Check in code - fw_printenv / fw_setenv are supposed to work with a MTD device, and the MMC is not. There are some additional checks and handling of NOR and NAND devices is done differently. But there is no code for MMC. However, managing MMC is easier: no need of erasing flash, simply write into the device computing the CRC. You could add the required functions to rwad / write a buffer from MMC to fw_printenv (and posting here the patch, thanks !).
