Hi, I believe while erasing the nand I accidentally skipped a step
before exiting minicom and since I haven't been able to boot. I'm
guessing this board is bricked based on the results Im seeing. Also I
realize it says "error reading boot sector" but I've tried multiple
cards and they aren't working I think I may have installed the wrong x-

Reading boot sector
Error: reading boot sector
Loading u-boot.bin from nand
stuck here /\
naturally I checked the various documentation available and followed
the steps on this wiki
However I'm not able to boot from MMC, or from USB while holding the
'user' button on boot. Instead I receive this result in minicom
40W`C�H�U��� I have no idea what these symbols mean. I
dont think they copied properly into this text field.
Instead I tried following the instructions for UART recovery, which
has worked for me in the past. However this time I'm not able to
connect using ukermit to swap the u-boot via minicom

How can I swap the u-boot if ukermit can't even transmit? I repeat the
same commands over and over with the same result.
ANY help at all would be appreciated. Thank you for your valuable
if you see 40W, then the board is not bricked. If you hold the user
button and cannot boot from SD card, it's 99% that you card is not
created correctly. Download images and follow instruction from
and you'll get you board back into working state. I had the same problem.
You were correct on my mistaken assertion that the board was bricked.
So I followed the instructions to install angstrom however I managed
to get this "wrong image format" error. Any ideas on a solution?

Grant - try stopping the countdown and typing “mmc init” instead of “mmcinit”. If it says “mmc1 available” (or something similar), try “boot”. It sounds like your boot script must be ancient.

you need to reset your environment to default. Have you went through
all the steps on the page I've sent you ? Or search this forum on
reset default environment, answer from Koen comes every week or so.
Thanks for all your help guys! Successfully ran angstrom, just needed
to flash the nand again and write a different u-boot to it. Watched
Big Buck Bunny, everything works great!
If anyone else has the same problems see the Beagleboard validation
Learned from my mistakes, much appreciation for your help.
