Is it possible to access a shared filesystem between the M4 and M7 on STM32Mp1?

Hi @msche.1​ ,

Could you please further detail your need ?

On which device would be the filesystem located ?

As a general comment, recommended approach on MP1 is rather to benefit from Linux to access the filesystem and transfer data to M4 thanks to OpenAMP.

I'm looking for a way to have share non-volatile storage between cortex-A and cortex-M. I guess I can store it on cortex-A and push it over Virtual UART to cortex-M on startup, but it would seem better to just have both cores have access to non-volatile storage, not sure if this is available.
