Hi Robert, I'm not expecting any help/support from you on this, but here is some additional info you may find interesting. :-)
a) I haven't tried contacting Seeed about this. I did look around for a contact at Embest and I found a forum (http://www.embest-tech.cn/community/forum.php) and a way to file a support ticket (http://www.embest-tech.com/ticket/index.php). The forum is all Chinese. I spent some time looking at google-translated posts there hoping to find the magic fix, without luck. I suppose the next step will be to file a support ticket about it. b) The Embest BBB I received has the AM3359. I noticed that the element 14 website says their "Embest BBB" has the AM3358. This may not be relevant to my Ubuntu boot issue, but it seemed interesting. c) When I boot the Embest BBB and watch the console output, it ends like this: Hit any key to stop autoboot: 0 gpio: pin 53 (gpio 53) value is 1 mmc0 is current device micro SD card found mmc0 is current device gpio: pin 54 (gpio 54) value is 1 SD/MMC found on device 0 reading uEnv.txt 1204 bytes read in 3 ms (391.6 KiB/s) Loaded environment from uEnv.txt Importing environment from mmc ... Running uenvcmd ... reading zImage 3669712 bytes read in 420 ms (8.3 MiB/s) reading initrd.img 3005004 bytes read in 345 ms (8.3 MiB/s) reading /dtbs/am335x-boneblack.dtb 24884 bytes read in 9 ms (2.6 MiB/s) Wrong Ramdisk Image Format Ramdisk image is corrupt or invalid gpio: pin 55 (gpio 55) value is 1 ** File not found /boot/uImage ** But I can literally pop that same SD card out and put it in my BBB model A6 and it boots fine. I googled around for the error messages near the end, and got a few hits, but nothing that made sense to me as a workaround or explanation of why it fails on the Embest BBB. d) I did some poking around in U-Boot. The version says this: U-Boot 2013.04-rc1-14237-g90639fe-dirty (Apr 13 2013 - 13:57:11) arm-angstrom-linux-gnueabi-gcc (Linaro GCC 4.7-2013.02-01) 4.7.3 20130205 (prerelease) GNU ld (GNU Binutils) 2.22 Whereas the BBB A6 shows this for version: U-Boot 2013.04-dirty (Jul 10 2013 - 14:02:53) arm-angstrom-linux-gnueabi-gcc (Linaro GCC 4.7-2013.02-01) 4.7.3 20130205 (prerelease) GNU ld (GNU Binutils) 2.22 So there is a difference on the first line, but otherwise the versions are the same. Also, both boards return the same thing for 'mmcinfo'.
