In this case, when you write once to the board, next write will not be possible without recovering the board. In other words, you need to disable readback protection by recovering the device. You can read more about readback protection <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf5340.html?highlight=readback#readback-protection-error">here</a>.<br /><br />Best regards,<br />Dejan</p><div style="clear:both;"></div>
