Cross Compile of older Beaglebone kernel

I am attempting to cross compile BBB using vagrant with older debian images - my challenge is trying to get a quick build for 3.8.13.

I have managed to build using 3.8.13-bone68 using Trusty debian but this doesn’t work trying am33x_v3.8 commit (from bb-kernel) so tried using Xenial version but am getting error I don’t understand:

Cloning into '/home/vagrant/beaglebone/bb-kernel/ignore/linux-src'...

This git tree is only used as a “git reference”… you can clone linus’s tree locally somewhere else in your file system, then update the system.sh file to point where this tree exits…

Good point, thanks Robert
