Dears,
Our custom board using nRF52833 cannot connect to Jlink after flashed a program.
I had the board connected with the Jlink via VCC, GND, SWDCLK, SWDIO and RESET pins.
I tried to run: nrfjprog --recover as the guide here
But it not working.
Is there a way that I can re-program the nRF52833?
Why did this problem happen?
Best regards.
Dears,
My custom board is not detected.
I have log on J-Flash V7.66a
