一、编译uboot
1. 获取uboot源码(2020.10版本)
下载链接:en.SOURCES-u-boot-stm32mp1-openstlinux-5-10-dunfell-mp1-21-11-17_tar.xz
下载后解压:
mv en.SOURCES-u-boot-stm32mp1-openstlinux-5-10-dunfell-mp1-21-11-17_tar.xz en.SOURCES-u-boot-stm32mp1-openstlinux-5-10-dunfell-mp1-21-11-17.tar.xz
tar -xvf en.SOURCES-u-boot-stm32mp1-openstlinux-5-10-dunfell-mp1-21-11-17.tar.xz
里面分为源码和patch文件:
u-boot-stm32mp-v2020.10-stm32mp-r2-r0 U-Boot installation directory
├── [*].patch ST patches to apply during the U-Boot preparation (see next chapter)
├── u-boot-stm32mp-v2020.10-stm32mp-r2 U-Boot source code directory
├── Makefile.sdk Makefile for the U-Boot compilation
├── README.HOW_TO.txt Helper file for U-Boot management: reference for U-Boot build
├── series List of all ST patches to apply
└── u-boot-stm32mp-v2020.10-stm32mp-r2-r0.tar.gz Tarball file of the U-Boot source code
解压源码:
tar -zxvf u-boot-stm32mp-v2020.10-stm32mp-r2-r0.tar.gz
The FIP artifacts directory is named FIP_artifacts:

2. 编译uboot
2.1. 编译前的准备
(1)OpenSTLinux SDK 必须安装;
(2)编译内核需要安装的包:
llibncurses、libncursesw dev package、libyaml-dev:
sudo apt-get install libncurses5-dev libncursesw5-dev libyaml-dev
(3)确保SDK环境变量生效:
source STM32MP15-Ecosystem-v3.1.0/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
2. 2. uboot源码打patch
cd u-boot-stm32mp-v2020.10-stm32mp-r2/
for p in `ls -1 ../*.patch`; do patch -p1 < $p; done
2.3. 编译uboot
配置普通启动版本:
make stm32mp15_basic_defconfig
编译:
配置编译DK2板设备树:
make DEVICE_TREE=stm32mp157c-dk2 all
编译完成:
二、编译内核
1. 获取内核源码
下载链接:en.SOURCES-kernel-stm32mp1-openstlinux-5.10-dunfell-mp1-21-11-17.tar.xz
下载后解压:
tar xvf en.SOURCES-kernel-stm32mp1-openstlinux-5.10-dunfell-mp1-21-11-17.tar.xz
里面分为源码和patch文件:
linux-stm32mp-5.10.61-r2 Linux kernel installation directory
├── [*].patch ST patches to apply during the Linux kernel preparation (see next chapter)
├── fragment-[*].config ST configuration fragments to apply during the Linux kernel configuration (see next chapter)
├── linux-5.10.61 Linux kernel source code directory
├── linux-5.10.61.tar.xz Tarball file of the Linux kernel source code
├── README.HOW_TO.txt Helper file for Linux kernel management: reference for Linux kernel build
└── series List of all ST patches to apply
解压源码:
tar xvf linux-5.10.61.tar.xz
2. 编译kernel
参考 README.HOW_TO.txt
文档。
2.1. 编译前的准备
(1)OpenSTLinux SDK 必须安装;
(2)编译内核需要安装的包:
llibncurses、libncursesw dev package、libyaml-dev:
sudo apt-get install libncurses5-dev libncursesw5-dev libyaml-dev
mkimage:
sudo apt-get install u-boot-tools
yaml (check dts):
sudo apt-get install libyaml-dev
(3)确保SDK环境变量生效:
source STM32MP15-Ecosystem-v3.1.0/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
2.2. 内核源代码打patch
cd linux-5.10.61/
for p in `ls -1 ../*.patch`; do patch -p1 < $p; done
2.3. 源码配置
方式:配置编译目录 (different of kernel source code directory)
创建build目录:
mkdir -p ../build
生成默认配置文件.config:
make ARCH=arm O="$PWD/../build" multi_v7_defconfig fragment*.config
循环应用 fragment*.config
文件(搞不懂干啥的,执行了之后编译会出错,所以不要执行):
for f in `ls -1 ../fragment*.config`; do scripts/kconfig/merge_config.sh -m -r -O $PWD/../build $PWD/../build/.config $f; done
yes '' | make ARCH=arm oldconfig
2.4. 编译源码
编译内核:
make ARCH=arm uImage vmlinux dtbs LOADADDR=0xC2000040 O="$PWD/../build"
编译完成:
编译模块:
make ARCH=arm modules O="$PWD/../build"
