Hi, I am using nrf52832 with SDK 12.3.0 and nrf 52 dev board. I am experiencing a problem whenever  I programmed nrf 52832  using nrf52 dev board and NRFGO, after certain number of time ic 52832 do not get flashed and after replacing with new ic  it will work fine. what is the reason ?

Thanks in Advance

Hi

It might be that readback protection is enabled. Could you try the nrfjprog command recover, and see if it enables you to program it?

nrfjprog --recover
