Sorry I though the prerequisites were known I would have provided a better case description.

When I start nRF Connect for Desktop v3.9.3, then click on RSSI viewer the log window at the bottom reports in red:

Failed to get the Library versions: : JLINKARM_DKK_COULD_NOT_BE_OPENED (Origin Failed to get module versions"

Hi Dennis,

I test the Programmer app of nRF Connect Desktop after uninstalling Java runtime on a Mac Air(M1). I can program DK board without any issue. This means J-Link driver should work properly without Java runtime.

How did you start J-Link?

Which step did the first error appear in?

Best regards,

Charlie

Thanks for your response.

FIrsrt error is Failed to get the library versions: JLINKARM_DKK_COULD_NOT_BE_OPENED

I am on a Apple MacBookPro, M1 processor and it does not come with java installed.

When I started j-link it reports

The operation couldn't be completed. Unable to locate Java Runtime .

Please visit http://www.java.comfor information on installing Java

Hi Dennis,

I did not see any prerequisite for java on the Segger J-Link Product page.

I also test the Programmer app of nRF Connect Desktop after uninstalling Java runtime on my Windows PC, and I do not have problem programming firmware to the DK board.

Can you provide more information about the issue you have encountered? It might be caused by other reasons.

Best regards,

Charlie
