Yes, something fishy is going on with the memory setup…
From a working NetBSD boot:

channel 0 training pass!
channel 1 training pass!
change freq to 800MHz 1,0
Channel 0: LPDDR4,800MHz
Bus Width=32 Col=10 Bank=8 Row=16 CS=1 Die Bus-Width=16 Size=2048MB
Channel 1: LPDDR4,800MHz
Bus Width=32 Col=10 Bank=8 Row=16 CS=1 Die Bus-Width=16 Size=2048MB
256B stride
ch 0 ddrconfig = 0x101, ddrsize = 0x40
ch 1 ddrconfig = 0x101, ddrsize = 0x40

Suggests that memory really is differently setup. Funny thing it works with their image that uses the ayufan u-boot and works, if I try their 2020.10 version it fails much the same as ours :)

I’ll try to dig in and see what gives, it does boot with my pinebookpro 2020.10 u-boot/kernel alas without network…
