Segger and NRFGo are working fine.
I can see Segger in the device manager…

Any Idea what I made wrong… br Joachim

Hi @jwillner1958
Could you tell me which OS are you currently using?
Have you updated the drivers from the Nordic nRF52840 docs?
According to this forum reply, there is an incompatibility between openocd and JLink drivers, So try updating the J-link drivers and let me know the result.

I will Try the next days… Br Joachim

I have changed the driver with zadig. Now it is working fine…
