Writing to Flash on specific address on 52811https://devzone.nordicsemi.com/f/nordic-q-a/56050/writing-to-flash-on-specific-address-on-52811Hi, I&#39;m trying to write data to flash as shown in example under nrf5_sdk/examples/peripheral/flash_fstorage, with identical steps. However every time I call the nrf_fstorage_write, example nrf_fstorage_write(&amp;fstorage, 0x1C000, &amp;m_data, sizeof(m_dataen-USTelligent Community 13Mon, 30 Dec 2019 12:45:36 GMTRE: Writing to Flash on specific address on 52811https://devzone.nordicsemi.com/thread/227067?ContentTypeID=1Mon, 30 Dec 2019 12:45:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc365f1d-4cc6-444d-9656-bb700c507290Simon<ul> <li>Did&nbsp;<span>nrf_fstorage_write() return any error or is it a hard fault?

Normally, the storage modules check for stuff like that and will refuse to write in the application flash area (IIRC - did not verify source code).</p> <p>Also, fstorage has 2 modi: With softdevice enabled and without. We don&#39;t know which one is active in your project.</p><div style="clear:both;"></div>
