File-system for NOR flash

[ranran]

Hello,

I am struggling with integration of filesystem on external nor.

I've been trying both littlefs, and spiffs. Both, with no success yet.

Is there any suggestion from ST for filesystem example on external nor flash ?

Thank you!

What exactly went wrong with littlefs integration? Porting it should be straightforward - just implement functions for read/write/erase/sync operations on flash blocks. I found an example:

Right,

I tried again with littlefs after seeing your answer, and surprisingly it looks to be functional now.

Thanks!
