Here is how to enable UART on BCM943362WCD4 and BCM943341WCD1 as terminal output.

 

On both platforms, BCM943362WCD4 and BCM943341WCD1, the UART4 Rx pin is routed to the SW2 but it can be setup to receive data on the UART4 if the switch is not utilized.

 

Both UART4 Rx and Tx pins are routed to the "Breakout Header" on the evaluation platforms.

 

BCM943362WCD4 Platform:

     UART4-Tx -> J7-9

     UART4-Rx -> J7-6

To change the terminal serial port from USART1 to UART4 update the below definition in .../platforms/BCM943362WCD4/platform.h

 

BCM943341WCD1 Platform:

     UART4-Tx -> J7-20

     UART4-Rx -> J7-8

To change the terminal serial port from USART6 to UART4 update the below definition in .../platforms/BCM943341WCD1/platform.h

 

Attached are the updated platform files to support UART4.
