OrangePi-Plus-2 boot process hangs in ubldr.bin

Hi all,

I've tried to upgrade u-boot on the OrangePi-Plus-2 (not the 2e) from 
mainline u-boot and on the outside it looks fine.

U-boot loads, and it boots ubldr.bin.

I'm using the orangepi-plus-2e.dtb as it has been working well for this 
board before (It all used to work).

Now ubldr can't boot the kernel though, and I don't know why. I've 
rebuilt ubldr, world and kernel from svn. Revision number is 317594

Any help would be appreciated

The output before it stops is:
