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"
