The configuration file `/etc/fw_env.config` contains information about the device, the offset and the environment size.
Your u-boot version uses a file instead of a memory region to store the compiled environment. This file seems to be inaccessible to fw_printenv ("Bad CRC"). Is there another way to create/alter the compiled environment?
