Many thanks for testing. I pushed the patch I proposed.

Sure that could be nice and in that case we could revert the 9MiB offset
change in gnu/system/image/pinebook-pro.scm.

I also found that janneke used some kernel-arguments that could maybe
help you in this blog post:

Closing this one,

Thanks,

Hi,

u-boot for pretty much every rockchip system supported installs to an offset of
8MB, which is currently in the middle of generated disk images' root
filesystems. This patchset adds another disk-image option for devices that
require a larger root offset, and configures the pinebook-pro image to use it.

I chose a 9MB offset by adding the previous root offset of 1MB to the
additional 8MB offset required. I know at least u-boot-rockpro64-rk3399 doesn't
build to over 1MB in size, so it should be fine? Feel free to change the
specific offset used.

Thanks!
