On my mx53_loco board i have a problem:
when i add the command line help define (CONFIG_SYS_LONGHELP) in the board specific header, building complete successful but when i boot the board i find a corrupted environment (all commmands are unrecognized).
I have this problem even if i increase the size of the CONFIG_EXTRA_ENV_SETTINGS define.
So it seems to be a problem related to size of the u-boot code that overflows somewhere. (memory map re-definition?)
I would to be able to resize internal layout of u-boot correctly...
Can anyone explain me what happens or suggest a helpful link?
