If this is a custom board, then probe the power supply and debugger SWD pins to see if you have proper voltages. I recommend you use another nRF DK as debugger to test your custom board

Hi Susheel,
- SDK Tool chain v3.0.2
- i tried a blinky sample ...
- No i install the Ubuntu 24.04.02 new on my machine.
- I performed the recovery, even using a batch file and in Bootloader mode, but I still have the same issue. I'm not sure whether it's a hardware or firmware problem.

Batch File :
#! /bin/bash
while true; do
nrfjprog --recover -f nrf52
done

Hi,

Which SDK version are you using and which sample or application are you attempting to flash into it? Did you previous flash attempt got interrupted or anything similar to that? I would run nrfjprog --recover -f nrf52 on your command prompt until it succeeds. If that fails to then I would check the power supply to the debugger and your nrf board.
