AGX Orin Kernel Customization Problem Jetpack 5.1.2

Hi,

Yes I have tried this before. but where is the original source_sync.sh located. because I have never found it on my System and do not know where it should be executed.

Also the Kernel Customization is not 100% clear about how to proceed if you compile directly on AGX Orin or on Host System. like in Step “To Build the Kernel” Bullet Point 5 where Linux_For_Tegra is referenced which is not available directly on AGX Orin.

Is there a more detailed Description of how to do that?

Sorry If I am missing something here but I am kind of helpless at the moment.
