That is exactly my concern as well. > >> I have seen _way_ more cases where data in EEPROM got lost than data >> loss from the environment. > > That's discouraging, do you have any advice for where to store the MAC > outside of nand, and not in an EEPROM? I cannot second that, we have always stored environment and vital product data in EEPROM (AT24C64). But VPD (includes MAC adresses) is never writen by u-boot; only read and made into respective setenv() variables. Check boards/emk/common/vpd.c for an idea.
