Hi,

Information is based on this post over on the SEGGER forums.

To use the RTT for OS X you need to launch/configure JLinkCommander(JLinkExe) with your connection settings, navigate to the folder containing the executable files and run JLinkExe -device nRF51422 -speed 4000 -if SWD, keep this window open, it is running the server that you are parsing RTT info from. In a different terminal you can now run JLinkRTTClient, and it will connect to your devkit.

Best regards,

Øyvind

If you are using nRF52 you would use JLinkExe -device nRF52832 -speed 4000 -if SWD, remember to use the latest versions as nRF52 support might be limited.

Thanks a lot works perfect to me :)

Tested these features today, some minor changes were needed:

• Instead of -device nRF52832 put -device NRF52
• Manually type connect and press enter.

I put up a full RTT minimal example on github for the nRF52 dev kit which works on OSX: github.com/.../rtt_minimal
