated and sometimes will replace linux. ;)
  • [12:11:17] * mru thinks u-boot should have a mail reader
  • [12:13:55] * ssvb (~ssvb@net-208.nrpn.net) has joined #beagle
  • [12:14:45] <_koen_> mru: the relocation patch is in
  • [12:15:14] <_koen_> mru: and uboot reading mail would prove jwz right and we don't want to do that
  • [12:15:59] <av500> aholler: nice, your 2nd url has a guy I know as (c) :)

  • [12:17:26] <av500> and he still owes me money....
  • [12:17:29] <aholler> tell him that patch is a pain. just throwing together usb-storage, omap-ehci-driver and such into one patch isn't what the world needs ;)
  • [12:17:40] <av500> aholler: he did not do the patch :)
  • [12:17:52] <dm8tbr> hehe, I know him too
  • [12:17:56] <av500> he wrote one of the 2 usb stacks in linux
  • [12:18:02] <aholler> ah I see
  • [12:18:04] <av500> dm8tbr: ah right
  • [12:18:17] <dm8tbr> met him in f'hafen

  • [12:19:14] <aholler> baycom doesn't tell me anything.

  • [12:19:39] <av500> aholler: ham stuff

  • [13:01:57] <av500> aholler: there was a linker patch for that iirc
  • [13:02:14] <mru> that was uboot
  • [13:02:32] <av500> ah
  • [13:02:34] <aholler> just wanted to ask if x-load is now relocated too ;)

  • [13:04:50] <av500> you forgot sudo

  • [13:05:14] <cwillu_at_work> on the serial header, is tx pin 2 or 3?
  • [13:05:31] * av500 throws the BBSRM at cwillu_at_work

  • [13:08:00] <cwillu_at_work> oooo, smelly!
  • [13:08:10] <aholler> hmm, gcc 4.3.5 and binutils 2.20.1 doesn't seem to produce a working x-load too :(

  • [13:16:39] <av500> probably
  • [13:16:57] <av500> i guess rom code will not init mmc registers if it boots from nand
  • [13:17:06] <av500> so you could check some of them

  • [13:32:02] <aholler> btw. it would be really, really helpful to add urls for the repositories/branches of u-boot/x-load to beagleboard.org, e.g. in Top Projects or better Basic Projects
  • [13:32:17] <av500> its a wiki, no?
  • [13:32:18] <av500> do it :)
  • [13:32:28] <aholler> beagleboard.org?
  • [13:32:46] <av500> i bet it has an easy pwd
  • [13:32:52] <av500> and kridner is on vacation
  • [13:33:12] <aholler> wikis are bad. there should be just one resource which shouldn't be changable by everyone
  • [13:33:24] <aholler> at least for u-boot and x-load.
  • [13:34:09] <aholler> everone seems to have his own favoured repo/branch/commit for those two ;)
  • [13:34:47] <av500> aholler: you know, there is one uboot repo per muxable pin
  • [13:34:57] <sakoman__> aholler: for u-boot the favored repo should be mainline

  • [13:35:26] <sakoman__> for x-load, good luck -- there is no upstream :-(

  • [13:43:04] <aholler> seems to fail too when I compile that
  • [13:43:31] <sakoman__> you must be using a modern binutils :-)

  • [13:45:30] <aholler> looking at the .lds I haven't seen stuff which needs change. at least not that stuff needed for u-boot

  • [13:53:03] <sakoman__> if it is using nand, then something is wrong with the u-boot on mmc
  • [13:53:41] <aholler> how x-load will check that without loading it?

  • [13:54:17] <sakoman__> look at the code starting at line 93
  • [13:54:48] <aholler> does file_fat_read doesn't output something?
  • [13:55:01] <sakoman__> either there is something about the mmc formating that it is unhappy with, or the name is messed up, or ??
  • [13:56:14] <sakoman__> aholler: no, fat_read just fails with an error code, nothing is printed
  • [13:57:12] <aholler> I'll switch to using sam-ba ;)
  • [14:00:07] <aholler> a switch from x-load to git-version would be nice too. all x-load are currently 1.4.4ss ;)

  • [18:12:28] <mru> the onchip rom
  • [18:12:49] <dpc> And what is on this ROM? Can it be flashed or is it solid ROM?

  • [18:13:12] <mru> no changing it without melting the chip
  • [18:13:18] <dpc> Is there any documentation describing the code on this rom?
  • [18:13:31] <dpc> Is it uboot?
  • [18:13:40] <mru> no and no

  • [18:15:00] <dpc> I'm quite a n00b with a new -mx on my desk.
  • [18:15:44] <mru> rom loads x-loader from the sd card
  • [18:15:56] <mru> x-loader loads u-boot, also from sd
  • [18:16:00] <aholler> there is some description in the trm
  • [18:16:27] <dpc> OK. So it has the code to use SD? Anything else that it can do?

  • [18:18:43] <av500> rom code can boot any code from sdcard

  • [18:19:20] <av500> Ceriand|work: err
  • [18:19:25] <dpc> So if I'd write an OS in 30kB I could boot it directly?
  • [18:19:45] <dpc> How do I know how to store it on SD card? :)
  • [18:20:18] <av500> Ceriand|work: it can load more than 30k, if you use conf headers to setup sdram

  • [21:38:11] <jacekowski> anybody have experience with real time stuff on ARM?
  • [21:38:21] <jacekowski> but i need hard realtime
  • [21:38:51] <jacekowski> so i will have to disable caches and stuff ( performance is not so critical ) as i just need little bit more than typical 8 bit processor can give me
  • [21:43:50] <aholler> that doesn't make sense
  • [21:45:17] <ds2> jacekowski: disabling the cache is a huge hit... like going from 30seconds to boot to 10mins
  • [21:45:43] <aholler> if you don't more speed than some dozens mhz, than you could spend the few cycles a 800nhz-processor will spent in some not so realtime-stuff
  • [21:45:44] <mru> if you need it predictable you have no choice
  • [21:46:14] <ds2> a Cortex-R series mightbe more appropriate

  • [21:46:23] <mru> yes, probably
  • [21:46:27] <mru> they're made for such things
  • [21:46:32] <jacekowski> performance isn't a problem
  • [21:46:34] <ds2> :D
  • [21:46:36] <jacekowski> predictability is a problem
  • [21:46:50] <ds2> isn't the A8 also doing branch predictions?
  • [21:46:59] <mru> yes
  • [21:47:01] <jacekowski> it is
  • [21:47:03] <mru> can be disabled though
  • [21:47:07] <ds2> ah
  • [21:47:23] <jacekowski> i need to run something that in worst and best case scenario will execute in exactly same time
  • [21:47:43] <ds2> obviously don't want DFS either :D
  • [21:48:00] <aholler> exactly is relative
  • [21:48:15] <ds2> not for HRT
  • [21:48:29] <mru> there are still things you don't control precisely enough
  • [21:48:33] <jacekowski> well, i'll have to account for delays
  • [21:48:33] <mru> like dram refresh and whatnot
  • [21:48:38] <ds2> unless you like motors launching themselves at you or magic puffs of smoke coming out
  • [21:49:17] <mru> HRT is about knowing the worst case and designing for that
  • [21:49:17] <Ceriand|work> if your timing is really that critical, you should probably be using FPGA/CPLDs instead of software
  • [21:49:25] <mru> if it usually runs faster, that's not a problem
  • [21:49:36] <ds2> assuming you try to synchronize
  • [21:49:41] <mru> Ceriand|work: or a trained monkey
  • [21:49:57] <aholler> how do you define exactly? ms, ns, us, ...?
  • [21:50:46] <jacekowski> 10^-8s
  • [21:51:42] <ds2> DRAM issues can be worked around...i.e TCM
  • [21:51:56] <mru> only if you have some
  • [21:52:09] <mru> the a8 on omap3 doesn't
  • [21:52:11] <ds2> yes, that helps. more useful then 0byte programs
  • [21:52:22] <ds2> Cortex-R
  • [21:52:27] <mru> does a zero-byte program halt?
  • [21:52:40] <aholler> jacekowski: that was a rethoric question. I won't do the math for you ;)
  • [21:55:32] <ds2> and is that halting deterministic ;)
  • [21:55:58] <ds2> actually on the OMAP, is the internal SRAM deterministic like TCM?
  • [21:56:22] <Ceriand|work> you still have the L1/L2 caches on the A8
  • [21:56:25] <mru> you have to deal with L3
  • [21:56:33] <ds2> even for the SRAM?
  • [21:56:34] <mru> Ceriand|work: L1 and L2 can be disabled
  • [21:56:52] <mru> a8 has no other sram than L1/L2
  • [21:57:07] <mru> and even when disabled they add latency
  • [21:57:08] <ds2> no the A8 but the OMAP3
  • [21:57:18] <mru> there's 64k sram on L3

  • [21:57:38] <Ceriand|work> other bus masters on the L3 could skew timing probably
  • [21:58:22] <Ceriand|work> so you'd probably have to disable DMA
  • [21:58:44] <mru> the IVA L1 and L2 are accessible through L3 too though
  • [21:58:51] <mru> so you _could_ get interference there
  • [21:58:56] <aholler> jacekowski: just count how many processor cycles you could waste to still get a resolution of 10^-8
  • [21:59:10] <mru> the most predictable memory on tha omap3 is probably the tcm of the 968 behind the dsp

  • [23:47:03] <destinal> so, I'm getting started with embedded linux by hacking on some omap34xx and omap36xx based phones. I know the Cx is omap3530, but the new Mx line uses DaVinci DM37x -- is it 100% backwards comaptible, ie if I have a kernel that boots on 3530 will it run unmodified on the new davinci based beagle (not considering other devices outside the CPU)? just trying to figure out if I need to buy a...

  • [23:48:55] <cwillu_at_work> destinal, be aware that hardware differences can be significant hurdles even given the same processor
  • [23:49:52] <aholler> btw. could someone enlight me for what HRT stands for? ;)
  • [23:50:14] <destinal> cwillu_at_work: yeah, mainly wondering whether omap35xx will be any closer in binary compatibility than davinci, I realize the rest of the board is a hurdle no matter what :)

  • [23:51:13] <cwillu_at_work> The code in the kernel should be correct for that processor, yes. i.e., just a simple matter of having the right config options, and possibly the right patches :p
  • [23:52:31] <Max_Galemin> destinal: code for ARM Cortex-A8 is exactly the same on both processors :)

  • [23:53:37] <destinal> Do they use the same ti sgx ddk for the powervr? mainly I'm getting started learning how to use it (and it's far from trivial...)
  • [23:54:37] <destinal> I'm hoping that what I learn playing with beagleboard can directly apply to porting things to theses existing mobile handset devices
  • [23:55:27] <destinal> (sorry if I should be rtfm'ing something instead, I'm not really sure where to start)
  • [23:56:39] <aholler> thats why erveryone likes standards . you could waste more time than learning opengl. ;)
