ong here. MX25 runs at 400 MHz maximum

hi,
i have recompiled u-boot with last stable release U-Boot 2010.09 and i have the same problem, i tried to move environment variables in a different memory block but the problem is still there. Is strange that uboot see badblock that redboot don't see...

U-Boot 2010.09 (Dec 17 2010 - 14:35:56)

After reset:

i don't understand why the first time is successfully and after reset don't work anymore.
