Assigning UART0 Tx

This sub question is also buried in another thread but so I wanted to ask this as an explicit new question.

 

I have set the bsp user_config.h file for "ittya:" and as the BSP_DEFAULT_IO_CHANNEL but I need PTA14 ALT3 on the K40dx256 to use UART0 TX0. How do I go about doing that in mqx? I know how to do this outside of mqx using Device Init but I don't see how to select a specific pin within an specific ALT configuration within MQX.

 

Right now I have mqx running correctly and opening the file block for the UART and using a printf but nothing comes out on the pin. Hence my assumption that the internal configuration is not correct.

 

Can anyone point me in the right direction please? Thanks

 

Robert
