Tool/software: Linux
I can see the following log on power up, but I can't seem to get the console input to work. It simply does not register any input from my keyboard.
The debug console has remained unchanged from the AM5708 IDK (N24 for UART3 TX and N22 for UART3 RX).

I played around with mux_data.h file in my U-Boot source, while changes on TX work as expected, my changes on the RX seem to have no effect whatsoever:
{UART2_CTSN, (M1 | PIN_INPUT)}, /* uart2_ctsn.uart3_rxd */
{UART2_RTSN, (M1 | PIN_INPUT)}, /* uart2_rtsn.uart3_txd */
I also tried serial console flow control modes. No effect there. I also verified that electrically there isn't anything wrong (ie. I see activities on the trace).
Thoughts?
