So we need a Cubieboard2 image! It has been many a month since I played with uboot. Can someone point me to how to convert the Cubieboard1 image to a Cubieboard2?
I will work for a while with the CubieTruck.
This might work. I don't have a Cubieboard 2, so you'll have to experiment a bit yourself.
Get the U-boot for Cubieboard 2 (untested) from https://github.com/mndar/rbf/tree/master/files/cubieboard2
Wrie it to your micro sd using
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8 conv=fsync,notrunc
