Hi Baptiste,
that is actually something being planned (although with low prio). Some
of the older boards have this already implemented (look at the config
module for the msba2 and msb-430). For streamlining this all across
RIOT, I thing what we should to is to create a generic architecture like
this:
----------------------------------------------------
| light-weight persistent storage API |
----------------------------------------------------
| some kind of (static) multiplexing |
----------------------------------------------------
| low-level | low-level | low-level | I2C | . |
| SPI flash | EEPROM | on-chip | EEPROM | . |
| driver | driver | flash dri | driver | . |
----------------------------------------------------
Through the API on top it should subsequently then also be possible to
implement a real file system on top of this. In the end it think the
most important part is the separation of API and the actual drivers for
different storage 'devices'!
Again, this is just a rough draft, feel free to advance this discussion!
Cheers,
Hauke

Hi,
I know that Riot hasn't got a file system but I'm wondering if we
could still save some raw data in the ROM which would be available
after reset? Could we allow some space in the ROM and write some data?
By the way, have you planned to design a file system for Riot?
