Hi,

-If you are using the integrated debugger of the explorer board, pins (53:56) can be used for UART so if

      - 16-bit configuration is used, the lpp mode should be UART_ONLY

      - 32-bit configuration is used, the lpp mode should be DEFAULT

-If you want to use 16-bit configuration and DEFAULT lpp mode then pins (46:49) can be used for UART (this cannot use the integrated debugger)

Let me know which pins are you using for the UART and for which other firmware you are getting the debug prints.

Regards,

Hi,

I would like to add to my previous response that If you want to use integrated debugger of explorer board with  16-bit configuration and DEFAULT lpp mode then pins (46:49) should be shorted to pins (53:56).
