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.
Solved! Go to Solution.

Confirming that this should work per page 16 of the HW Interfaces Guide: WICED Smart™ Hardware Interfaces
If I were to guess, I problem is most likely linked to the Alternate functions for both pins:
P24
Alternate functions:
• SPI_CLK for SPI_2
P25
Alternate functions:
• MISO for SPI_2
We will need to escalate this internally to resolve.
