Hi,
I'm trying to use the samples/subsys/modbus/rtu_server/ sample. We use the st3485eb as rs485 driver. The problem is that I don't receive any data.
I'm converting our product from the nordic propritary code to zephyr. The nordic code works perfectly on the setup so it is not a hardware problem. The problem is in the configuration of the uart1 rx and tx lines. The configuration is below. The rx is on gpio0 bit 4 and the tx is on gpio0 bit 5, but it seems that at run time other port or bit values are used. Can you help me with the configuration?
