Boot loader query

Pavankumar bu

I am new to the boot loading sequence and I have few queries, which are mentioned below.

In Multi boot chain sequence, how the following are done,

1 )Hash validation to validate the u-boot binary
2) Hash validation to validate the Linux kernel binary

What are the PPA services?
How does X-loader/u-boot invokes PPA to calculate the hash value of the u-boot binray/the Linux kernel binary.

What is PA API ? And how does PPA invokes PA API(SHA1MD5 function).

Please let me know as early as possible.

Regards

Pavan

    Pavan,

    The information for implementing multi boot chain sequence is TI proprietary and requires NDA license agreement with TI.

    Please contact your TI representative if you need more information about the NDA license agreement.
