[U-Boot-Users] 8xx watchdog too short

[Antonio Di Bacco]

I mean that, when the environment is not good, the uboot write something into 
this sector and the right crc. it writes something like:

Saving Environment to Flash...
Un-Protected 1 sectors
Erasing Flash...
. done
Erased 1 sectors
Writing to Flash... done

Bye.
