settings storage in external flash

[Bilal]

Hi,

Is it possible to use the Zephyr settings storage subsystem to store data in external flash?

We are dealing with some internal flash space issues and are trying to see if we can offload the "settings_storage" partition we currently have in internal flash to be stored in the external flash (using the MX25R32 flash device)

I tried updating our pm_static.yml file to define the parition like so:

settings_storage: { address: 0xf8000, device: MX25R32, region: external_flash }

But that throws errors when trying to save something to the settings subsystem.

Am I missing something? Is there something else I should be doing in order to be able to do this?

Is this even possible?

Any help would be appreciated, Thanks

Thanks Simon for the reply, but I don't think this answers my question.

We have already configured our external flash memory and have been using it to read and write data but I am specifically wondering if there is a way we can move the setting storage subsystem that Zephyr provides to be stored in the external flash rather than internal flash
