That's unexpected that image for rockpi4 boots on the rockpro64 board, but 
image for rockpro64 does not boot properly on the rockpro64 board...

The only diff between V1 and V2 seems to be the audio codec setup. So, I 
suspect this does not prevent the board to boot.

You can update the DTB file that u-boot loads, by interrupting the auto-boot 
and setting the DTB file in u-boot. (you likely need a serial for that).
