How to put FDS where i want ?

Hello,

I'm very new with nordic environment. i would like to modify the FDS address because it seems it is always put to the end of the flash and when i flash a new bootloader, it corrupts my FDS. As a result, my application cannot start because it identifies an issue with FDS.

How can i move the FDS. I was thinking is cas put at the end of the application, just before the bootloader.

best regards,

Aurélien
