1 - 环境准备

  官方使用ubuntu16.04，笔者使用的环境为ubuntu18.04。建议读者使用这两个版本。
  请不要加载任何交叉工具链，避免编译出错。

2 - 资源准备

  PanGu板yocto资源可以访问如下链接：PanGu资料

  下载到的资源放在~/PanGu/目录下：


  i2som-pangu-yocto-predownload是Yocto在编译期间默认下载需要的软件包的目录。直接解压这个包，可以节省下载时间。
  i2som-pangu-sstate-cache是Yocto在编译时使用的软件包校验信息目录。直接解压这个包，可以节省下载时间。

3 - 解压

  输入如下命令进行解压：

xinluyao@ubuntu:~/PanGu$ tar xvf i2som-pangu-predownload.tar.xz
xinluyao@ubuntu:~/PanGu$ tar xvf i2som-pangu-sstate-cache.tar.xz
xinluyao@ubuntu:~/PanGu$ tar xvzf i2SOM-ST-Yocto.tar.gz
xinluyao@ubuntu:~/PanGu$ tar xvzf linux-st.tar.gz
xinluyao@ubuntu:~/PanGu$ tar xvzf u-boot-st.tar.gz
xinluyao@ubuntu:~/PanGu$ tar xvzf arm-trusted-firmware.tar.gz
xinluyao@ubuntu:~/PanGu$ tar xvf i2SOM-ST-Yocto.tar.gz

4 - DISTRO

xinluyao@ubuntu:~/PanGu$ cd i2SOM-ST-Yocto/
xinluyao@ubuntu:~/PanGu/i2SOM-ST-Yocto$ DISTRO=openstlinux-eglfs MACHINE=pangu source layers/meta-i2som-styocto/scripts/envsetup.sh

  ''DISTRO=openstlinux-eglfs MACHINE=pangu source layers/meta-i2som-styocto/scripts/envsetup.sh"是初始化Yocto的构建目录，执行后会自动创建"build-openstlinuxeglfs-pangu"目录，并自动切换到"build-openstlinuxeglfs-pangu"目录 且 加载环境变量。

  执行命令后效果如下图：

5 - 构建qt系统

  使用bitbake命令开始构建qt系统：

xinluyao@ubuntu:~/PanGu/i2SOM-ST-Yocto/build-openstlinuxeglfs-pangu$ bitbake i2som-image-qt

  执行上述命令后，构建系统如下图所示：

  笔者电脑是Ryzen 3700(8核16线程)，16G内存。给虚拟机分配8线程8G内存，整个构建大概花费2个小时。

6 - 报错与解决方案

1 - linux-i2som_4.19.bb

  报错的意思是查找内核源代码相关部分出错，请详细检查recipes-kernel/linux/linux-i2som_4.19.bb文件：

SRC_URI = "git:///${HOME}/PanGu/linux-st;protocol=file;branch=v${LINUX_VERSION}-r1.4-pangu;name=linux"
SRCREV = "ef13b6fb251d52984793d3aba4c9d19f822047c4"
SRCREV_FORMAT = "linux"
PV = "${LINUX_VERSION}+github+${SRCPV}"

2 - worker process exited unexpectedly

  这个错误可以编辑i2SOM-ST-Yocto/build-openstlinuxeglfs-pangu/conf/local.conf文件夹，在文件最后加上如下内容：

BB_NUMBER_THREADS = "6"

3 - 不明报错

  遇到其它报错，可以尝试先清除构建：

bitbake package -c clean

  package是报错的菜谱名，清除后可以尝试重新编译：

bitbake i2som-image-qt
