Dear Steve Sakoman,

I patched readenv to use the same nand_read_skip_bad function used in the command line "nand read" tool. I no longer get the -EUCLEAN errors when reading the environment after using fw_setenv to write from linux. Now I get:
*** Warning - bad CRC, using default environment
Checking the data with the "nand read" command line shows that the changes I made in linux are indeed there, so I suspect that there is also some mismatch in the CRC computation between the fw tools and the u-boot code (i.e. I'm pretty sure this error does *not* refer to the nand CRC)
Try and use the "crc32" command in U-Boot tocheck if the checksum is correct. Check if the environment size in your board config file and in the fw_env.conf file match. Check if both match wether or not redundant env is used.
Best regards,
Wolfgang Denk
