Using Flash Data Storage library with nrf52840+external memory (connected through the QSPI) as backend

Hello,

If you want to use the FDS library with qspi you need to write a new backend for the FDS.

There already is a softdevice backend and a non-softdevice backend. You can see how they are implemented if you compare the examples:

SDK\examples\peripheral\flash_fds\pca10056\s140

vs

SDK\examples\peripheral\flash_fds\pca10056\blank

The discussion in the thread that you linked to doesn't really conclude by using the FDS library at all, so that is probably also an option.

Best regards,

So, it seems that I almost successfully wrote own QSPI backend  for Fstorage library and rewrite sone functions in Flash Data Storage library. Now, all my code that I used for storing/removing records on internal flash works on external Flash.

Unfortunately there is a trable with Peer Manager, it can't successfully store data on the external flash... So, at least on current implementation bonding functionality doesn't work... 

Have you managed to solve this (Peer Manager to store data on external flash)?  Is there a way to set both internal and external flash to work with FDS at the same time?

Thanks in advance and regards
