syncing LittleFS to flash

[myklemykle]

Hi,

I may be mistaken, but in my situation it looks like LittleFS writes aren't sync'd to Flash until LIttleFS.end() is called. Is that right?

Is there a preferred method to force a sync, other than restarting LittleFS withLittleFS.end();LittleFS.begin(); ?

Thanks!

There's no page cache like on a real OS, so all you need to do is myfile.flush() or close and re-open the file to guarantee it's on flash. No need to stop/start the whole filesystem.
