ESP32 Forum

Hi,

I would like to know if Secure Boot V2 can be used on a ESP32 rev ECO3 (WROOM/WROVER) while using IDF 3.3.5?

Thank you.

I'm afraid not, support was only added in ESP-IDF V4.1 so you will need V4.1 or newer. If updating ESP-IDF then suggest moving to the latest stable release version, V4.3.
