Armbian 24.2 is broken on Orange PI PC2

[modbus]

I can confirm, that the problem is one dtb file /boot/dtb/allwinner/sun50i-h5-orangepi-pc2.dtb

 

Good working one:
In kernels 6.1.x (I checked kernels 6.1.77, 6.1.92) it has the size 35143 bytes.

 

Bad one:
In kernels 6.6.x or 6.7.x (I checked kernels 6.6.16, 6.6.31, 6.7.4, 6.7.12 ) it has the size 34856.

 

I downloaded latest community image: Armbian_community_24.8.0-trunk.205_Orangepipc2_bookworm_current_6.6.31_minimal.img.xz,
burned it to SD, and failed to boot, but then I replaced /boot/dtb/allwinner/sun50i-h5-orangepi-pc2.dtb from kernel 6.1.92, and it booted OK. Running Pi-hole + YCast without any problems.

 

Unless it is fixed, just remember if after "apt update" , if kernel is updated, it is necessary to replace /boot/dtb/allwinner/sun50i-h5-orangepi-pc2.dtb with the working one before rebooting system.

If you want to investigate further you could decompile the dtb and then compare the 2 dts files to see what changed. It shouldn't be too much I guess.

Please see this post (last post in the thread) and tell me if you need/want something from me...

After running the update from 6.1 > 6.6 it freezes at boot.

I have access to backup img:s from before this update is ran.

Well you could run dtdiff on those files and it should list all changes between those 2 versions. If it's only a single change that's it, if there are multiple ones it's a little trial and error to figure out which one caused it.
