Hello,
Image: bluewavestudio-openauto-pro-release-3.3.1
Hardware:
- Raspberry Pi 3b+
- Raspberry 7" touchscreen - connected with a ribbon cable to the DSI and two jumper cables (5v and GND)
- Hifiberry Amp2 (also used for powering the system)
Problem:
When I boot up the system, after attaching the Hifiberry Amp2 and adding "dtoverlay=hifiberry-dacplus" to the config.txt, the touchscreen goes nuts and it looks as if it is touched everywhere all the time.
What I tried:

What I tried:
- I detached the Amp2, uncommented "dtoverlay=hifiberry-dacplus" and everything was fine again.
- I only connected the necessary GPIO Pins of the Amp2 with jumper cable and reenabled "dtoverlay=hifiberry-dacplus", the issue was back.
- I kept "dtoverlay=hifiberry-dacplus" enabled and disconnected the Amp2, issue was still there.
- I flashed a micro sd with crankshaft-ng, attached the Amp2 and everything is working fine.
- I switched back to Openauto Pro and replaced the config.txt with the config of the crankshaft-image, issue still exists.
- I tried an apt dist-upgrade, issue still exists.
- I tried a rpi-upgrade (firmeware upgrade), issue still exists.
