[U-Boot-Users] saveenv
hi,
I am using MPC8272ADS based custom board. Flash is MBM29LV160T(FUJITSU). u-boot is u-boot-1.1.2
u-boot is working fine.But environment variables are not saved to the enviromental space.So it doesn't display saved environment variables after reset.
------------------------------------------------------------------ *** Warning - bad CRC, using default environment
In: serial Out: serial Err: serial -------------------------------------------------------------------
Note: For this flash unlock is not needed to erase readonly sectors of flash.Ithink it may be crc problem.
what may be the problem?please reply..
with regards, Nethra

You may want to update your code. 1.1.2 is very old.

And what exactly happens when you type "saveenv" ?
flash.Ithink it may be crc problem.
Indeed, that's what the message says. Well spotted.
