Cboot source for NX Xavier


I would like to confirm latest source code for the NX. I did noticed two possible locations:

One is
Jetson Linux | NVIDIA Developer
When I compile it, the size is different from the default one extracted from the L4T Driver Package

There is also a version found at the following link:

But the one for the Xavier fails to compile.

Can you confirm that the first link the latest cboot code? Why is it a different size then the one in the L4T Driver Package
