nrfjprog --ids can't find any devices on windows

[Arne M.]

Hello,

I just recently got a nRF52840 board and tried to flash a nrf connect firmware (I built it myself and the firmware itself does work correctly) onto it.
But I noticed that nrfjprog doesn't find any devices, even thouth nrfutil does and COM ports are listed in windows.

What's wiered is that I can find the device on Linux, just not on Windows.

I also installed the nRF Connect Desktop app to ensure I have necessary drivers installed.

Do you have any idea how to fix this?

In the end the solution was that I had the wrong Version of J-Link installed. Make sure you have (at the point of writing this) Version 784f installed.
