STM32H573: OBKey Provisioning failed

[aco990]

Hello @Jocelyn RICARD , @D.Botelho 

I am trying to enable debug authentication on a stm32h573 mcu following this example: https://community.st.com/t5/stm32-mcus/how-to-enable-rdp-like-product-state-flash-protection-in-stm32h5/ta-p/708082.

I was able to generate the obk file and to transition the device to provisioning state:
This my xml file and the current product state:

 

But when trying to provision the obk file, i got this error:

Do you know what could be the problem and how to recover from this state and provision the device ?

Thank you!
