SDK包含了构建OpenSTLinux所需的交叉编译工具链和库。
官方教程地址https://wiki.stmicroelectronics.cn/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP135x-DK/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Install_the_SDK
首先安装工具：
- sudo apt-get update
- sudo apt-get install gawk wget git diffstat unzip texinfo gcc-multilib chrpath socat cpio python3 python3-pip python3-pexpect
额外设置
- echo 'options mmc_block perdev_minors=16' > /tmp/mmc_block.conf
- sudo mv /tmp/mmc_block.conf /etc/modprobe.d/mmc_block.conf
下载得到en.SDK-x86_64-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.tar.gz
解压SDK
- cd $HOME/STM32MPU_workspace/tmp
- tar xvf en.SDK-x86_64-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.tar.gz
创建STM32MP1 Developer Package SDK目录，并执行SDK安装脚本
- mkdir -p $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/SDK
- chmod +x stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21/sdk/st-image-weston-openstlinux-weston-stm32mp1-x86_64-toolchain-4.2.1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.sh
- ./stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21/sdk/st-image-weston-openstlinux-weston-stm32mp1-x86_64-toolchain-4.2.1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.sh -d <working directory absolute path>/Developer-Package/SDK
安装成功后显示的信息如下：
- 1-x86_64-toolchain-4.2.1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.sh -d /home/ubuntu/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/SDK
- ST OpenSTLinux - Weston - (A Yocto Project Based Distro) SDK installer version 4.2.1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21

- You are about to install the SDK to "/home/ubuntu/STM32MPU_workspace/STM32MP1-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/ubuntu/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
每次打开终端使用SDK前执行命令加载环境变量
- <blockquote> cd $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package
检查是否加载成功，查看架构
