配置新的product
细节介绍
以下步骤描述了怎么样去为新的手机设备和其他运行android的设备配置makefile
1. 创建一个公司的目录device/vendor
mkdir vendor/<company_name>
2. 创建一个products目录
mkdir vendor/<company_name>/products/
3. 创建一个专门配置product的makefile,叫vendor/ <company_name>/products/<first_product_name>.mk。这个文件至少包括:
$(call inherit-product, $(SRC_TARGET_DIR)/product/generic.mk)
# # Overrides
PRODUCT_NAME := <first_product_name>
PRODUCT_DEVICE := <board_name>
4. 增加专门配置product的变量到上面的makefile中去(具体变量 见文章末)
5. 在product目录下创建AndroidProducts.mk,这个mk文件指明自己的product make文件:
# # 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)/first_product_name.mk \
6. 在公司目录下创建一个专门配置Board的目录 他将包括一个makefile文件,任何使用这个板的product都可访问这个makefile
mkdir vendor/<company_name>/<board_name>
7. 在上面创建的目录下,创建BoardConfig.mk文件
# These definitions override the defaults in config/config.make for <board_name>
# # TARGET_NO_BOOTLOADER := false # TARGET_HARDWARE_3D := false
# TARGET_USE_GENERIC_AUDIO := true
8. 如果你希望修改系统的属性,就在<board_name>目录下创建system.prop文件
# system.prop for
# This overrides settings in the products/generic/system.prop file
# # rild.libpath=/system/lib/libreference-ril.so
# rild.libargs=-d /dev/ttyS0
9. 在AndroidProducts.mk中增加<second_product_name>.mk的指针
PRODUCT_MAKEFILES := \ $(LOCAL_DIR)/first_product_name.mk\ $(LOCAL_DIR)/second_product_name.mk
10. 在vendor/<company_name>/<board_name>目录下,必须包含一个Android.mk文件,这个mk文件至少包含以下内容:
# make file for new hardware from #
LOCAL_PATH := $(call my-dir)
ifeq ($(TARGET_PREBUILT_KERNEL),)
TARGET_PREBUILT_KERNEL := $(LOCAL_PATH)/kernel
endif
file := $(INSTALLED_KERNEL_TARGET)
ALL_PREBUILT += $(file)
$(file): $(TARGET_PREBUILT_KERNEL) | $(ACP)
$(transform-prebuilt-to-target)
LOCAL_PATH := vendor/<company_name>/<board_name>
include $(CLEAR_VARS)
11. 为同一个board创建第二个product,创建第二个product-specific makefile 文件,叫做<second_product_name>.mk。这个文件包含:
$(call inherit-product, $(SRC_TARGET_DIR)/product/generic.mk) # # Overrides PRODUCT_NAME := <second_product_name> PRODUCT_DEVICE := <board_name>
到现在为止,你应该有两个新的product了,叫做<first_product_name>和<second_product_name>,为了确认这个product正确配置,执行一下语句:
. build/envsetup.sh
make PRODUCT-<first_product_name>-user
你应该在/out/target/product/<board_name>下找到新的二进制文件
