本篇在上篇的基础上继续搭建Qt的交叉编译环境实现Qt程序在Ubuntu中编译在STM32MP157板子中运行。
1 编译安装SDK
在上篇编译系统镜像的基础上继续编译和安装SDK。
1.1 编译SDK
执行如下执指令编译带有Qt功能的SDK:
bitbake st-example-image-qtwayland -c populate_sdk中途如果报do_fetch失败的错误可参考上篇编译镜像时的do_fetch失败的解决方法。
最终编译成功的结果如下 对应的打印如下

xxpcbxxpcb-ubuntu20:~/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Distribution-Package/build-openstlinuxweston-stm32mp1$ 执行成功后会下deploy目录生成sdk目录如下 1.2 安装SDK
执行sdk中的脚本来安装SDK到指定目录我的是安装到Developer-Package/SDK目录
./tmp-glibc/deploy/sdk/st-example-image-qtwayland-openstlinux-weston-stm32mp1-x86_64-toolchain-4.2.1-snapshot.sh -y -d /home/xxpcb/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK对应的打印如下

ST OpenSTLinux - Weston - (A Yocto Project Based Distro) SDK installer version 4.2.1-snapshotYou are about to install the SDK to /home/xxpcb/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK. Proceed [Y/n]? Y
Extracting SDK.................................................................................................................................................................................................................................................................................................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.$ . /home/xxpcb/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
xxpcbxxpcb-ubuntu20:~/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Distribution-Package/build-openstlinuxweston-stm32mp1$ 安装完成后可以在对应的目录中看到相关的文件 2 交叉编译Qt
在刚才指定安装SDK的目录中自带了许多Qt的例子可以使用交叉编译器来编译一个Qt程序试一下比如
cd ~/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK/sysroots/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi/usr/share/examples/gui
. ~/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
qmake make编译成功的打印如下 最后编译出analogclock可执行文件可以用file指令看下文件类型。
3 在板子中运行Qt
将analogclock文件拷贝到了STM32MP157D-DK1开发板中运行程序可以看到一个时钟的显示效果如下图 4 总结
本篇介绍了STM32MP157D-DK1开发板Qt程序交叉编译环境的搭建过程并通过一个实际的Qt程序编译后在板子中实际运行测试验证Qt编译环境的可用性。
