I looked into it a bit more, this is actually an error in the documentation. The SoftDevice doesn't have to be enabled before you init FDS. It is however recommended to have it enabled, this is because this is how Fstorage have been most thoroughly tested. Hope that clears things up. I have reported this internally, to make the FDS documentation clearer that is.

Thanks for your answer. I'm indeed using the softdevice API as backend, but the Fstorage documentation says this about the softdevice API backend => " Can be used anytime the SoftDevice is present, regardless of its status (enabled/disabled)." (here) So I'm wondering why do we have to enable the softdevice if we use fstorage with fds but not if we use fstorage directly.

It depends on what backend you want Fstorage to use. You can use NVMC peripheral or SoftDevice flash API as backend. See this.

FDS_BACKEND tells FDS which backend Fstorage should be using.

If SoftDevice flash API is to be used as backend, you must initialize the SoftDevice before initializing FDS.
