Hi Rajesh,

Could you try to erase the DK and then try flashing the code again.?

Hi Rajesh,

I believe you have somehow enabled readback protection in the device.. Could you try running nrfjprog --recover.?

Hi Rajesh,

You need to open cmd and run the command nrfjprog --recover

As for using wireshark, you could take a look at this documentation: https://infocenter.nordicsemi.com/pdf/nRF_Sniffer_UG_v2.2.pdf

Also, which application are you trying to flash onto the board.?

Regards,

Swathy
