GPIO on Ayufan 0.9.14 Build

[Thisone]

I'm trying to use the GPIOs on the Ayufan Ubuntu Build (bionic-mate-rockpro64-0.9.14-1159-armhf), but can't seem to get it working.
Apperently the libgpiod uses /dev/Gpiochip0, which is not on this version.

Problem is, that i have to use a Desktop Image, which supports the Pine Touchdisplay, for the Rest of the Program, and i can't seem to get the other Versions (like focal-mate-rockpro64-0.10.12-1184-armhf) running. 

So is there a way to use the GPIO pins on the 0.9.14 Version?

Debian kernel 6.1.20-2 (and later) support the Pine Touchdisplay, so if you install Debian Bookworm, it should all work*?
I think you're needlessly limiting yourself by only looking at Ayufan's images ... which also seem (a bit) dated.

*) don't use guided partition with using the whole disk (option 2 iirc) as that would create an unbootable system (as 1st partition starts at 1MB, overwriting u-boot). This is a bug in d-i

So i just have to Flash the Debian image (https://d-i.debian.org/daily-images/arm6...399.img.gz) on the eMMC, without the partition (https://d-i.debian.org/daily-images/arm6...ion.img.gz) to get it working? (files are from the Getting started page).

I can't seem to get the debian Image working on the Rockpro. What Steps do I have to take, to get it working?
