What is available on the nRF52840 for persistent storage (survives reboot / power cycle)?

I understand only the flash memory that stores the boot image is available.  We need ca 32 Kb of persistent storage.  How can that flash memory also be used for additional persistent storage?Is there software code to demonstrate read and writing to this persistent storage?

Hi,

You can use the Flash Storage library to read, write, and erase data in persistent flash storage. If you want to see how this library can be used, you can take a look at the Flash Storage example.

Best regards,

Thanks.  I'll take a look and let you know if I have anything to follow up on.
