Hi everyone,

so im working on imx8qm secure boot and my question is how to know the load adress of the next stage(ATF) used inside the firmware if its already prebuilt?

Hello,

What do you mean by prebuilt?
Please note that you may build your atf (bl31) and use it for your image.

Best regards/Saludos,
Aldo.

Hi, i mean when i use your bsp layer the atf is build automatically without getting modified depending on my use case.how do i verify and load the next stage(bl32 or bl33) if i m not passing some arguments to the build (like load adress) or is this done by the atf auto by reading the container header?

Hello,

Thank you for the clarification, so I believe that you are refering to yocto build, then yes, ATF source is downloaded and built.

Also, yes you are correct each image has its own data structure (header) with information on:
The location of the image
Size of the image
Destination address

Best regards/Saludos,
Aldo.
