The SoC is the same, but the PineBook Pro and RockPro64 have different 
u-boot bootloaders: u-boot-rockpro64-rk3399-bootloader and 
u-boot-pinebook-pro-rk3399-bootloader, both in gnu/bootloader/u-boot.scm .

I have attached the image config that I used to build a RockPro64 image 
last week. See below for my plans to upstream.

FWIW, the PineBook Pro image is at gnu/system/images/pinebook-pro.scm

That should be useful, to be able to build aarch64 images without having 
to do cross-compilation.


However, it's inconvenient that each aarch64 platform needs its own 
aarch64 image. To improve on this, I'm working on Tow-Boot[0] support 
for Guix. The result is that a single generic aarch64 image will work 
across all Tow-Boot supported devices[1], including the RockPro64.
