Thanks for the detailed instructions Chill -which I tried now multiple
times- however I seem to miss an important point as the LCD remains
blank. Since my Pi Zero is still in delivery, I used a RPI4 with the
pirate-audio board instead. I do not know if the PI4 architecture causes
the problem or I missed something. If I follow the Mopidy installation
instructions, the screen functions as expected, but on PcP with your
instructions, I do not get any fb[0-1] devices or any response from the
LCD (audio part works)...
In the boot I do not see any evidence of the st7789v-spi.dtbo overlay
loading, despite it is in the config.txt. I do spot those errors, which
may be related in dmesg:
Code:

What am I missing?
