i.MX 6UL: how to use HAB API

memrekaraaslan — Mon, 11 Nov 2019 11:20:11 GMT

Hello again Yuri

As you said, I read the documents https://www.nxp.com/docs/en/application-note/AN12263.pdf and High Assurance Boot Version 4 Application Programming Interface Reference Manual. I want to extend chain of trust and I guess, I should to use HAB API's. But I couldn't find any examples of them. For example, where should I use the Authenticate Image API function to validate the u-boot image? spl.c or hab.c or u-boot source code? I don't understand where to use the authentication APIs.

Thank you !

Hi Yuri,

I am also working on High Assurance Boot (for i.MX6ULL) and try to extend the chain of trust by authenicating addiditonal images, e.g. the kernel. For me it is also unclear how to use the HAB API. Do you have additional information and examples? Thanks!

best regards
