Is it possible to use the SWS connection with EVK + Swire for debug text output?

I see swire_putc() in the SDK and commands like tcdb uart l -s 4

Can these work together to allow debug print statements to work via SWS?

If so, are there any examples or documentation on how to make this work?

Many thanks.

hi wecango,
With swire_putc you will need a extra PC tool to pick up the text log, and the PC tool is not available for now. I would recommend you to use gpio simulate uart tx, which you could find an example in the 8258 SDK feature_test build file app_config.h, with UART_PRINT_DEBUG_ENABLE enabled you can output text log via gpio and use a serial tool to pick up the text log.
