I read the lengthy thread about unstable MAC addresses on the Cubietruck from September. However I'm still a bit confused about what I need to do to get a stable MAC address. Firstly my CT appears to have a non-zero SID: 01c23800: 16516501 80808955 54494848 0500f05c .eQ.U...HHIT\... I'm using the following uboot and kernel, both supplied by Fedora 21 as far as I know: U-Boot 2014.04 (Aug 19 2014 - 00:11:39) Allwinner Technology 1: Fedora (3.17.4-301.fc21.armv7hl+lpae) 21 (Twenty One) There are a few peculiar warnings at boot (see end of email), but otherwise it appears to work. However I don't get a stable MAC address. It seems completely random on each boot. Today I've had: 96:0c:ca:a9:c7:08 7e:68:c9:80:b8:01 ca:ea:b6:64:7b:5b Any ideas?
