1、环境准备
这个没啥好说的都是搞机的用之前编译 aosp 的 linux 环境就行有小伙伴担心会把之前的环境搞崩
也有用 docker 编译的我这里就直接在 aosp 环境下搞了还省事。
安装下面这三东西是为了下载 Harmony 源码
sudo apt install curl sudo apt install python3-pip sudo apt install git-lfs
安装下面这五个东西是为了解决编译到最后报错(头铁不信的你可以试试等最后再安装)
sudo apt install default-jdk sudo apt install mtd-utils sudo apt install scons sudo apt install gcc-arm-none-eabi sudo apt install gcc-arm-linux-gnueabi
2、安装 repo
务必按照此步骤安装repo。ubuntu默认提供的repo每次启动都会访问googlge服务器会被墙。 此外20.04下需要root身份执行–否则提示没权限。 curl https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 /usr/local/bin/repo chmod ax /usr/local/bin/repo pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests
3、下载源码
[官网版本更新说明}(https://gitee.com/openharmony/docs/tree/master/zh-cn/release-notes)
目前最新为 4.0 版本内核基于 5.10老版本 2.x 1.x 已经停止维护内核基于 4.19
参考官网下载方式
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’
注意那个 4.0 之前没有 v以前的版本是有这个 v 的不然会初始化失败还有就是注意检查电脑是否断网了
4、下载编译依赖工具包
源码下载完成后进入根目录执行 bash build/prebuilts_download.sh
看你网速快慢我这大概20分钟下载完成后会多出 openharmony_prebuilts 文件夹
5、编译源码
./build.sh --product-name rk3568 --ccache
第一次编译前面阶段 2W 多个文件后面阶段 6W 多个文件整体时间看你电脑性能。
编译中间要是出错看提示就行少啥就自行安装比如这种
default-jdk is not installed. please install it. mtd-utils is not installed. please install it. scons is not installed. please install it. gcc-arm-none-eabi is not installed. please install it. gcc-arm-linux-gnueabi is not installed. please install it. Missing dependencies, please check! [OHOS INFO] Set cache size limit to 100.0 GB [OHOS INFO] generated build prop info to /hom
6、烧写固件(劝你先别烧写)
最终固件路径 out\rk3568\packages\phone\images\
里面文件和普通 rk3568 aosp 项目大差不差所以烧写方式也是一样的。
打开 rk 烧写工具选择加载配置选择 images 里的 config.cfg把对应的 image
都重新选择替换就行。想要看图的可以去参考这个OpenHarmony 入门
7、内核及驱动移植
没有任何修改编译后的固件肯定是无法在板子上跑起来的我这里修改了很长时间也没有搞定这里记录一下一些心得。
主要原因就是内核版本差异太大无法平行移植有些小伙伴直接整个 kernel 替换了就成功跑起来了。
3568 有些版本的内核用的是 4.19(我这里就是),而最新的 harmony 都是基于 5.10 了
harmony 内核源码修改路径 out\kernel\src_tmp\linux-5.10
你要是内核版本一致就可以直接替换所有文件然后稍微修改一下如下编译规则文件
out\kernel\src_tmp\linux-5.10\make-ohos.sh
替换原有 TOYBRICK_DTB 为你自己的比如 MY3568_DTB, 总共 4 处修改

修改内核编译指定使用刚刚的 MYBOARD3568替换原来 TB-RK3568X0
# eval $MAKE_OHOS_ENV ./make-ohos.sh TB-RK3568X0 $RAMDISK_ARG ${ENABLE_LTO_O0}
eval $MAKE_OHOS_ENV ./make-ohos.sh MYBOARD3568 $RAMDISK_ARG ${ENABLE_LTO_O0}
再次执行 ./build.sh --product-name rk3568 --ccache 重新编译
8、编译错误举例
错误1、内核版本差异dts 文件属性不兼容出现在 rk3568-dram-default-timing.dtsi 中 260 行去修改注释即可

错误2、修改的配置文件有问题

9、开机 logo 替换

device\board\hihope\rk3568\kernel\logo_kernel.bmp
10、一些常见路径
applications\standard 系统核心应用包括日历、电话、相机、联系人、Setting、SystemUI 等
out\kernel\src_tmp\linux-5.10 最终编译内核源码路径
out\kernel\OBJ\linux-5.10 内核源码编译 obj 路径
kernel\linux\linux-5.10 SDK自带原生 kernel 路径
device\board\hihope\rk3568 编译脚本路径
openharmony kernel 代码构成如下
①、SDK 自带原生 kernelkernel\linux\linux-5.10\
②、openharmony HDF驱动补丁包 hdf.patchkernel\linux\patches\linux-5.10\rk3568_patch\
③、方案商需求的内核补丁包 kernel.patchkernel\linux\patches\linux-5.10\rk3568_patch\
由1中kernel加上2、3中的patch组合成最终的kernel代码out\kernel\src_tmp\linux-5.10
该工作由 device\board\hihope\rk3568\kernel\build_kernel.sh完成
脚本每次执行会时开头都会删除 out\kernel\src_tmp\linux-5.10 目录重新组合生成。
