Hi,

I have ensured the problem with our hardware engineer. The camera’s i2c interface is connected to the display’s i2c interface, which will exist issues. So what I need to do is try to change the official dtb file and make the touchscreen driver probe from i2c1 interface.

At present, the quickest way is to use our usb touch screen. It is compatible with the official screen, but only USES a USB port.

Was this ever resolved? I’m running into the same issue.

I’m using the PI4b, Waveshare 4.3 DSI, and the B0245 OBISP. If I disable the touch it works fine, however I need the touch functionality for the app/hardware i’m developing.
