Build Kernel

$ sudo apt install gcc-arm-linux-gnueabihf libssl-dev $ cd kernel/rpi $ ARCH=arm scripts/kconfig/merge_config.sh arch/arm/configs/bcm2709_defconfig kernel/configs/android-base.config kernel/configs/android-recommended.config $ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make zImage $ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make dtbs

Install python mako module

$ sudo apt install python-mako

Build Android source

Continue build with http://source.android.com/source/building.html $ source build/envsetup.sh $ lunch rpi3-eng $ make ramdisk systemimage vendorimage

Prepare sd card

Partitions of the card should be set-up like followings. p1 256MB for BOOT : Do fdisk : W95 FAT32(LBA) & Bootable, mkfs.vfat p2 640MB for /system : Do fdisk, new primary partition p3 128MB for /vendor : Do fdisk, new primary partition p4 remainings for /data : Do fdisk, mkfs.ext4 Set volume label for /data partition as userdata : use -L option of mkfs.ext4, e2label command, or -n option of mkfs.vfat

Write system & vendor partition

$ cd out/target/product/rpi3 $ sudo dd if=system.img of=/dev/ bs=1M $ sudo dd if=vendor.img of=/dev/ bs=1M

Copy kernel & ramdisk to BOOT partition

device/brcm/rpi3/boot/* to p1:/ kernel/rpi/arch/arm/boot/zImage to p1:/ kernel/rpi/arch/arm/boot/dts/bcm2710-rpi-3-b.dtb to p1:/ kernel/rpi/arch/arm/boot/dts/overlays/vc4-kms-v3d.dtbo to p1:/overlays/vc4-kms-v3d.dtbo out/target/product/rpi3/ramdisk.img to p1:/

HDMI_MODE : If DVI monitor does not work, try followings for p1:/config.txt

hdmi_group=2 hdmi_mode=85
