Hi,

are the NVS access functions for writing and reading thread safe or do I have to use a mutex in my user code when accessing/committing the flash to prevent concurrent access?

Thank you!

Best,
Malte

NVS functions (C API) do locking internally, preventing concurrent access.

Can some one confirm it that it is thread safe. we found internal fatfs gets corrupted easily. does not sound thread safe.

Erm, ESP_Iggr just confirmed it is thread safe, one post above yours.

Sorry bothering again. Is it thread safe against same namespace.
