File system for NOR flash

[Gurrug]

Could you advice any file system to include in our project for IoT application?
I hope that somebody on this forum had faced the similar problems.

We are looking for solution allows to make three function: write, read, erase. The system should works fast and be
insensitive to power failures.


Firstly, we tried to use Coffee file system https://github.com/contiki-os/contiki/wiki/Coffee-filesystem-example
But it works too slow.
Also we tried out to use the UBI FS / JAFFS systems from Linux. But actually we haven't enough RAM for this systems.

Therefore we are looking for something else.

The our prototype has NOR flash (64 Mb). Controller stm32f3*.

have you considered FAT filesystem (FAT32) . is there any difficulty in adopting it ?

How large is your Ram?
Jffs2 file system is just designed for Nor flash. 64Mb is enough for it.
you can use a simple one.
