  • [11:26:04] <Crofton> good, we need people like that :)
  • [11:27:29] <DJWillis> For now, 32bit X84 building for ARMv6/v7 - Built a few noddy helper scripts, worked out some personal conventions and now I have OMAP3EVM and a good chunk of Pandora going, of course the next step is to get a better kernel sorted for Pandora and build the whole lot clean, that will be fun (not) ;-)

  • [13:30:58] <koen|uni> there, now I officially know what eye-diagrams are
  • [13:31:45] <Crofton> awesome
  • [14:00:56] <ali_as> That's a good article on the atom.
  • [14:01:20] <NishanthMenon> Folks, one question: are we ok to see U-Boot V2 patches as RFC on beagleboard mailing list prior to me sending it to mainline u-Boot list?
  • [14:02:48] <Crofton> sure
  • [14:03:06] <Crofton> do we know if u-boot v2 will ever be widely used?
  • [14:03:29] <sakoman> NishanthMenon: sounds good to me too since I don't subscribe to the u-boot list. too many lists, not enough time.
  • [14:04:00] <sakoman> Crofton: we can help make it widely used :-)
  • [14:04:02] <NishanthMenon> Crofton, well.. it is a new thingy.. shrug.. as of date, well... most folks(including me) find u-boot v2 to be nascent.. lots of work to do to get a good feature in
  • [14:04:26] <Crofton> I haven't looked at it
  • [14:05:06] <NishanthMenon> but i personally feel that it is better architected (since it copies linux kernel arch) and has better chance of getting stable. further any newbie who has at least a limited knowledge of kernel will find right at home in u-boot v2!
  • [14:05:40] <NishanthMenon> and ofcourse.. i love being able to use valgrind on sandbox and sparse on arm code...
  • [14:06:47] <NishanthMenon> will send the patches out in couple of hours..
  • [14:25:12] <jkridner_> I'll ask the dumb question: what are "valgrind on sandbox" and "sparse on arm"? Do you mean for memory leak detection?
  • [14:32:55] <NishanthMenon> jkridner_, yes.. u-boot v2 has a build option to build it for your desktop.. so you can write a new feature -> say additional hush commands.. and you'd like to check mem leaks.. yippieee.. valgrind comes to the rescue..
  • [14:33:43] <NishanthMenon> i was thinking of probably writing a dummy nand,nor and onenand device for sandbox to test fs support.. mebbe sometime in feature..
  • [14:33:50] <NishanthMenon> s/feature/future
  • [14:34:00] <jkridner_> k
  • [14:34:05] * jkridner_ is now known as jkridner
  • [14:34:50] <NishanthMenon> sparse on arm = make ARCH=arm C=1 CROSS_COMPILE=xyz or make ARCH=arm C=2 CROSS_COMPILE=xyz
  • [14:35:30] <jkridner> What does "C=x" mean?
  • [14:37:11] <NishanthMenon> it runs sparse. C=1 runs only on modified files, C=2 runs on all files (without compiling the files if they are already compiled).. sparse is a static analyser.. http://www.kernel.org/pub/software/devel/sparse/
  • [14:37:42] <NishanthMenon> same thing is present in kernel today too I believe..

  • [16:45:05] <koen> yeah
  • [16:45:10] <koen> itanic
  • [16:46:37] <koen> didn't the lack of proper compilers (and hence linux + windows support) kill itanium?
  • [16:47:25] <koen> or the excessie power use
  • [16:47:28] * koen can't remember

  • [17:20:40] <koen> sakoman: did you see the mcbsp patch on linux-omap?
  • [17:21:06] <sakoman> koen: yes
  • [17:21:24] <sakoman> I'm using it to replace my own similar patch
  • [17:21:52] <sakoman> Slowly making progress
  • [17:21:55] <koen> does mcbsp being a platform device mean I need to register it in my board file?
  • [17:22:26] <prpplague> koen: refresh my memory, the beagle have ntsc/pal output ?
  • [17:22:50] <koen> s-video, yes
  • [17:23:02] <koen> not yet supported in linux-omap git
  • [17:23:40] <prpplague> ahh
  • [17:23:45] <sakoman> You need to enable it in defconfig, I don't believe that you need to add anything to your existing board file
  • [17:24:01] <sakoman> You do need to add an SoC board file though
  • [17:24:42] <koen> for alsa, right?
  • [17:25:03] <sakoman> yes in alsa/soc
  • [17:25:16] <sakoman> that's where the connection to mcbsp happens
  • [17:25:28] <sakoman> still figuring this all out
  • [17:25:47] <koen> ok, I;m going to add the mcbsp-to-platformdev patches to linux-omap2_git.bb now
  • [17:25:59] <sakoman> this next patch set will not be as trivial as the previous ones :-)
  • [17:31:03] <sakoman> > 1000 lines already
  • [17:33:05] <koen> is it online somewhere?

  • [18:29:17] <dannyBlue> Hi Koen, i am picking up on OE amazing work kudos on that.
  • [18:30:04] <dannyBlue> it's a really great effort
  • [18:30:20] <dirk2> NishanthMenon: Ping
  • [18:33:09] <dannyBlue> So did last night discussion about ARM vs MIPS die size get any final conclusions?
  • [18:36:01] <prpplague> i think it boiled down to "it isn't the size of your processor, but how you use it"
  • [18:36:08] <dannyBlue> lol
  • [18:39:31] <dannyBlue> wel there are several conditionants in regards to size maybe mips is smaller but hotter... etc etc...
  • [18:39:55] <koen> for people interested in bootlogs: http://amethyst.openembedded.net/~koen/beagleboard/bootlog.2.6.23rc3.txt
  • [18:41:42] <dirk2> koen: .config ?
  • [18:42:38] <prpplague> koen: wheres apex booting?
  • [18:43:01] <dannyBlue> looks good i did not know that there was bluetooth support for the beagleboard
  • [18:43:27] <prpplague> koen: need to specify your LPJ value as part of the kernel args
  • [18:44:30] <koen> dirk2: http://amethyst.openembedded.net/~koen/beagleboard/defconfig.2.6.26rc3.txt
  • [18:44:58] <koen> prpplague: u-boot has a 3 seconds timeout atm, so specifying lpj is bogus in that regards
  • [18:44:59] <prpplague> koen: i assume right now you are just doing dev with a monolithic kernel
  • [18:45:09] <prpplague> koen: ahh
  • [18:45:27] <prpplague> koen: i'm freaky about boot time
  • [18:45:38] <koen> and lowlevel debug is on, so I get console messages twice
  • [18:45:56] <koen> disabling that and booting with 'quiet' would also make it faster
  • [18:46:09] <koen> and using rootwait instead of rootdelay
  • [18:46:10] <koen> etc :)
  • [18:46:20] <prpplague> yep
  • [18:46:43] <koen> dannyBlue: beagleboard has usb, so it has bluetooth support :)
  • [18:46:46] <prpplague> koen: i usually try for power on to usability in 10 seconds or less
  • [18:48:18] <dannyBlue> I have to go over the specs again... still don't have them memorized
  • [18:48:47] <koen> dannyBlue: it has an omap3530 + usb, that's all there is :)
  • [18:49:19] <dannyBlue> ah so the bluetooth is an optional module?
  • [18:49:29] <koen> usb dongle
  • [18:49:35] <koen> everything is optional :)
  • [18:50:15] <NishanthMenon> dirk2, pong. Sorry.. was tied up with meeting (yet again :( )

  • [19:13:19] <NishanthMenon> dirk2, you can use the uboot.bin I think by downloading over usb and using the result in minicom.. i still need to dig in to the perl script failure
  • [19:14:10] <NishanthMenon> dirk2, i think it has something to do with using usb to serial converter in linux.. probably the ioctl that Device-Serial pm is sending is not supported.. probably a c code might be better
