Interfacing (DSI, CSI, I2C, etc.) • Re: Configuring UART ttyAMA3 on CM4 module

Hi PhilE,
thank you very much for your support.
In the end it was the PI4J changing the pin muxing.
Is there a chance to prohibit pi4j doing this? Or shall i overwrite my pin definition file, so that it do not know these pins are also input pins and bind them strictly to RXD3, TDX3 & RXD4, TXD4? I saw soemthing with a .dts file were this can be changed. Is this correct?
