I tested yesterday on a davinci board, I can confirm this behavior, I have not thought was an error. I do not see any code in fw_env.c to sort variables. I konow the variables are sorted in u-boot, but do we ever have this feature on the userland fw_printenv ? > 4. Since all seems well at this point, I reboot.

No CRC error, the environment was restored correctly after a reset and/or power cycle. > I added debug printf's to readenv() in env_nand.c and the root cause is > an error return from ret=nand_read(&nand_info[0], offset, &len, > char_ptr)).

At least this should not be a general failure, because it works on my target. It could be also nand specific.
