Authenticate image on i.MX8 using AHAB

Hi,

I'm currently developing a secure boot solution for one of our customers using i.MX8DXL

1. I want to verify the image by signing the M4 image with CST.
Is it impossible with the sc_seco_authenticate() api, do I have to double check it with do_ahab_status() api?

2. That is, I wonder if it is necessary to check that there is no SECO Event by executing do_ahab_status to compose the verification code for m4 image.

Thank you
L.Duncan

Hi @minsiklee

I've checked with Local FAE Jessie Lee who has been working this case about AHAB issue.

Anyhow, also I've already informed the same that you have raised the issue. She would take care of your doubts.

Best regards

Harvey
