if you change manifest, then remove all except .repo to prevent building non-existent projects

repo forall -c git clean -fdx

I got the same problem today and I resolved it by deleting the cache folder(rm -rf ~/.ccache) and deleting the files *.o that were empty.
This problem may occur if your PC shutdown in the middle of a build.

repo.txt

As you may know - we've made Milestone 2 release based on Kernel 4.9
Some changes was made to our branches:

1) Nougat 

You will need to reinit repo:
repo init -u ssh://[email protected]:29418/renesas/platform/manifest -b r-car-7-K4.9

All branches for projects are r-car-7 except "common" projects(rcar-android-kernel-4.9) and  external/kernel-headers (r-car-7-K4.9)

2) Ncar
You will need to reinit repo:
repo init -u ssh://[email protected]:29418/renesas/platform/manifest -b r-ncar-4.9

All branches for projects are r-ncar except "common" projects(rcar-android-kernel-4.9) and  external/kernel-headers (r-ncar-4.9)


common projects for both androids are :
