Did not work. See below. On 12/18/2016 09:17 PM, Mandar Joshi wrote: >> So we need a Cubieboard2 image! It has been many a month since I played >> with uboot.

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: U-Boot 2016.09.01 (Oct 26 2016 - 13:24:48 +0000) Allwinner Technology And the one below is 2011.9? HELLO!
