GPIO Monitor with touchscreen not working

[simoccc]

Hi,

I'm trying to make it working on my RPi 4B with a 4" touchscreen monitor connnected with GPIO.

I'm using your .img , I need to install monitor drivers after the first power up to see something in the display but after that I cannot see any Digiview background image on screen , only the prompt of the fpvout user.
Maybe something in the drivers broke Digiview ?

My display is a 4" and the drivers I installed are here:

git clone https://github.com/goodtft/LCD-show.git

and I used :

./MHS40-show

after that and one reboot the display started working but I got only a prompt and if I try to start even manually fpvout-start.sh it says:

fpvout@FPVOut:~ $ /home/fpvout/fpvout-start.sh
unable to open device, or device not found
try running as root (with sudo)

strace:
