  • [10:01:07] <koen> I'm still unsure how hailstorm and dispc work together

  • [10:03:27] <zuh> Yeah, unless we can inject options through HAL (in similar fashion as you can specify a x11_driver field to force a custom driver)

  • [13:46:48] <Crofton|work> rscott_, you need to get the dsplink tarball from ti
  • [13:46:55] <Crofton|work> and put in your oe sources dir
  • [13:47:01] <Crofton|work> and create the md5sum file
  • [13:47:16] <Crofton|work> that said, I do not think the recipe is complete
  • [13:47:23] <rscott_> Ah! Thanks for that hint...
  • [13:47:50] <rscott_> I've also tried to use opkg, and it fetches the rc9 kernel, but not the associated modules...
  • [13:49:05] <rscott_> Also tried building the 1.51 dsplink module, but it appears to be out-of-date (the directory name is 2.6.18), and it fails to insmod.
  • [13:49:07] <Crofton|work> I think it is close, but not quite down
  • [13:49:19] <Crofton|work> we need to work with w TI guy on it

  • [13:52:00] <koen> I think it currently boils down to "sign an NDA to get the working bits for omap3"
  • [13:52:09] <Crofton|work> rscott_, most likey :)
  • [13:52:17] <koen> rscott_: the "2.6.18" is a TI way of saying "newer than 2.6.11"

  • [19:16:57] <sakoman> those are the rates that my 4030 codec driver supports

  • [19:30:50] <sakoman> These regressions are really annoying :-(
  • [19:31:28] <nathanm> The cable thing drives me nuts because it is very hard to access inside the machine I'm testing.
  • [19:31:51] <sakoman> nathanm: are you using a beagle board?
  • [19:32:00] <nathanm> Yes.
  • [19:32:42] <sakoman> The subtle differences between beagle and overo are driving me nuts! make no sense
  • [19:33:15] <sakoman> reboot and reset button work fine on Overo but not on Beagle. musb sort of works on Beagle but not at all on Overo
  • [19:34:00] <sakoman> Code from a couple of weeks back was much more consistent in behavior
  • [19:34:43] <nathanm> I agree. David says he is chasing timing bugs and that even the kernel configuration makes a difference in timing and thus bugginess.
  • [19:35:11] <nathanm> The patch that introduced the buggy plug/unplug behavior just moved files around in the tree, which changed some order of initialization and apparently timing.
  • [19:35:22] <sakoman> nathanm: yeah, David and I are trading lots of emails each day trying to sort this out
  • [19:36:07] <nathanm> I had things working very reliably before the big TWL4030 patch set. Most days I'm tempted to go back to that.
  • [19:36:34] <sakoman> nathanm: wish that was an option for me
  • [19:37:30] <sakoman> I need to get the wi2wi driver working so that means I need to be working at the head so my patches are easier to maintain

  • [19:40:40] <geist> still beta, right?
  • [19:40:49] <sakoman> geist: still beta, correct
  • [19:41:17] <sakoman> so far just the 100 Linux Summit attendees have them
  • [19:41:24] <geist> strange it doesn't work. since most of musb stuff goes through the twl4030, i'd expect that to be the same
  • [19:41:33] <geist> though there are lots of versions of that
  • [19:41:35] <sakoman> geist: indeed
  • [19:41:45] <geist> but thus far none of the version changes have bitten us in the butt
  • [19:41:57] <sakoman> Overo actually has parts labeled "5030"
  • [19:42:05] <geist> yeah, was gonna say, probably a 5030

  • [19:42:27] <sakoman> So TI says
  • [19:43:05] <sakoman> But then there are those inexplicable differences in behavior between beagle and overo
  • [19:43:13] <koen> the cynic in me says they are completely identical but have different partnumbers to keep the legal dept happy when opening up docs
  • [19:43:35] <geist> we didn't have to change any code as far as i know, and we're using most of the features of that chip
  • [19:43:39] <mru> koen: ;-)
  • [19:44:03] * mru has a large cynic inside
  • [19:44:11] <geist> sakoman: what about power rail differences between the boards?
  • [19:44:19] <geist> though for usb i dont think it matters that much
  • [19:44:52] <koen> mru: would it be worthwhile to add xv output to omapfblay, or would it be better to just use ffplay for that?
  • [19:44:53] <geist> and i assume the two boards are connected to the 4030 via the same ulpi interface?
  • [19:44:54] <sakoman> geist: shouldn't be a factor for musb, since it is self contained in the omap/5030 combo
  • [19:45:14] <geist> yeah, i wouldn't think so
  • [19:45:22] <sakoman> geist: interconnects are identical for the two
  • [19:45:26] <mru> koen: accessing fb directly is faster
  • [19:45:31] <sakoman> since there is only one way to connect them :-)
  • [19:46:00] <geist> yeah, i know the 4030 supports 3 wire usb and whatnot, but i think the omap3 is 8 wire ulpi only
  • [19:46:08] <sakoman> right
  • [19:46:41] <mru> koen: and I like the ability to play video without running X
  • [19:47:13] <geist> and i guess the pin muxing is set up properly, that might be in board specific code in le kernel

  • [19:47:44] <mru> there was a time when I had to stop X to free up enough cpu time and memory to play DVDs
  • [19:47:45] <geist> dunno, i remember the first time i got that musb driver working in our bootloader. it was a nightmare gettng the 4030 parameters correctly
  • [19:48:14] <geist> and then the musb part itself is a maze of errata and fail
  • [19:48:24] <koen> mru: memory is slightly less an issue now with my beagle :)
  • [19:48:45] <mru> buffering ~1000 frames in ram and ~30 on the graphics card did the trick back in the day
  • [19:48:59] <mru> had to write my own drivers of course
  • [19:49:16] <sakoman> geist: Dave and I have been using exactly the same bits on the boards
  • [19:49:25] <[X]Spot> Hi guys .. I am building Angstrom for beagleboard with OE following http://www.angstrom-distribution.org/building-%C3%A5ngstr%C3%B6m
  • [19:49:32] <[X]Spot> but when I start buinding bitbake base-image
  • [19:49:33] <sakoman> i.e. do a mmc boot using the same microSD card
  • [19:49:42] <[X]Spot> I receive the following error

  • [19:50:20] <geist> sakoman: but is the linux kernel got board specific bits for each one, or are you relying on them being wired up essentially the same way?
  • [19:50:39] <sakoman> the latter
  • [19:50:50] <[X]Spot> do you have any idea ?
  • [19:50:52] <geist> ah, well that makes it reasonably easy to figure out then
  • [19:51:11] <sakoman> geist: yes, one would think so :-)
  • [19:51:18] <geist> it's schematic diff time!
  • [19:51:32] <geist> if only you knew someone that knew how to read those...
  • [19:51:53] <sakoman> geist: I wish the Beagle schematic were easier to read
  • [19:51:57] <geist> can't be that much different from a hobbit
  • [19:52:05] <mru> schematics aren't what they used to be...
  • [19:52:13] <sakoman> the embedded pdf schematic pages are lousey quality
  • [19:52:21] <mru> nowadays it's just a few ICs and the odd capacitor
  • [19:54:09] <sakoman> sakoman: I sure the root cause is some subtle timing thing, because this wasn't an issue until the recent 4030 code revamp
  • [19:54:48] <mru> ethernet gadget got better for me after the changes
  • [19:55:03] <mru> it used to suffer random, brief disconnects
  • [19:55:19] <mru> and sometimes wouldn't be detected without re-plugging
  • [19:56:00] <sakoman> mru: I've seen that too
  • [19:57:13] <sakoman> geist: schematics aren't the painful part, it's doing hacks on a board crammed with 0201 discretes and bgas

  • [22:53:49] <Beagle7> so do you know which kit is good to start with for robotics
  • [22:54:07] <Beagle7> I dont see any sensors attached/built in with the beagle boardf
  • [22:54:36] <mru> no, but there's an expansion port
  • [22:55:07] <Beagle7> ok, any compatible one you know or recommend
  • [22:55:09] <nathanm> Most people are using USB boards such as Phidgets. The expansion port is not directly usable because it is 1.8V whereas most robot kits still use 3.3V or even 5V. I've heard of two efforts to make sensor/motor controllers that plug into the expansion port though.
  • [22:55:44] <ds2> using 1.8V is not difficult
  • [22:56:31] <nathanm> Yes, if you have some electronics training it's no biggie.
  • [22:56:50] <pbrook> ds2: Not difficult per se, but often does require additional electronics on top of what you'd normally need to a 3.3/5v board.
  • [22:56:56] <Crofton|work> Beagle7, ask prpplauge
  • [22:57:11] <Crofton|work> he is around during US business hours

  • [22:57:51] <nathanm> I also saw a robot on Saturday that was using a "Make Controller" (USB based) to interface to motors and sensors.
  • [22:58:10] <pbrook> IIRC prpplauge is already working on a general purpose IO board that gives you things like 5V lines.
