Hi,

All switches etc ook correct on the board, but just to be sure and in case fo bad connection, can you make sure the nRF power source switch is at VDD, and that the switch in the upper right end is at posstition "DEFAULT"?

Also, can you test other methods of programming the device, like nrfutil device or nRF Connect Programmer? Does that work? If not, can you share the log?

I'm installed j-link v7.94i to debug the board, that's the version that required nrfConnect.

Hi,

It seems the deubber is not able to comunicate with the target nRF. Are you using the onlboard debugger to debug the nRF on the DK, or an external board? Can you share a photo of your setup (I wonder if there are any connections, and the state of the switched on the DK). (Here is another thread about a similar issue).
