  • Debug Interface Hardware Requirements for Semihosting?

    I can find lots of stuff on the software side, but not too clear on the minimum debug interface hardware requirements for Semihosting.

    Specifically, is it sufficient to have just the 2-wire SWD interface - SWDIO and SWCLK - or is SWO also required;…

  • Keep Preprocessor Output AND Do Compile

    I can't see an option on the ARM compiler to keep the preprocessor output and do the compile.

    I can see:

    -P: Just do the preprocessing, without #line markers.

    But I can't see…
