Secure boot process for Tegra k1

Hi All,

We didn’t find any reference document to understand the secure boot process for Tegra k1 processor.
Can you please give us the document link to understand the secure boot mechanism for Tegra k1 ?

Thanks in Advance.

Tegra may have more to add, but generally secure boot is a topic of the ARMv7 Cortex A series CPU documentation. First go here (you may need to create a login to go beyond start pages):
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.subset.swdev.abi/index.html

Then in the upper left corner there is a “Products” button from which you can choose “Cortex-A Series”. Once there you can choose “Cortex-A15 Processor”. From there you will be able to find various documents for the CPU features and architecture.

Thanks for the link.

I don’t think for the secure boot mechanism we have to use ARMv7 Cortex A series document.
Secure boot mechanism is specific to NVIDIA processor not the generic for ARM Cortex A series.

Can you please give us NVIDIA specific link for the secure boot mechanism ?

Here is a URL which talks about boot flow. Part of this is the RCM protocol, which is likely at least close to what you are looking for. It mentions developer boards probably won’t have this enabled, so if you are working with a Jetson such software may not do what you want:
