Segger JLink EDU not detected in nRF Connect v3.9.0 / Programmer v2.0

peanutman

Hi,

I use a Segger JLink EDU (the big version, not the mini) to flash some custom boards. This used to work fine until I upgraded nRF Connect and got Programmer v2.0.

Now my jlink is not detected at all anymore. I found some similar posts here concerning v3.8.0, but I thought v3.9.0 was supposed to fix the detection issues?

The log does not hint at anything being wrong (no errors or warnings). My OS is MacOS 10.15.7. 

Thank you

    I have found the issue. My target board was not connected to the debugger properly.

    It seems that since Programmer v2.0, the debugger will not be listed if it is not (or incorrectly) connected to the target board. In the previous versions it would still be in the list, even if the debugger wasn't connected to a target.

    Hi,

    Great that you found the issue!

    We have had reports of issues with the device list in v3.8 and v3.9 of nRF Connect for Desktop. Having a JLink debugger connected to the computer without the debugger being connected to anything will cause this issue.

    Best regards,

    Marte
