FIP Secure Boot Can't Find Key

[bblouin]

I've followed this walkthrough perfectly: https://wiki.st.com/stm32mpu/wiki/How_to_perform_Secure_Boot_from_Distribution_package#Distribution_package_with_signed_FIP

and I get a "Not able to find "None" (socname stm32mp15) path from current BBPATH var: ..." when trying to have TF-A find the FIP signing key.

Please help

Hello

I think you might need to set this variable too

FIP_SIGN_KEY_stm32mp15 = "path to key"

Excellent...

The next question is, why isn't this in the "How to perform secure boot..." but that's for another day.
