What is the tag if I run the “./source_sync.sh” on jetpack 3.0?

On jetpack 3.0 and TX1,when I run the “./source_sync.sh” ,it need a tag to sync.

You may try something like:

./source_sync.sh -k tegra-l4t-r28.2

You may adjust for your version.

Alternatively, you may find kernel sources in the source package, for example this one is for last JetPack.
