Hi

I see this suggestion wasn't added in my last reply, but you have a rather old J-Link version installed according to the programmer app, can you try downloading the latest version to see if that helps? Does the DK work as expected with the nRFConnect apps on your computer? It sounds strange that it should slow your computer that much, is your computer by chance very old? Can you also describe how the Dongle is behaving when plugged in, is it pulsing red or behaving differently somehow?

Best regards,

Simon

Hi Simon

My Computer is very new AMD Ryzen 9 3900X, I have just downloaded the latest version of JLINK V7.6 installed fine, started up Programmer and still the log shows JLink version: JLink_V6.88a.

V7.6 is in C:\Program Files\SEGGER\JLink but programmer seems to be looking elsewhere.

Kind Regards

Hi Simon

I have now updated the Jlink the problem was Segger's default directory is C:/Program Files, but nRF Connect for Desktops default directory is C:/Program Files(x86).

Unfortunately though the problem still exists.

Kind Regards

Okay, can you explain what exactly you mean by the computer slowing down when using the DK? And does the DK work as intended or not?

There was a similar error in older nRFConnect versions (v3.8.0) with the same readFWinfo error, but we haven't seen this issue with the latest versions, but I guess you can try the workaround(s) described here: https://devzone.nordicsemi.com/f/nordic-q-a/81989/error-when-fetching-device-versions-readfwinfo-error/340278#340278

Best regards,

Hi Simon

Since the Jlink update the computer no longer slows down when using the nRF52840DK and also this Dev board works fine.

I will try the workaround and let you know

Kind Regards
