Hi,

SWO is not necessary to get basic debug information over RTT. Just connect SWDIO and SWDCLK correctly, make sure that RTT has been enabled as backend for the log module in the project settings. Then open J-link RTT viewer and you should be able to read out the debug logs.

Hi there,

What's reason for using SWO? It's usually not required to get log output from the RTT, that would only require SWDCLK and SWDIO,

Add ENABLE_SWO define will init 0.18 pin to be swo pin
