OpenHarmony-xiaomi poco f1

介绍

该项目介绍,如何在小米POCO F1上运行 OpenHarmony 4.0 Release标准系统。
支持图形显示硬件加速。
支持HDC连接。
支持WiFi

搭建开发环境

1.1 硬件环境

准备一台装有ubuntu20.04系统X86主机,内存最低配置要求16G。

1.2 下载repo脚本文件

  1. 注册码云gitee账号。

  2. 注册码云SSH公钥,请参考码云帮助中心

  3. 安装git客户端和git-lfs并配置用户信息。

git config --global user.name "yourname"
git config --global user.email "your-email-address"
git config --global credential.helper store
  1. 安装码云repo工具,可以执行如下命令。
curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo  
pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests

如果没有权限,可下载至其他目录,并将其配置到环境变量中chmod a+x /usr/local/bin/repo

mkdir ~/bin
curl https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 -o ~/bin/repo 
chmod a+x ~/bin/repo
pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests
vim ~/.bashrc               # 编辑环境变量
export PATH=~/bin:$PATH     # 在环境变量的最后添加一行repo路径信息
source ~/.bashrc            # 应用环境变量

1.3 获取OpenHarmony标准系统源码

通过repo + ssh 下载(需注册公钥,请参考码云帮助中心)。

export WORK_SPACE=/home/xxx/OpenHarmony #替换成自己定义的workspace路径
export PROJ_ROOT=$WORK_SPACE/4.0-Release
mkdir $WORK_SPACE
mkdir $PROJ_ROOT
cd $PROJ_ROOT
repo init -u https://gitee.com/openharmony/manifest -b OpenHarmony-4.0-Release --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'

1.4 获取编译工具链

参考OpenHamony快速入门文档,基于命令行入门。

sudo apt-get update && sudo apt-get install binutils git git-lfs gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4 bc gnutls-bin python3.8 python3-pip ruby default-jdk libssl-dev libtinfo5 genext2fs u-boot-tools mtools mtd-utils scons gcc-arm-none-eabi abootimg

1.5 执行prebuilts

在源码根目录下执行脚本,安装编译器及二进制工具。

cd $PROJ_ROOT
bash build/prebuilts_download.sh

小米设备代码下载与整合

2.1 下载适配源码

进到项目根目录,下载xiaomi dvice源码:

git clone -b OpenHarmony-4.0-Release https://gitee.com/ohos-porting-communities/vendor_xiaomi.git vendor/xiaomi
git clone -b OpenHarmony-4.0-Release https://gitee.com/ohos-porting-communities/device_board_xiaomi.git device/board/xiaomi
git clone -b OpenHarmony-4.0-Release https://gitee.com/ohos-porting-communities/device_soc_qualcomm.git device/soc/qualcomm

#下载米6内核(835内核)
git clone https://gitee.com/ohos-porting-communities/linux_sagit.git kernel/linux/linux-sagit
#下载845内核
git clone -b OpenHarmony-4.0-Release https://gitee.com/openharmony-dg/kernel_linux_6.3.git kernel/linux/linux-6.3

#因官方manifest在4.0分支去掉了eudev仓,需要手动下载eudev
git clone -b OpenHarmony-4.0-Release https://gitee.com/openharmony/third_party_eudev.git third_party/eudev

#手动合并以下补丁
#build
device/board/xiaomi/beryllium/patches/build.diff  

#foundation/graphic/graphic_2d仓  
device/board/xiaomi/beryllium/patches/graphic_2d.diff  

#drivers/peripheral/audio  
device/board/xiaomi/beryllium/patches/audio.diff  

#poco f1有两种机型,默认适配的是ebbg面板机型,tianma面板机型需要手动修改以下两个脚本文件
device/board/xiaomi/beryllium/kernel/make_kernel.mk
device/board/xiaomi/beryllium/kernel/make_bootimg.sh

#面板类型判断参考pmos的wiki
https://wiki.postmarketos.org/wiki/Xiaomi_POCO_F1_(xiaomi-beryllium)

代码编译

3.1 OpenHarmony编译

cd $PROJ_ROOT  

#小米POCO F1
./build.sh --product-name beryllium --ccache --no-prebuilt-sdk

#小米6
./build.sh --product-name sagit --ccache --no-prebuilt-sdk

编译成功提示:

post_process
=====build beryllium successful.

编译生成的文件

$PROJ_ROOT/out/beryllium/packages/phone/images/system.img 
$PROJ_ROOT/out/beryllium/packages/phone/images/vendor.img
$PROJ_ROOT/out/beryllium/packages/phone/images/userdata.img
$PROJ_ROOT/out/beryllium/packages/phone/images/ramdisk.img

3.2 boot.img编译

编译好OpenHarmony的文件之后使用以下命令内核并打包boot.img

#小米POCO F1
cd device/board/xiaomi/beryllium/kernel
./build_kernel.sh

镜像烧写

参考我的文章使用twrp刷入或者bootloader线刷
