beagleboard and latest from git

beagleboard and latest from git

[Robert Berger]

Hi,

I'm trying to get some poky version to boot on my beagle-xm and managed
with the distgcc tweak to compile it.

There seems to be something funny going on with u-boot. It looks like it
changes to baud rate or something like this, since I cannot see any
useful output:

Texas Instruments X-Loader 1.4.4ss (May 13 2011 - 08:39:41)
Beagle xM Rev A
Reading boot sector
Loading u-boot.bin from mmc
	\x04O�HJ$�z�mq��H�JI�ka
... more stuff coming ...

I followed the instructions for the instructions in README.hardware to
create boot.scr

So I just used some older known working u-boot.bin and the kernel comes
up until:

regulator_init_complete: incomplete constraints, leaving VDAC on
twl_rtc twl_rtc: setting system clock to 2000-01-01 00:00:00 UTC (946684800)

... here it stucks ...

What is the "last known good" sato-sdk for the beagleboard?

Hi,

I switched a bit around between various versions in the meantime and
that's what I figured out:

1) the latest u-boot (or some configuration of it) from git does not
seem to work for the beagleboard

2) if I use U-Boot 2011.03-00038-g8d4addc-dirty (May 13 2011 - 00:01:02)
which comes with bernard-5.0.1 things look much better.

U-Boot 2010.12-00038-g8d4addc-dirty (May 13 2011 - 08:44:08) is the
suspect. Why does the latest and greatest from git use an older u-boot
version than bernard 5.0.1?

I interrupt the u-boot autoboot and do the following:

OMAP3 beagleboard.org # sete console "ttyO2,115200n8"
OMAP3 beagleboard.org # mmc rescan ${mmcdev}
OMAP3 beagleboard.org # run loaduimage
reading uImage

2632316 bytes read
OMAP3 beagleboard.org # run mmcboot

and voila:

Yocto (Built by Poky 5.0) 1.0+snapshot-20110512 beagleboard ttyO2

beagleboard login: root
root@beagleboard:~#

This time even with networking.

This means that the latest and greatest rootfs seems OK.

Regards,

Robert

Thanks for the analysis Robert. There is a bug open for this:

http://bugzilla.yoctoproject.org/show_bug.cgi?id=1029

If you want to take a shot and preparing a fix, please do. Otherwise,
we'll get to it for the M1 milestone.

Thanks,

Darren
