Working / sample programs crashing on Custom Board?

[Faizan]

Hi, I have made my custom board using nrf51422 sample chips (Which came nrf 51422DK ), but my working / sample program which works on DK gets crashed on custom Board.

Blinking works fine, but uart and other soft device programs crashes.

Marking on my chip is: NRF51422 QFAC A1 1503AD

When there is a APP_UART_COMMUNICATION_ERROR, the error_communication field contain the value of the ERRORSRC register. Bit 2 and 3 are set, which indicate that a framing error occurred (bit 2) and a break condition (bit 3). I don't understand what causes it, though.
