Wear-leveling and Journaling file system for NOR flash?

May 30, 2018 3 Replies

What are folks using for reliable file system on for example SST26VF064B 64Mbit SQI flash? Naive FAT will quickly wear out device for some uses; needs a wear-leveling file system. Needs to be power-off safe as well; no corrupted file system from arbitrarily-timed power cut. Anybody? Thanks, Best Regards, Dave



PS: A customer of ours used TINY by HCC some years back. It is unfortunately neither very well performing nor stable; led to product recall because it didn't properly wear-level and flash devices failed...

might be a good start to select another flash file system.

The cool kids seem to be using spiffs, for smaller systems anyway.
