  • [12:51:57] <sakoman> koen: thanks. I'm looking forward to doing some for beagleboard
  • [13:01:58] <koen> sakoman: the RTC looks like an easy one :)
  • [13:02:28] <sakoman> Yeah! NAND flash should be quite simple too
  • [13:02:37] <sakoman> And then frame buffer
  • [13:05:20] <Crofton> I'm using EXTRA_OECONF_append_arm in file to select some fixed point math routines

  • [16:39:27] <koen> there, RTC patch sent to linux-omap
  • [16:41:05] <jkridner|work> thanks.
  • [16:41:50] <jkridner|work> do you think there was something that could be done to the board to prevent this mishaps in the future?
  • [16:42:10] <jkridner|work> (the thanks was for the RTC patch, not busting your board. :) )
  • [16:43:45] <koen> jkridner|work: it really is a pebkac problem
  • [16:44:30] <koen> if you want to prevent it, you could use the really big and stout connectors that you mount through holes
  • [16:45:46] <koen> jkridner|work: one idea for when the beagle goes on sale: a small case for the beagle
  • [16:46:45] <koen> where 'case' might mean "8x8cm plexiglass with beagle mounted on studs"
  • [16:48:07] <jkridner|work> We are trying to keep Beagle as affordable as possible, despite the costs of manufacturing such fine pitch in such small quantities.
  • [16:48:23] <jkridner|work> after-market cases would be welcome.
  • [16:48:33] <koen> As you might have guessed, I have no idea about costs for things like that
  • [16:48:33] <jkridner|work> connectors probably aren't positioned the best for cases.
  • [16:49:55] <jkridner|work> This crowd is early adopters. Hopefully once a few hundred are out there, then demand for cases might be real enough. I'd be happy if a company who made money on hardware picked up the Beagle design and made it.
  • [16:50:02] <jkridner|work> I think we are just a bit early for that.
  • [16:50:22] <jkridner|work> your Angstrom distribution, however, is a nice lift.
  • [16:50:30] <ldesnogu> do you have an estimate of the number of units you will build?
  • [16:50:49] <jkridner|work> hmmm... I guess I can share.
  • [16:51:02] <jkridner|work> We are currently building 150.
  • [16:51:14] <jkridner|work> that should be the final run before "production".
  • [16:51:32] <jkridner|work> then, we will build another 800 or so.
  • [16:51:43] <jkridner|work> then it will be up to demand to drive building more.
  • [16:51:56] <jkridner|work> given the interest level, I believe they will all go quickly.
  • [16:52:10] <ldesnogu> indeed...
  • [16:53:02] <jkridner|work> if someone wants to make a big order, I suggest they start bugging me now (and show up with some $$).
  • [16:53:14] <jkridner|work> there are some big-lead-time items.
  • [16:53:36] <ldesnogu> the price is incredibly low compared to other boards, and given the power, there's no doubt the 800 will go in no time :)
  • [16:53:50] <jkridner|work> that has been part of the reason for such slow development. (It seems slow to me, anyway. I'm used to boards in 6 weeks. Not so easy with this fine pitch stuff.)
  • [16:55:55] <jkridner|work> at this point, I'm not comfortable pushing into my management's pockets for more. I'd be quite happy if someone else wanted to take a bit of a chance on this and we could share more financial details.
  • [16:56:10] <koen> I know people that bought a http://www.rabbit.com/products/RCM4300/ and were jealous about the beagle and the tincantools stuff
  • [16:57:20] <jkridner|work> That looks pretty neat, but definitely underpowered compared to Beagle.
  • [16:57:37] * jkridner|work pictures a beagle chasing a rabbit and feels silly.
  • [16:57:47] <ldesnogu> :)
  • [16:58:19] <koen> I'm glad the beagle isn't called ultrawolf 6000 or something like that
  • [17:00:41] <jkridner|work> :)
  • [17:06:21] <koen> wow, 2 reviews already
  • [17:06:27] <ali_as> sabretoothbeagle.
  • [17:06:43] <koen> one highlighting my inablity to make git do something usefull
  • [17:07:52] <jkridner|work> got a +1 from sakoman
  • [17:08:42] <koen> it's basically an s/evm/beagle/ on his rtc patch
  • [17:11:15] <jkridner|work> is the TWL4030 in the Kconfig already?
  • [17:11:30] <jkridner|work> I don't know that you'd want to have beagle in the #ifdef.
  • [17:12:16] <jkridner|work> oh, maybe I misunderstood his request.
  • [17:12:39] <koen> the ifdef as it is is in the 'wrong' place
  • [17:12:49] <koen> it will make sense once the lcd gets added :)
  • [17:13:05] <jkridner|work> where is the use of omap3_beagle_devices?
  • [17:13:22] <jkridner|work> ah.

  • [17:51:56] <zodttd> back... 2.6.22.1-omap1
  • [17:55:13] <koen> you could try git head or a prebuilt one from sakoman to see if things like CFS make a difference for your apps
  • [17:55:45] <koen> e.g. one from http://www.sakoman.net/omap3/
  • [17:56:11] <zodttd> Aha...Hmm I will definitely look into doing that.
  • [17:56:22] <zodttd> What is CFS though?
  • [17:56:34] <koen> completely fair scheduler
  • [17:56:39] <zodttd> aha!

  • [17:58:36] <sakoman> zodttd: Those images koen referred to are a few weeks old. I'm doing a clean build right now. I'll post fresh images when it completes
  • [17:58:36] <zodttd> I'd like to get my EVM as close as possible to what the Pandora will be. If it's going the OE route, I'd like OE, for instance.
  • [17:58:46] <zodttd> Awesome sakoman :)
  • [17:58:49] <zodttd> Thanks
  • [17:59:44] <zodttd> sakoman: Whats the main differences between whats built on the EVM, and your distro? I noticed you use a newer kernel.
  • [18:01:13] <sakoman> I'm mainly working on getting evm support into linux-omap, so the kernel is not as full featured as the one that ships with the evm
  • [18:01:45] <sakoman> But it is at the bleeding edge -- currently 2.6.26rc1
  • [18:02:07] <zodttd> Oh, I'm currently with a stock EVM.
  • [18:02:13] <zodttd> Very cool
  • [18:02:24] <sakoman> Has onenand, rtc, lcd, touchscreen, ethernet, usb, mmc
  • [18:02:42] <ldesnogu> So you have an OMAP3503 (and not 3530)?
  • [18:02:43] <sakoman> l2 not yet enabled, and no audio yet
  • [18:02:47] <sakoman> yes
  • [18:02:56] <sakoman> stock omap3 evm
  • [18:03:02] <zodttd> I have a 3530
  • [18:03:09] <ldesnogu> ha cool :)
  • [18:03:18] <sakoman> Should work just the same
  • [18:03:21] <zodttd> ok
  • [18:03:47] <sakoman> The rootfs image is an x11/gpe image
  • [18:04:03] <sakoman> Just an interesting collection of stuff to play & test with
  • [18:04:11] <zodttd> sakoman: By any chance would the process I've used (writing to the HW regs via /dev/mem) to overclock no longer work on your distro? ;)
  • [18:04:12] <koen> sakoman: the l2 patch in packages/linux/linux-omap2-git/beagleboard/ works like a charm
  • [18:04:44] <ldesnogu> zodttd: you should be careful about what sakoman wrote, L2 not enabled yet ;)
  • [18:04:55] <zodttd> aha
  • [18:04:55] <sakoman> koen: it's next on my list to add to the OE recipe, but obviously not for submission to linux-omap
  • [18:05:15] <sakoman> l2 should be enabled later today
  • [18:05:25] <zodttd> If L2 is disabled, I lose a large chunk of performance as koen noted
  • [18:05:29] <sakoman> I'll post that one too
  • [18:05:35] <zodttd> awesome
  • [18:05:39] <ldesnogu> indeed :)
  • [18:07:08] <sakoman> zodttd: no idea on /dev/mem What do you write? I could try it
  • [18:08:05] <zodttd> Heh, I first up the voltage of the vdd1 by writing a 5 to /sys/power/vdd1_opp_value
  • [18:08:29] <zodttd> Then I use some code I have...I can share if you'd like
  • [18:08:34] <sakoman> via command line?
  • [18:08:46] <zodttd> The voltage, yes. The /dev/mem, no
  • [18:10:13] <sakoman> Hmm . . . ls of /sys/power just has state
  • [18:10:27] <ldesnogu> how far did you push the frequency?
  • [18:10:28] <sakoman> so I may be missing stuff you need
  • [18:10:39] <zodttd> ldesnogu: ;)
  • [18:11:14] <zodttd> sakoman: Ah. I dont need to overclock though. Just would be an extra feature available.
  • [18:12:00] <zodttd> I only need to raise voltage to hit the 625MHz - 925MHz
  • [18:12:06] <sakoman> just trying to tackle the basics right now -- much easier to get those patches accepted :-)

  • [18:18:17] <Crofton> this sounds like endianess
  • [18:18:28] <koen> I would highly doubt that
  • [18:18:30] <Crofton> but, I must work on poster
  • [18:18:41] <Crofton> well, the data file came from a littel endian machine
  • [18:18:52] <koen> the omap is LE as well
  • [18:18:56] <zodttd> yeah
  • [18:19:01] <Crofton> er BE
  • [18:19:02] <Crofton> ppc
  • [18:19:10] <Crofton> but I should take of that
  • [18:19:15] <Crofton> code runs fine on intel
  • [18:19:37] <ldesnogu> so it's not an endianness issue :)
  • [18:20:27] <jkridner|wor1> koen: 'opkg install madplay' fails due to a lack of 'libid3tag0' is this right or do I have the wrong feed?

  • [18:22:20] <jkridner|work> I don't have armv7a base.
  • [18:22:28] <koen> but you do have armv6 base?

  • [18:24:11] <jkridner|work> I am.
  • [18:25:13] <koen> jkridner|work: I've seen this before, I'm 95% sure your proxy is caching the Packages.* file
  • [18:25:25] <koen> could you do 'md5sum /var/lib/opkg/*' ?
  • [18:25:45] <koen> the base one should be bba740d6934c0a135e110b919de92d08
  • [18:27:44] <jkridner|work> it is.
  • [18:27:58] <jkridner|work> I think it could be some other networking issue.
  • [18:28:07] <jkridner|work> I cannot wget it either, but I can from this machine.
  • [18:28:46] <koen> ah, so your proxy is sane :)
  • [18:29:00] <jkridner|work> yeah.
  • [18:29:26] <koen> it took us a while to track down that various ISPs perform caching
  • [18:29:35] <jkridner|work> koen: your 'from' address isn't in the beagleboard group list, so it got moderated. just sent it through.
  • [18:29:51] <koen> yes, my email setup is a mess
  • [18:30:13] <koen> I subscribed with my gmail address, which I only use to log into google stuff

  • [18:43:24] <jkridner|work> not having an IRQ handler would definitely be not-so-good.
  • [18:43:49] <koen> it shows that some of our stability problems aren't beagle specific
  • [18:47:01] <jkridner|work> Does it look like something is being missed in the patch?
  • [18:49:18] * koen has no idea
  • [18:49:58] <Crofton> we aren't really kernel hackers, we just pretend :)
  • [18:50:06] * koen isn't even a coder
  • [18:51:04] <Crofton> you could have fooled me
  • [18:51:05] <jkridner|work> :)
  • [18:58:04] <khilman> Crofton: can you share the kernel .config you used for your davinci angstrom stuff?
  • [18:58:12] <Crofton> well
  • [18:58:14] <Crofton> I would
  • [18:58:21] <Crofton> but I think I used the defconfig :)
  • [18:58:35] <khilman> I'm trying your rootfs with my own kernel, and I'm not getting to far into the userland
  • [18:58:41] <Crofton> I checked to make sure the SHM_FS was compiled in and used that
  • [18:58:48] <Crofton> what happens?
  • [18:59:00] <koen> Crofton: CONFIG_IKCONFIG=y
  • [18:59:00] <koen> CONFIG_IKCONFIG_PROC=y
  • [18:59:21] <koen> Crofton: and iirc the davinci kernel creates a /boot/config<something> as well
  • [18:59:29] <Crofton> hmmm, linux.inc may have manipulated it some
  • [18:59:58] <Crofton> let me see if the meta data browser is runnign
  • [19:00:28] <koen> I'm pretty syre it isn't running
  • [19:00:32] <Crofton> khilman, you tried the kernel I made?
  • [19:00:34] <khilman> I'm booting it over NFS, and udhcpcd starts and appears to whack eth0
  • [19:00:39] <Crofton> oh
  • [19:00:40] <Crofton> heh
  • [19:00:51] <Crofton> edit /etc/network/interfaces
  • [19:00:55] <koen> khilman: remove "auto eth0"
  • [19:01:04] <Crofton> find the line koen mentioned
  • [19:01:07] <koen> from the davinci rootfs
  • [19:01:07] <Crofton> and comment it out :)
  • [19:01:11] * khilman was just looking for that
  • [19:01:11] <Crofton> hahahahah
  • [19:01:23] <Crofton> can you tell we know all about that one
  • [19:01:35] <koen> stupid change of behaviour
  • [19:01:39] <koen> it used to Just Work
  • [19:01:51] <Crofton> where does that come from?
  • [19:02:18] <koen> no idea
  • [19:02:28] <koen> could be kernel, glibc, ifupdown, etc
  • [19:02:31] <Crofton> I suppose we should try to track that down
  • [19:02:47] <khilman> the other complaint during boot was:
  • [19:02:48] <koen> it started happening on my debian (x86) box a while ago as well
  • [19:02:49] <khilman> root: mount: mount point /proc/bus/usb does not exist
  • [19:03:16] <Crofton> usbfs?
  • [19:03:23] <koen> khilman: CONFIG_USB_DEVICEFS=y
  • [19:03:31] <Crofton> I better check that
  • [19:03:41] <Crofton> but, I need to clean my gutters before it rains
  • [19:04:03] <Crofton> khilman, I am leaving for Ireland for a week tomorrow
  • [19:04:09] <Crofton> so just a little stressed :)
  • [19:04:46] <khilman> koen: DEVICEFS=y is in my .config
  • [19:05:04] <khilman> but I have he usb stuff all built as modules
  • [19:05:50] <khilman> ok, with the 'auto eth0' removed, I've booted to a shell
  • [19:06:07] <Crofton> great
  • [19:07:06] <khilman> now, I just have to learn oe a bit better so I can build the stuff myself
  • [19:07:50] <Crofton> we should also talk about davinci stuff in #davinci :)
