nRF5 SDK v15.0.0: FDS - Is alignment still required?

[awneil]

I saw this post for SDK v12.2:

The FDS requires data to be word-aligned 

devzone.nordicsemi.com/.../how-to-force-word-alignment-for-fds

Is that still true for v15 ?

I didn't see it mentioned in the documentation - am I just not looking hard enough?

Yes, FDS in SDK15 still requires data to be word-aligned.

[awneil]

and where is that stated in the documentation?

[FormerMember]

I cannot find it in the documentation, but if the data is not word-aligned, fds_record_write() -> write_enqueue() will return FDS_ERR_UNALIGNED_ADDR:

fds.c

if (!is_word_aligned(p_record->data.p_data))
    {
        return FDS_ERR_UNALIGNED_ADDR;
    }

Well, if you can't find it, and I can't find it - then I think that's a pretty clear indication that it's not properly documented?

A fundamental requirement like this needs to be clearly documented.

I agree, I will report it internally.
