2010-07-15 03:34:50     board briked after "saveenv"

On a board designed after the BF537 stamp, I manage to flash & boot u-boot from NOR, but each time I change my env variables  and I save them ("saveenv") the board isn't booting anymore.


The u-boot I use works perfectly on my BF537-STAMP eval board.


Any idea ?

using the fw_* utilities works fine, apparently the problem is only using u-boot saveenv

if you dont have the same flash layout as the stamp, then you cannot use the same settings or things like this will occur


verify your env sector settings match your flash in your board config


also, you seem to be simply modifying the bf537-stamp board code.  dont do that.  create your own board files.
