一、建立一个新的产品
1、创建如下路径
mkdir -p device/mycompany/myproduct
2、在myproduct下添加如下几个文件
- Android.mk
ifneq ($(filter myproduct, $(TARGET_DEVICE)),) LOCAL_PATH := $(call my-dir) # if some modules are built directly from this directory (not subdirectories),
# their rules should be written here. include $(call all-makefiles-under,$(LOCAL_PATH))
endif
LOCAL_PATH := $(call my-dir)
# if some modules are built directly from this directory (not subdirectories),
# their rules should be written here.
include $(call all-makefiles-under,$(LOCAL_PATH))
endif
- AndroidProducts.mk
#
# This file should set PRODUCT_MAKEFILES to a list of product makefiles
# to expose to the build system. LOCAL_DIR will already be set to
# the directory containing this file.
#
# This file may not rely on the value of any variable other than
# LOCAL_DIR; do not use any conditionals, and do not look up the
# value of any variable that isn't set in this file or in a file that
# it includes.
# PRODUCT_MAKEFILES := \
$(LOCAL_DIR)/myproduct.mk

二、集成Linux内核源码到Android代码中
1、将Linux内核代码拷贝到Android代码根目录下并重命名为kernel
2、添加AndroidKernel.mk到kernel中

3、在device/mycompany/myproduct/中添加配置文件AndroidBoard.mk
TARGET_KERNEL_CROSS_COMPILE_PREFIX := aarch64-linux-android-
TARGET_USES_UNCOMPRESSED_KERNEL := true
KERNEL_DEFCONFIG := defconfig
include kernel/AndroidKernel.mk
$(INSTALLED_KERNEL_TARGET): $(TARGET_PREBUILT_KERNEL) | $(ACP)

TARGET_USES_UNCOMPRESSED_KERNEL := true KERNEL_DEFCONFIG := defconfig include kernel/AndroidKernel.mk $(INSTALLED_KERNEL_TARGET): $(TARGET_PREBUILT_KERNEL) | $(ACP)
$(transform-prebuilt-to-target)
4、修改device/mycompany/myproduct/BoardConfig.mk
5、编译
lunch 24
make bootimage
. build/envsetup.sh
lunch 24
make bootimage
6、添加kernelclean目标

三、将U-Boot代码集成到Android编译系统中
1、将u-boot-2018.09拷贝到bootable下，并重命名为u-boot
2、在u-boot下添加AndroidU-boot.mk
ifeq ($(U-BOOT_TARGET),)
INSTALLED_U-BOOT_TARGET := $(PRODUCT_OUT)/u-boot.bin
endif
TARGET_U-BOOT_ARCH := $(strip $(TARGET_U-BOOT_ARCH))
TARGET_U-BOOT_CROSS_COMPILE_PREFIX := $(strip $(TARGET_U-BOOT_CROSS_COMPILE_PREFIX))
U-BOOT_DEFCONFIG := $(strip $(U-BOOT_DEFCONFIG))
U-BOOT_OUT := $(TARGET_OUT_INTERMEDIATES)/U-BOOT_OBJ
U-BOOT_CONFIG := $(U-BOOT_OUT)/.config
TARGET_PREBUILT_INT_U-BOOT := $(U-BOOT_OUT)/u-boot.bin
TARGET_PREBUILT_U-BOOT := $(TARGET_PREBUILT_INT_U-BOOT)
$(U-BOOT_OUT):
mkdir -p $(U-BOOT_OUT)
$(U-BOOT_CONFIG): $(U-BOOT_OUT)
$(MAKE) -C bootable/u-boot O=../../$(U-BOOT_OUT) ARCH=$(TARGET_U-BOOT_ARCH) CROSS_COMPILE=$(TARGET_U-BOOT_CROSS_COMPILE_PREFIX) $(U-BOOT_DEFCONFIG)
$(TARGET_PREBUILT_INT_U-BOOT): $(U-BOOT_OUT) $(U-BOOT_CONFIG)
$(hide) echo "Building u-boot..."
$(MAKE) -C bootable/u-boot O=../../$(U-BOOT_OUT) ARCH=$(TARGET_U-BOOT_ARCH) CROSS_COMPILE=$(TARGET_U-BOOT_CROSS_COMPILE_PREFIX)
U-BOOT_TARGET := $(strip $(INSTALLED_U-BOOT_TARGET))
ifeq ($(U-BOOT_TARGET),)
INSTALLED_U-BOOT_TARGET := $(PRODUCT_OUT)/u-boot.bin
endif TARGET_U-BOOT_ARCH := $(strip $(TARGET_U-BOOT_ARCH)) TARGET_U-BOOT_CROSS_COMPILE_PREFIX := $(strip $(TARGET_U-BOOT_CROSS_COMPILE_PREFIX)) U-BOOT_DEFCONFIG := $(strip $(U-BOOT_DEFCONFIG))
U-BOOT_OUT := $(TARGET_OUT_INTERMEDIATES)/U-BOOT_OBJ
U-BOOT_CONFIG := $(U-BOOT_OUT)/.config TARGET_PREBUILT_INT_U-BOOT := $(U-BOOT_OUT)/u-boot.bin TARGET_PREBUILT_U-BOOT := $(TARGET_PREBUILT_INT_U-BOOT) $(U-BOOT_OUT):
mkdir -p $(U-BOOT_OUT) $(U-BOOT_CONFIG): $(U-BOOT_OUT)
$(MAKE) -C bootable/u-boot O=../../$(U-BOOT_OUT) ARCH=$(TARGET_U-BOOT_ARCH) CROSS_COMPILE=$(TARGET_U-BOOT_CROSS_COMPILE_PREFIX) $(U-BOOT_DEFCONFIG) $(TARGET_PREBUILT_INT_U-BOOT): $(U-BOOT_OUT) $(U-BOOT_CONFIG)
$(hide) echo "Building u-boot..."
$(MAKE) -C bootable/u-boot O=../../$(U-BOOT_OUT) ARCH=$(TARGET_U-BOOT_ARCH) CROSS_COMPILE=$(TARGET_U-BOOT_CROSS_COMPILE_PREFIX)
3、修改device/mycompany/myproduct/AndroidBoard.mk
TARGET_U-BOOT_CROSS_COMPILE_PREFIX := aarch64-linux-android-
U-BOOT_DEFCONFIG := qemu_arm64_defconfig
include bootable/u-boot/AndroidU-boot.mk
$(INSTALLED_U-BOOT_TARGET): $(TARGET_PREBUILT_U-BOOT) | $(ACP)
$(transform-prebuilt-to-target)
TARGET_U-BOOT_ARCH := arm
TARGET_U-BOOT_CROSS_COMPILE_PREFIX := aarch64-linux-android-
U-BOOT_DEFCONFIG := qemu_arm64_defconfig include bootable/u-boot/AndroidU-boot.mk $(INSTALLED_U-BOOT_TARGET): $(TARGET_PREBUILT_U-BOOT) | $(ACP)
$(transform-prebuilt-to-target)
4、修改device/mycompany/myproduct/BoardConfig.mk
TARGET_NO_U-BOOT := false
5、修改build/core/Makefile
