(8)Android之路====Android新增自定义项目配置

本次介绍并不是很深入,仅作为一种参考学习,在lunch的时候,打印出的每一条都是一个完整的项目,这里简单地介绍如何新增一个自定义的完整项目.

因为手头上有一个展锐的机子,所以,这里就以展锐平台为例进行介绍,其它平台配置也是类似的.主要分为4个部分:
PS: 手机SoC,展锐全球出货量占比27%,仅次于qcom, mtk,虽然不是技术第三,但销量目前稳稳的全球第三

1).Android层次项目配置
2).kernel层次项目配置
3).uboot层次项目配置
4).chipram层次项目配置

1).Android层次项目配置

配置一般是在device目录下面,我们这里也是把工程配置在这个下面,本次讲解比较浅显,主要以实现为目的.我手头上的机子是SC9832E,项目代号sharkle,我们这里基于官方提供的参考工程上进行修改来得到我们自己的工程.官方参考工程路径为: device\sprd\sharkle\, 我们参考下面的sp9832e_1h10工程,这里直接复制一份,然后在它的基础上进行修改:

# 进入工程目录
cd device/sprd/sharkle/

# 拷贝工程并重命令新工程为xshark_one_1h10
cp -avR sp9832e_1h10 xshark_one_1h10

# 进入xshark_one_1h10
cd xshark_one_1h10

# list
ls
AndroidBoard.mk     features  sp9832e_1h10_base.mk     system.prop
Android.mk          log_conf  sp9832e_1h10_native.mk   temp_img
AndroidProducts.mk  overlay   sp9832e_1h10_nosec.mk    vendorsetup.sh
BoardConfig.mk      recovery  sp9832e_1h10_oversea.mk
CleanSpec.mk        rootdir   sp9832e_1h10.xml

# 删除不必要的工程配置文件
rm sp9832e_1h10_nosec.mk sp9832e_1h10_oversea.mk

# 修改工程为我们项目名称
mv sp9832e_1h10_native.mk xshark_one_1h10_native.mk

# 修改自定义工程
vim xshark_one_1h10_native.mk

做完上述步骤之后,我们就已经打开了xshark_one_1h10_native.mk文件,我们做如下修改:

到这里,基本上已经配置完了,也就是,我么已经做了一个新的项目了,我们在Android的根目录: source ./build/envsetup.sh后,再lunch就可以看到我们新配置的工程出现了,之后,就可以通过选定和编译了.

2).kernel层次项目配置

本步配置主要是配置Linux内核,意在适配不同硬件,单独编译是:make bootimage -j32,主要生成:boot.img, dt.img, kernel, ramdisk.img

cd kernel4.4/sprd-board-config/sharkle/sp9832e_1h10/
cp sp9832e_1h10_native xshark_one_1h10_native

做如下配置:

接着做defconfig的配置,如下:

cd kernel4.4/arch/arm64/configs/
cp sprd_sharkle_defconfig xshark_one_defconfig

添加dts文件:

做如下修改:

3).uboot层次项目配置

本步骤主要是配置uboot,单独编译是:make bootloader -j32,主要生成:uboot.bin,也就是BL2阶段的代码.

3.1, 添加Kconfig支持

3.3, 添加头文件

cd u-boot15/include/configs
cp sp9832e_1h10.h xshark_one_1h10.h

3.4, 添加defconfig

cd u-boot15/configs
cp sp9832e_1h10_defconfig xshark_one_1h10_defconfig

 PRODUCT_DEVICE := sp9832e_1h10

配置好之后,uboot部分的简单配置就完成了,可以将编译后的uboot.bin刷机验证.

4).chipram层次项目配置

本步骤主要是配置chipram,单独编译是:make chipram -j32,主要生成:uboot-spl.bin,也就是BL1阶段的代码.

在根目录下的chipram/include/configs添加头文件,这里我们直接套用参考项目的:

mv sp9832e_1h10.h xshark_one_1h10.h

在chipram/board.def中添加配置,如下:

--- a/chipram/board.def   2019-06-10 15:53:35.225838044 +0800
