I have some problems getting print through SWO to work and was wondering if anyone got it to work through either OpenSDA Jlink or with the external segger Jlink pro debugger?
When I try to use the JlinkSWOviewer with OpenSDA USB, it says "The connected emulator does not support serial wire output (SWO)"
With the Jlink pro, it does not complain, however I get no output.
Looking at the schematics it kinda seems like the SWO is not connected to the J21 JTAG tdo, only through the J34 connector.
Grateful if anyone who can shed some light?
