Programmer can't read the SEGGER JLINK version.

Hi Sir,
I am developing with the nRF52840.

I installed nRFConnect 5.2.1 and the programmer (version 4.6.2), Following the programmer’s prompts, I installed SEGGER J-Link v8.18 and updated the nRF Command Line Tools to v10.24.2, and added the J-Link executable to the system path (environment variables), but the programmer still cannot detect the J-Link version.

Could you please help me resolve this issue? Thank you.

  • Hi,

    I see. nRF Connect for Desktop use nrfutil under the hood, so I wonder if you can run this from the command line and share the output?

    nrfutil device list --log-level trace

    Also, can you check if Computer\HKEY_CURRENT_USER\SOFTWARE\SEGGER\J-Link exists in the Windows registry (using regedit or similar)? This should have been configured by the J-Link installer.

    Edit: Can you also test with verbose logging enabled in the Programmer app and upload the log file here? (Also, if you can do with the latest version again instead of the old that would be good). Enable verbose logging like this:
