记录下整个过程以及在该过程中遇到的问题和解决方法。

一、获取软件仓库

$ mkdir -p openstlinux-5.4-dunfell-mp1-21-12-22
$ cd openstlinux-5.4-dunfell-mp1-21-12-22
$ repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-21-12-22 

  • 1
  • 2
  • 3

执行第3条命令时报错如下：

$ repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-21-12-22 

Command 'repo' not found, but can be installed with:

sudo snap install git-repo

然后执行如下命令获取仓库：

$ python3 ~/bin/repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-21-12-22 

  • 1

如果出现如下警告，按照提示执行命令即可：

... A new version of repo (2.21) is available.
... You should upgrade soon:
    cp /home/admin/samba/stm32mp157/STM32MP15-Ecosystem-v2.1.0/Distribution-Package/openstlinux-5.4-dunfell-mp1-21-12-22/.repo/repo/repo /home/admin/bin/repo

  • 1

接下来进行构建环境的初始化。

二、初始化构建环境

我选择的镜像是QT image and SDK with weston/wayland，因此执行如下命令来初始化构建环境：

$ DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh

  • 1

由于我的主机缺少相关软件包提示如下：

[HOST DISTRIB check]
Linux Distrib: Ubuntu
Linux Release: 20.04

Required packages for Linux Distrib:
build-essential chrpath cpio debianutils diffstat gawk gcc-multilib git iputils-ping libegl1-mesa libsdl1.2-dev libssl-dev pylint python3 python3-git python3-jinja2 python3-pexpect python3-pip socat texinfo unzip wget xterm xz-utils

Missing required packages detected:
chrpath diffstat gawk gcc-multilib libegl1-mesa libsdl1.2-dev pylint python3-git python3-jinja2 python3-pip socat texinfo xterm

To update your Linux Distribution packages, two proposals:
  1) run again envsetup.sh script with '--pkg-update' option
  OR
  2) before running envsetup.sh script, launch first in your Linux console:
sudo apt-get update
sudo apt-get install chrpath diffstat gawk gcc-multilib libegl1-mesa libsdl1.2-dev pylint python3-git python3-jinja2 python3-pip socat texinfo xterm

然后在我的主机上会出现如下错误：

下列软件包有未满足的依赖关系：
 libsdl1.2-dev : 依赖: libglu1-mesa-dev 但是它将不会被安装 或
                         libglu-dev
                 依赖: libx11-dev 但是它将不会被安装
                 依赖: libxext-dev 但是它将不会被安装
E: 无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系。

  • The OpenEmbedded environment setup script must be run once in each new working terminal in which you use the BitBake or devtool tools

  • The BSP for STM32MP1 depends on packages and firmwares which are covered by a software license agreement (SLA). You will be asked to read and to accept this EULA.

至此，构建环境初始化完成，接下来开始构建镜像和SDK。

三、构建镜像和SDK

温馨提示：在执行下面的构建命令前建议查看下磁盘容量以确保有足够的磁盘空间，否则在构建过程中因磁盘空间不足也会导致失败，如果磁盘空间不够需要先进行扩容再来进行构建工作。

镜像和SDK构建完成后的磁盘占用情况如下：

$ du -h -d 1
134M    ./layers
330M    ./.repo
70G     ./build-openstlinuxweston-stm32mp1

  • 1
  • 2
  • 3
  • 4

执行如下命令开始构建镜像：

$ bitbake st-example-image-qtwayland

  • 1

然后就是耐心等待构建完成。如果在该过程中由于下载出错等原因导致中断，重新执行构建命令即可。

镜像和SDK构建完成后分别存放在目录openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/deploy下的images和sdk目录下。

补充： OpenSTLinux提供了两种基于QT的镜像和SDK，这两种镜像和SDK的构建命令如下：

  • QT image and SDK with EGLFS

    # Initialize the OpenEmbedded build environment for the openstlinux-eglfs distro:
$ DISTRO=openstlinux-eglfs MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh
# Build the image and the SDK:
$ bitbake st-example-image-qt
$ bitbake st-example-image-qt -c populate_sdk

    • 3
    • 4
    • 5

  • QT image and SDK with weston/wayland

    # Initialize the OpenEmbedded build environment for the openstlinux-weston distro:
$ DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh
# Build the image and the SDK:
$ bitbake st-example-image-qtwayland
$ bitbake st-example-image-qtwayland -c populate_sdk

    • 3
    • 4

四、适配开发板

前面已经编译完成镜像和SDK，已经确保整个过程是没有问题的。接下来就可以修改tf-a、u-boot和linux适配自己的开发板了，这些工作均在编译目录openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1进行。

4.1 修改TF-A

执行如下命令查找TF-A recipe：

$ devtool search tf-a*

解决方法：

$ source ../layers/openembedded-core/oe-init-build-env

  • 1

然后根据查找到的recipe名称执行如下命令：

$ devtool modify tf-a-stm32mp

  • 1

命令执行完成后会生成workspace目录，然后进入目录workspace/sources/tf-a-stm32mp对tf-a源码进行修改，参考STM32MP157系统移植(TF-A,U-Boot,Linux)文章的TF-A移植部分。

这里需要注意的是，如果是要创建自己的开发板设备树文件则需要修改配置文件，否则无法编译出对应的固件。例如我需要添加自己的开发板stm32mp157d-custom，需要做如下修改：

修改openstlinux-5.4-dunfell-mp1-21-12-22/layers/meta-st/meta-st-stm32mp/conf/machine/stm32mp1.conf文件如下内容，在其中添加自己的开发板：

# =========================================================================
# Machine settings
# =========================================================================
# Define list of devicetree per board
STM32MP_DT_FILES_DK += "stm32mp157a-dk1 stm32mp157d-dk1"
STM32MP_DT_FILES_DK += "stm32mp157c-dk2 stm32mp157f-dk2"
STM32MP_DT_FILES_ED += "stm32mp157c-ed1 stm32mp157f-ed1"
STM32MP_DT_FILES_EV += "stm32mp157a-ev1 stm32mp157c-ev1 stm32mp157d-ev1 stm32mp157f-ev1 stm32mp157d-custom"

当然直接修改源码中现有的设备树文件是最方便的，就无需再去修改配置文件了。例如我手中的开发板是参考stm32mp157d-ev1设计，那就直接修改源码中stm32mp157d-ev1.dts及其相关文件就行了（个人更推荐这种做法，维持非自己创建的layer完整性）。

修改完成后执行如下命令进行编译：

$ devtool build tf-a-stm32mp

  • 1

编译成功后在目录workspace/sources/tf-a-stm32mp/oe-workdir/deploy-tf-a-stm32mp下就是编译出的固件。然后执行如下命令部署：

$ bitbake tf-a-stm32mp -c deploy

  • 1

部署后在/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/deploy/images/stm32mp1/arm-trusted-firmware目录下可以看到更新固件。

接下来对tf-a-stm32mp-serialboot进行修改，和上面步骤一样：

$ devtool modify tf-a-stm32mp-serialboot
$ devtool build tf-a-stm32mp-serialboot
$ bitbake tf-a-stm32mp-serialboot -c deploy

命令执行完成后进入目录workspace/sources/u-boot-stm32mp对u-boot源码进行修改，参考STM32MP157系统移植(TF-A,U-Boot,Linux)文章的U-BOOT移植部分。

注意：《STM32MP157系统移植(TF-A,U-Boot,Linux)》文章的u-boot代码和本文并非完全一样，本文修改&ethernet0节点不同之处如下所示：

&ethernet0 {

	pinctrl-1 = <&ethernet0_rgmii_pins_sleep_a>;
	......
};

修改完成后执行如下命令进行编译：

$ devtool build u-boot-stm32mp

  • 1

如果编译报错就看下输出日志里面有没如下提示文本：

/home/admin/samba/stm32mp157/Distribution-Package/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/workspace/sources/u-boot-stm32mp is not clean, please run 'make mrproper'

然后回到build-openstlinuxweston-stm32mp1目录重新执行编译指令。

同样，若重新构建image过程中遇到uboot报错在openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/work-shared/stm32mp1/uboot-source目录执行make mrproper命令然后回到build-openstlinuxweston-stm32mp1目录重新执行构建指令

编译成功后在目录workspace/sources/u-boot-stm32mp/oe-workdir/deploy-u-boot-stm32mp下就是编译出的固件。然后执行如下命令部署：

$ bitbake u-boot-stm32mp -c deploy

  • 1

部署后在/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/deploy/images/stm32mp1/bootloader目录下可以看到更新固件。

4.3 修改Linux

首先执行如下命令进行初始化：

$ devtool modify virtual/kernel

命令执行完成后进入目录workspace/sources/linux-stm32mp对linux源码进行修改，参考STM32MP157系统移植(TF-A,U-Boot,Linux)文章的LINUX移植部分。

如果需要执行menuconfig对内核配置进行更改则执行如下命令：

$ bitbake virtual/kernel -c menuconfig

  • 1

修改完成后执行如下命令进行编译：

# devtool build linux-stm32mp
# bitbake linux-stm32mp -c deploy
$ bitbake virtual/kernel -C compile

  • 1
  • 2
  • 3

编译完成后在/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/deploy/images/stm32mp1/kernel目录下可以看到新的固件。

上面命令会执行configure、compile、package、deploy等一系列命令，比较耗时间，如果只是想单纯编译可以执行如下命令：

$ bitbake virtual/kernel -c compile

  • 1

编译后固件在openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/workspace/sources/linux-stm32mp/oe-workdir/build目录。

最后，将这些固件更新到开发板后就可以搭配编译出来的带Qt的文件系统进行验证3D-GPU等功能了。

五、补充

5.1 关于SDMMC3

The SDMMC instances are ordered by address in the device tree arch/arm/boot/dts/stm32mp151.dtsi file:

sdmmc3: sdmmc@48004000 {
...
sdmmc1: sdmmc@58005000 {
...
sdmmc2: sdmmc@58007000 {

  • 1
  • 2
  • 3
  • 4
  • 5

By default, in OpenSTLinux distribution, sdmmc3 is disabled so the sdmmc1 (SD card on Evaluation boards and Discovery kits) and sdmmc2 (eMMC on Evaluation boards and Wifi on Discovery kits) are respectively aliased to mmc0 and mmc1.
If you enable sdmmc3, it will take the mmc0 alias and the aliases above will shift, so don’t forget to update the Linux kernel boot command accordingly!
For instance, ‘root=/dev/mmcblk0p6’ will become ‘root=/dev/mmcblk1p6’ to mount the rootfs from the sdmmc1 (SD card) when sdmmc3 is enabled.

STM32MP157拥有三个SDMMC接口，在芯片中的内存映射地址如下：

PeripheralBoundary addressSize (Bytes)
SDMMC10x58005000 - 0x58005FFF4 KB
SDMMC20x58007000 - 0x58007FFF4 KB
SDMMC30x48004000 - 0x480043FF1 KB

根据地址分配可知它们的初始化顺序是SDMMC3 --> SDMMC1 --> SDMMC2。

三个接口都启用后在Linux中对应的操作文件如下：

SDMMC1SDMMC2SDMMC3
/dev/mmcblk1/dev/mmcblk2/dev/mmcblk0

我手上的开发板对这3个接口分配如下：

SDMMC1SDMMC2SDMMC3
SD卡EMMCWIFI

在Linux设备树中启用sdmmc3接口前后sd卡和emmc设备号的变化如下：

设备设备号（不使用SDMMC3）设备号（使用SDMMC3）
SD卡mmc0mmc1
EMMCmmc1mmc2

st提供的yocto源码中没有使用sdmmc3，所以启用了sdmmc3接口后需要修改一些配置文件，系统启动后才能正常挂载文件系统。需要修改如下几个文件：

  1. mount-partitions.sh

    OpenSTLinux源码中的位置：openstlinux-5.4-dunfell-mp1-21-12-22/layers/meta-st/meta-st-openstlinux/recipes-core/systemd/systemd-mount-partitions/mount-partitions.sh

    烧录后在文件系统中的位置：/sbin/mount-partitions.sh

    修改后内容如下，主要增加了mmcblk2的内容：

    #!/bin/sh -
