I have modified snip.uart by changing all references to STDIO_UART to WICED_UART_2,
but no data is seen on the TX pin. Is there something else I need to configure to use this UART?
My platform is the ISM43362_MG3_L44.
No, nothing else is needed. I traced the problem to a pin numbering error on the
break-out board we built to plug into the ISM43362_MG3_L44 EVB expansion header.
