https://devzone.nordicsemi.com/f/nordic-q-a/45456/nrf52832-flash-save-data-problemHi Engineer I am using nRF52832 to develop a product. I want to save a flag to flash (FDS) before leaving the factory, and then read this flag every time I turn it on, and enter the normal according to the flash save flag (0xAA).

The application code of the device is also written on the flash of the device, and is read as often as the flag you have stored.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/178809?ContentTypeID=1Thu, 28 Mar 2019 01:15:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:871d6105-6d6a-48c9-8d42-1b311cfa7877wangshuai<p>I am very worried that if the user reads the flag is not 0xAA in the future, then the product will stay in the calibration mode forever and it will not work properly. How can I deal with this potential problem?</p><div style="clear:both;"></div>
