Hi TI

*SDK version: 9.11.00.18 ,example: key_node.

Because the pins we developed were not sufficient.,now  I want to use DIO 13  muxing  for the UART_TX  and control RF_Power。Now I want to control RF_Power independently as a GPIO.

Below is my setup.Is this configuration okay? Can the log be displayed normally?

    Hi Peisheng,

    I'm not fully understanding your question.  Are you trying to use DIO13 for both UART_TX and CONFIG_RF_0?  You will have to control the GPIO and UART TI Driver muxing in the application, not SysConfig.  The UART log will not be available while UART TX is being used for RF_0 instead.
