Set device configuration defaults at manufacture

[nrbrook]

I have a firmware which uses FDS to store configuration, and I want to set some defaults at manufacture. The data might be hundreds of bytes. I could write the data as a binary blob to flash using nrfjprog, and on first boot load this data into memory and write it back to flash using FDS, however I thought it might be simpler to write it directly to flash in the format FDS expects, I can see the format is documented here.

1. Is writing to flash in FDS format a good approach, or do you have any other suggestions?
2. I don't suppose there is a python or C library for formatting data in FDS format?
3. Can I just tag the first page as data (2 header bytes) and then write the records required in the format described in the link above?
   1. Do I need to tag another page as swap?

Hi Nick,

Writing to flash in FDS format sounds good. But I am afraid there are no libraries relating to this and the page you referred is a good start.

In order to store a large amount of data, you can just increase the FDS_VIRTUAL_PAGE_SIZE in the ''sdk_config.h''.
