Did this with the image and specified cubieboard2.  On the serial 
console I see:

U-Boot SPL 2015.07-rc1-00513-g5bcec54 (Jun 17 2015 - 13:46:13)
DRAM:Timeout initialising DRAM

resetting ...

U-Boot SPL 2015.07-rc1-00513-g5bcec54 (Jun 17 2015 - 13:46:13)

and so forth.  :(  Now what?

Oh, and my F22 mSD card starts with:

U-Boot SPL 2015.01 (Feb 07 2015 - 22:08:32)
DRAM: 1024 MiB
CPU: 960000000Hz, AXI/AHB/APB: 3/2/2


U-Boot 2015.01 (Feb 07 2015 - 22:08:32) Allwinner Technology

CPU:   Allwinner A20 (SUN7I)
I2C:   ready
