I took the u-boot from a linux sd-card image, it supports emac: U-Boot 2013.07-07795-g645e901-dirty (Aug 18 2013 - 16:15:54) Allwinner Technology CPU: Allwinner A20 (SUN7I) Board: Cubieboard2 I2C: ready DRAM: 1 GiB MMC: SUNXI SD/MMC: 0 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: emac Hit any key to stop autoboot: 0 It will set the mac address as soon as I do network stuff from within u-boot, not if only booting the bsd.umg. So looks like it works within the limited options we have right now. Kind regards Markus
