I&#39;m assuming it setts the APPROTECT enable. My colleague Vidar explains in great detail in <a href="https://devzone.nordicsemi.com/f/nordic-q-a/92226/nrf52833-custom-board-halts-when-jlink-is-connected">this ticket </a>how to make sure APPROTECT is disabled on your board.</p> <p>To get it in an unprotected state in the first place, start by doing an nrfjprog --recover to recover the device into an &quot;open state&quot;.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
