Hi, I think you should change your update_uboot script so that it only erases the sector with the bin. Are you updating u-boot from u-boot or from Linux (or some other OS)?
what if somethings goes wrong with the communication or power while copying u-boot.bin to flash?? i may loose important settings of my product in the field! u-boot.bin can always be updated using the BDI tool! But i cannot recover the environment variables.
In this case you would need to read the environment variables first and keep them backed up during the u-boot update.
