@hongran86 How did you configure U-Boot on the MVME2500 to copy its environment to the MRAM?
IIRC there is no in-memory copy of the environment variable values while U-Boot is running, and U-Boot doesn't store them in the MRAM by default. I remember finding them in an i2c Flash EPROM when working with this board a few years back. If you added commands to move or copy them to the MRAM as part of the boot process that should be documented somewhere.
