    Why P24(Txd) and P25(Rxd) does not work as puart pads?

      We want to use P24 and P25 pins as puart port but it is not working. Any suggestion?

       

      With BCM920737TAG board, I was able to use P33 and P32 pins as puart. On another custom build pcb I was able to use P2 and P0 pins as puart.

       

      Below is the function call I used configure puart pins

       

      puart_selectUartPads((uint8_t)33, (uint8_t)32, 0x00, 0x00);  -- working

       

      puart_selectUartPads((uint8_t)2, (uint8_t)0, 0x00, 0x00); -- working

       

      puart_selectUartPads((uint8_t)25, (uint8_t)24, 0x00, 0x00); -- not working -- I did monitored output of P24(Txd) and stays at low instead of high level.

       

      Please let me know any specific settings I need to do to use P24,P25 pins as puart port.
