Hi,

For nRF5 SDK, the flash region used by FDS is at the end of the application data region. This is hard coded within the FDS library, and the area is automatically detected.

By default, the last page of Flash on the device is used for Master Boot Record (MBR) data, and the application data is placed directly before that. If there is a DFU bootloader on the device, then that bootloader is next to the MBR data page, and so the application data pages are further down (lower memory addresses) right before the bootloader.

If you experience issues with use of FDS, or have difficulties setting it up and getting it to work, then please explain what you see and I may be able to help you out.

Regards,
Terje
