Due Serial Port Rx0 Tx0. Rx0 appears to fail

Question

Hi I can show the Tx0 port working fine with Atmel Studio,Jtag and the Uart Example program. The receiver Rx0 remains high/virtually nchanging when connected to an RS232 to 3.3V translator.

I have tried two boards with same result. Any guidance/experience with uart on Txo Rxo greatly appreciated.

Regards

Peter I will try a new path to cross check the electrical connection ( but the TX0 out does produce a signal generated from the Due code and it does appear on the output of the level shifter ). I will also review the example board_init() keeping Tx, Rx directionality in view. Happy to receive your 101 as I cannot id bug thus far! Stewart Lawton
