[U-Boot-Users] saveenv

[Nethra]

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" ?

Indeed, that's what the message says. Well spotted.
