The driver should be fixed.
The driver doesn't get probed again if mac-address is changed using "setenv ethaddr", so it has no chance to program anything. For program i understand, in this case with zynq, overtaking mac-address into his registers. There is per default no ROM to store some mac. > > Regards, > Bin cheers, Hannes _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
