Hello,

It shows from the error device is not connected to the debugger. Usually "cannot connect" error often indicates that the device is in a read-protected state or there is a communication issue with the J-Link debugger. How have you power your device? Ensure your USB cable is functional and that the power level of your target board matches the VDD of your programmer/debug probe. Can you show me the setup picture?

You can try this command to recover operation, which erases the entire flash and unlocks the device:

nrfjprog --recover -f NRF52
