Hello,

Could you try to connect the DK to PC with different USB cable?

Hi Kazi Afroza Sultana , thanks for responding. I tried the recover param but unfortunately, it can't detect the debugger.

❯ nrfjprog --recover --log
ERROR: No debuggers were discovered.

Hello,

You may try to do recovering the SoC using nrfjprog --recover from the command line?

You may try to toggle the power switches or nRf only switch on and off couple of times to make sure they are connected properly?

Thanks.
