On the Arria10, a signed SPL using the FUSE method does not boot at all, but it does boot when using the USER method. The behavior is the same as if we had not programmed the fuses. Details : Usi...

Hi @nareshrkumar,

Thanks you for your feedback.

I'm working with Christian and Baptiste. Without further information, the project, that we working on is currently at a deadlock situation.
Do you have new information about how to bypass the reset that can be triggered by quartus ?

- Have you encountered/known issues with certain Quartus version ? (standard, pro or specific version number)
- If the USB blaster forces the reset, is there a method to bypass it using Quartus?


Thanks,
Théo

Hi Theo, Christian and Baptiste

Thank you for the information shared.

As of today, I am not aware of any known issues with a Quartus version.

As the issue involves multiple components, U-Boot, Quartus, programmer and signing tool etc., I am working with different teams internally to get definitive information. Please give me some more time, I will update you on the status.

Thanks

Naresh

      Hi Theo, Christian and Baptiste

      Thank you for the wait.

      I have collected the information relevant to various use cases for Secure Boot in A10 but I need the below information to narrow it to your use case and help with the same.

      My questions:

      1. What is your objective with the Secure Boot in A10, is it for image authentication, encryption or both?

      2. Also, can you please share all the steps you have run for the "fuse" use case?

      Thanks

        Hi @nareshrkumar , @Jeet14

        Thank you for your help

        About your previous questions :

        1. What is your objective with the Secure Boot in A10, is it for image authentication, encryption or both?
        Our objective is to enable image authentification only.

        2. Also, can you please share all the steps you have run for the "fuse" use case?
        The steps followed for the "fuse" use case are identical to those for "user" mode (first post), except that when executing "alt_authtool.py", we use the "sign -t fuse" option instead of "sign -t user".

        If you have any further questions, please don't hesitate to ask.

        Thanks,

        Christian & Baptiste & Théo
