So I got my rearview camera working with a catch.
As soon as I start the car and OAP boots, it goes straight to the rearview camera display, even when not in reverse.
If I close it and then go in reverse, nothing happens.
The only way to get it working again is to go into the settings of the rearview camera, set the GPIO back one or forward one (cam is set to GPIO25) and then go back to the GPIO that the cam is pinned to.
Then it works fine.
Am I missing something here?
I'm using the V4L2 method.
Specs:
RPi4 8GB
Waveshare 7.9" display 1280x400
Custom power supply that can go up to 15A if needed
UGreen Sound card
USB Video Grabber
USB TechKey Bluetooth Dongle
License plate rear view cam (brandless)
