I am having trouble getting UART1 to work on an RZ/N1S. The pinmux is setup for UART0_I on both GPIO82 and GPIO102 with GPIO82 being my TX GPIO102 being my RX line. I am able to send messages out of UART1 TX (GPIO82) just fine. But the reply to GPIO201 doesn't appear to make it into RX FIFO and I never see bUart_DR go high. DR goes high and everything is fine in Loopback mode. I have even tried tying my TX directly to my RX externally to make sure that it has nothing to do with the message target (which is an MSP430 FRAM Controller). Messages on the RX and TX wires are both visible on the scope. I also switch GPIO82 to a GPIO output and GPIO102 to be GPIO input with the pins still tied together externally. If I toggled the GPIO82 state, I could see the corresponding change on GPIO102 in my firmware. Any thoughts as to what my RX problem could be? Please let me know if you need any additional information from me. Thanks
