u-boot environment tool fw_setenv does not work when writing the environment to flash. Working with at91sam9260ek running kernel 2.6.20.
These are the traces:
# ./fw_setenv bootdelay 4 Warning: Bad CRC, using default environment Unlocking flash... Done Erasing old environment... Done Writing environment to /dev/mtd1... CRC write error on /dev/mtd1: Invalid argument Error: can't write fw_env to flash
Kernel printk: nand_write: Attempt to write not page aligned data
In /etc/fw_env.config configuration: $ more fw_env.config # Configuration file for fw_(printenv/saveenv) utility. # Up to two entries are valid, in this case the redundand # environment sector is assumed present.
# MTD device name Device offset Env. size Flash sector size /dev/mtd1 0x80000 0x20000 0x20000
Offset and environmet size as defined in myboard.h for u-boot compilation. I suppose flash sector size is the erase (block size).
Any help please?
