Copying the fstorage stuff into my own project, I &#39;m trying to erase 1 page at 0x3e000 and write an array of 12bytes after erasingen-USTelligent Community 13Tue, 07 Jul 2020 19:45:23 GMThttps://devzone.nordicsemi.com/thread/258878?ContentTypeID=1Tue, 07 Jul 2020 19:45:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c246a09b-be98-475a-8bbb-fa8af7e9afa0J&#248;rgen Holmefjord<p>Hi,</p> <p>Have you made sure that address 0x3e000 does not overlap with the application code area? The softdevice occupies the area up to address&nbsp;0x26000, so the application does not need to be huge to reach 0x3e000. Which example is your application based on? Can you post the code/project?</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
