Secure Boot V2- not able to flash the built bootloader

[jettyjett]

Hi everyone, I'm trying to activate Secure Boot V2 on my ESP32-WROOM-32E revision 3. Following the documentation and I'm stuck at step 6, https://docs.espressif.com/projects/esp ... re-boot-v2
after executing

Code: Select all

idf.py bootloader

I get the following error:

Code: Select all

Executing action: bootloader
Running ninja in directory /workspace/esp/hello_world/build
Executing "ninja bootloader"...
[1/3] Performing build step for 'bootloader'
ninja: no work to do.

Bootloader build complete. To flash, run this command:
Traceback (most recent call last):

I'm using --> IDF version : ESP-IDF v4.3-dev-907-g6c17e3a64

I can't therefore flash my bootloader. To my understanding this seems to be a problem with the SDK. Is there a workaround for it?
