How to burn multiple secure boot key digests with Flash Download Tool

Postby benboppo » Thu Jun 19, 2025 9:24 am

Based on the recommendations in https://docs.espressif.com/projects/esp ... ot-v2.html I am signing my bootloader with 3 signing keys.

If my manufacturer wants to use Flash Download Tool (https://docs.espressif.com/projects/esp ... _tool.html) I can see an option for burning a single signing key digest efuse but I don't see options for the other two. Is there another way using Flash Download Tool or what is the recommendations for production flashing and burning of multiple secure boot keys?
