ESP32 Forum

I have a working application running on ESP32E 4MB, and I've been running v4.4.2. I've decided to port to the latest v4, v4.4.6.

The WiFi is no longer starting up, seems related to NVS config. Scanning release notes, didn't see anything obvious related. Any thoughts to this problem?

Came across this, fixed the problem.

Don't forget to initialize NVS using nvs_flash_init() before enabling WiFi.
Previously that was not strictly required, as WiFi driver would also call nvs_flash_init if the application didn't. It doesn't do that anymore, so application should take care of NVS initialization before WiFi or Bluetooth drivers are started.
