Did not work. See below.

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
I found my notes from a year ago. I took the CubieTruck img and dd the Cubieboard2 uboot with:
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8; sync
Since both are A20 boards and the Cubieboard is an A10 board.
And this worked back with 1511 CubieTruck image and the Cubiebaord2 uboot I had.
But this does not work with the uboot you supplied. I tried your dd command and mine. What is:
conv=fsync, notrunc
?
Here is the screen output of the boot of the Cubieboard2 (btw, I have my CubieTruck up and running).
Note that the CubieTruck uboot is:

And the one below is 2011.9?
