Failure while FitImage signing [ openstlinux , stm32mp135f-dk ]

[Kbirane]

Hi!

I am trying to have full secure booting on the stm32mp platform, using FIP and fitImage on a custom distribution built using Yocto with the meta-st-stm32mp layer.

For the fit image signing, all steps are well described here [st wiki ] :

https://wiki.st.com/stm32mpu/wiki/How_to_create_Signed_FIT_image_from_Distribution_package

i haved added those modifications directly on stm32mp13-disco.conf (just for testing)

But i have this warning :

WARNING: u-boot-stm32mp-v2021.10-stm32mp-r2-r0 do_deploy: Failure while adding public key to u-boot binary. Verified boot won't be available.

So my kernel is well loaded but the signature is not checked.

I have changed nothing else after doing my repo sync (openstlinux/ yocto [ kirkstone]).

Is something there to add on configurations in order to implement FitImage signing ?

thanks.
