Pre-load data in FDS, cloning devices

[ColdBrew667]

Hi everyone,

I am currently working on a project that leads me to save a respectful amount of data. Some of the objects that I save size a few KB actually.

I would like to use FDS all the time to manage them even though I need to start with initial values and I would like those initial values not being part of the application to save a maximum of space.

Question is : is it a good idea to "clone" my file system from device to device?

What I envision is having one specific application that would create my whole file system in FDS, then dump the FDS pages into a hex file and then use this hex file as one of the other hex files I am loading onto my devices that have the normal application.

Do you see any issue with this solution?

Thank you for your help!

Well, I was wondering if this kind of trick can be also played during a DFU sequence. Say I have one device in the field, it has been initiated with the Hex file of the FDS portion. Now my application changed and I have new files to add to the existing file system. Let us say I agree to loose user data during DFU, will it be possible for me to flash the FDS section again on the field? Or am I again stuck with init values being part of the app and then create files in FDS using code?
