Rev A2 Beagle XM showing only 256Meg

Here's an angstrom boot log for comparison (note the date / version info on uboot)

U-Boot 2010.03-dirty (Aug 20 2010 - 20:50:46)

*** Warning - bad CRC or NAND, using default environment

Probing for expansion boards, if none are connected you'll see a harmless I2C error.

I'm pretty sure this is the lack of support of "Numonix" memory in Ubuntu's X-load.. Off the top of my head i don't remember which launchpad bug report has it, but your x-load needs this commit:

http://gitorious.org/beagleboard-validation/x-load/commit/ead751e4a361ce19552ac94bbeba232f12849244

Regards,

Tom, would you mind re-testing with x-loader 1.4.4git20100713-1ubuntu1?

Note that this x-loader was prepared on Wed 01 but was actually built 3 days ago.

Loïc,

Sure I'll give that a try today.

Thanks!

So installing the new version, copied over the new MLO from /usr/lib/x-load-omap to /dev/mmcblk0p1

Note the new file size:

-rwxr-xr-x 1 root root 18360 Aug 31 19:54 MLO

and that's it for messages out of the kernel....

I wonder about the angstrom kernel command line, here it is again:
[ 0.000000] Kernel command line: console=tty0 console=ttyS2,115200n8 mem=80M@0x80000000 mem=384M@0x88000000 mpurate=1000 buddy=none camera=lbcm3m1 vram=16M omapfb.vram=0:8M,1:4M,2:4M omapfb.mode=dvi:1024x768MR-16@60 omapdss.def_disp=dvi root=/dev/ram0 rw ramdisk_size=131072 initrd=0x88000000,128M rootfstype=ext2

Note those mem= params ... I wonder if we have that.....

mem= paramters are for TI's closed dsplink...

Otherwise I haven't seen that error on my xM A's yet..

Just for testing, incase it's the kernel and we are missing something else, do these work anybetter.. (they are built from Angstromss git tree)

odd it's not picking it up from the microSD card or picking up the file transfer via minicom anyway... I'll futz with this more first thing in the morning.

FWIW, this happens to me too. Happy to test anything you like that might fix it, so long as you can explain in words of one syllable how to test it :-)

with sakoman's MLO from http://www.sakoman.com/feeds/omap3/glibc/images/beagleboard/201009091145/ this appears to address the issue.

However either make sure to grab u-boot from there as well or get it from http://hudson.dooz.org/job/u-boot-linaro-stable/BOARD=omap3_beagle/

I think this has been fixed in the dailies for a week or so now, should we close the bug?

Fixed in the dailies.
