Setenv Errors

Hello,

I have recently started to build a new SD card and I had it all
working but upon completion I could not use make to compile some
drivers that I was using. I realized that I had not set my environment
variables so I went back to change that, but when I did it messed
something up and now I can not get past the boot. This is what ends up
being displayed for
me:

U-Boot 2011.03-rc1-00000-g5ace684-dirty (May 15 2011 - 18:50:56)

Err: serial
Beagle Rev Ax/Bx

These boards with that u-boot are broken..

It's fixed in u-boot head and 2011.06-rc's, with these 2 commits:

http://git.denx.de/?p=u-boot.git;a=commit;h=8feafcc49c0b7a9c541904f95a43dbef2fecc38b
http://git.denx.de/?p=u-boot.git;a=commit;h=4ca9244d74f146a0605f5bee28a66e39aae88d3e

The first patch doesn't apply cleanly to 2011.03...

MMC: block number 0x1 exceeds max(0x0)
** Can't read from device 0 **

** Unable to use mmc 0:1 for fatload **
Wrong Image Format for bootm command
ERROR: can't get kernel image!

Hello,

I have two different SD cards - one with the full Angstrom build on it (it was running the GUI and everything) and one that has a simplified version of Angstrom on it with only certain essentials running. Both of these SD cards were booting and running as desired until I changed the setenv variables. I have reinstalled the u-boot onto the one SD card (both individually and after running through the BeagleBootSetup completely).

I have also tried to use nand unlock but that command was unrecognized so I am not sure if I am in some sort of weird setting?

When I start the BeagleBoard I do get this at the top of the screen whether I start with either of the SD cards or without anything:

Minicom2.5 40V

I know that if you see 40T you have probably bricked the BeagleBoard, but I wasn’t sure if that was what that message was trying to say? (if that is the case I will follow the Beagle Board Recovery instructions again - I looked through them but I did not see anything that aligned with my problem.

Thank-you!
