We have a new PPC based board which includes some SRAM (actually
Everspin MRAM).
I can't work out the best way to mount this device or what filing system
to run on it, any advice ?
Thanks
TJ

If it's a "persistent" SRAM with a battery, try look at it:
http://pramfs.sourceforge.net

Is it memory mapped somewhere? If it is you can emulate an MTD using the
"slram" driver.
Then you can just use whatever you like on top - JFFS2 or something that
thinks it's going to be on flash or something, ext2 if you're nuts. But,
seriously, with slram you *can* go nuts.

Thanks Matt,
Yes it's memory mapped.
I will give it a spin.
Regards
Tom
