Reconfiguration of default pin in UART peripheral?

[mushtakh]

I am following the example given in the  SDK v16 with nRF52832/ nRF52840. For the given example UART is working fine. But whenever I am changing the default pin configuration then UART is not working and gets to a system reset/ nrf_breakpoint_condition. I want to know which pins should I use except the default settings of RX and TX. I also want to know how to do it for the UART transmission. Please provide example code if any other than the example in the SDK..

The common problem is that the configured RX pin is not pulled high externally, this cause continuous reception errors. So try to pull the RX pin high.
