mkdir ncar && cd ncar
repo init -u https://github.com/nkh-lab/aosp-ncar-manifest.git
repo sync -c -d

Or, if you want to use a specific release of AOSP (check supported releases in the branch list), specify it via the branch name:

repo init -u https://github.com/nkh-lab/aosp-ncar-manifest.git -b android-11.0.0_r48

Build:

. ./build/envsetup.sh
lunch ncar_x86-userdebug
make

Run:

emulator

Build:

. ./build/envsetup.sh
lunch ncar_hikey960-userdebug
make

If you're building for the first time, you'll be asked during lunch about downloading the Linaro binaries:

device/linaro/hikey/device-common.mk:36: warning: Missing Linaro Vendor Package!
device/linaro/hikey/device-common.mk:37: warning: Please download new binaries here:
device/linaro/hikey/device-common.mk:38: warning: https://releases.linaro.org/android/aosp-linaro-vendor-package/extract-linaro_devices-20220210.tgz
