IMXRT1175 : HAB API does not work with 2 different IMG certificate

KrutarthRaut — Tue, 16 May 2023 10:32:24 GMT

Hello,

I am trying to achieve extended secure boot in which we need to authenticate Sw with HAB API.

Verification Tree is like, Internal ROM to Bootloader and Bootloader to APP file.

In this scenario, I am using IMG1 certificate for Bootloader (from attached CSF section below Bootloader Sw file) and for IMG2 certificate for APP (from attached CSF section below APP Sw file). API "hab_authenticate_image" is used for authentication.

API always gives me issue if I used IMG2 certificate but works fine with IMG1 certificate. Looks like, for 2nd iteration, HAB is not at all considering CSF section. Which looks like bug in HAB API development. Please can you share information if we can overcome this issue.

regards
