thanks for the hint, but there is only 512kb flash on this board (with 64k sectors). I don't think there is enough room for a second copy of the environment. and in some way, the mac address has to find its way into one of these environments. i think there are more boards like this, esp. since there is this mac randomization code within the mvgbe driver. -- Michael _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
