When I run the same file against both utilities, they do not produce the same CRC.

The CRC of fw_setenv matches what uboot has when the environment is created inside the image.

fw_setenv is Linux userland to write to flash on the running system, right? And mkenvimage produces an image file IIRC.

Is this a known issue? If so, I am sorry to bring it up (but maybe remove mkenvimage...)

By chance: are your settings for redundant image the same? For fw_setenv this is set in file /etc/fw_env.config on the target system. For mkenvimage you pass -r as parameter or not.
