I did a new try and get an other error, by reading 0x10000 starting at 0x43000000:

The best way to resolve this is to look into the Allwinner kernel sources from their BSP. It does have a script.bin parser, so we can improve sunxi-tools to support these newer script.bin variants.

Hmm ... where to get?
