一、獲取軟件倉庫
$ 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執(zhí)行第3條命令時(shí)報(bào)錯(cuò)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按照提示安裝git-repo后重新執(zhí)行命令，報(bào)錯(cuò)如下：
$ repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-21-12-22 warning: gpg (GnuPG) is not available. warning: Installing it is strongly encouraged. warning: templates not found /build/git-repo-publish/parts/git/install/usr/share/git-core/templates ......File "/home/admin/samba/stm32mp157/STM32MP15-Ecosystem-v2.1.0/Distribution-Package/openstlinux-5.4-dunfell-mp1-21-12-22/.repo/repo/main.py", line 79file=sys.stderr)^ SyntaxError: invalid syntax按照如下步驟解決上述錯(cuò)誤：
$ sudo apt-get install gpg $ rm -rf ~/.repoconfig $ mkdir -p ~/bin $ curl https://storage.googleapis.com/git-repo-downloads/repo-1 > ~/bin/repo $ chmod a+x ~/bin/repo然后執(zhí)行如下命令獲取倉庫：
$ python3 ~/bin/repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-21-12-22如果出現(xiàn)如下警告，按照提示執(zhí)行命令即可：

二、初始化構(gòu)建環(huán)境
我選擇的鏡像是QT image and SDK with weston/wayland，因此執(zhí)行如下命令來初始化構(gòu)建環(huán)境：
$ DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh由于我的主機(jī)缺少相關(guān)軟件包提示如下：

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，構(gòu)建環(huán)境初始化完成，接下來開始構(gòu)建鏡像和SDK。
三、構(gòu)建鏡像和SDK
溫馨提示：在執(zhí)行下面的構(gòu)建命令前建議查看下磁盤容量以確保有足夠的磁盤空間，否則在構(gòu)建過程中因磁盤空間不足也會導(dǎo)致失敗，如果磁盤空間不夠需要先進(jìn)行擴(kuò)容再來進(jìn)行構(gòu)建工作。
鏡像和SDK構(gòu)建完成后的磁盤占用情況如下：
$ du -h -d 1 134M ./layers 330M ./.repo 70G ./build-openstlinuxweston-stm32mp1執(zhí)行如下命令開始構(gòu)建鏡像：
$ bitbake st-example-image-qtwayland然后就是耐心等待構(gòu)建完成。如果在該過程中由于下載出錯(cuò)等原因?qū)е轮袛?#xff0c;重新執(zhí)行構(gòu)建命令即可。

補(bǔ)充： OpenSTLinux提供了兩種基于QT的鏡像和SDK，這兩種鏡像和SDK的構(gòu)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 -
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
四、適配開發(fā)板
前面已經(jīng)編譯完成鏡像和SDK，已經(jīng)確保整個(gè)過程是沒有問題的。接下來就可以修改tf-a、u-boot和linux適配自己的開發(fā)板了，這些工作均在編譯目錄openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1進(jìn)行。
4.1 修改TF-A
執(zhí)行如下命令查找TF-A recipe：
$ devtool search tf-a*結(jié)果如下：
NOTE: Starting bitbake server... NOTE: Reconnecting to bitbake server... NOTE: Retrying server connection (#1)... NOTE: Started PRServer with DBfile: /home/admin/samba/stm32mp157/Distribution-Package/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/cache/prserv.sqlite3, IP: 127.0.0.1, PORT: 34083, PID: 252954 Loading cache: 100% |#############################################################################| Time: 0:00:01 Loaded 3751 entries from dependency cache. ...... tf-a-stm32mp Trusted Firmware-A for STM32MP1 ...... tf-a-stm32mp-serialboot Trusted Firmware-A for STM32MP1 as serial boot loader ...... tf-a-stm32mp-ssp Trusted Firmware-A SSP for STM32MP1 ......如果出現(xiàn)如下錯(cuò)誤：
ERROR: Unable to start bitbake server (None) ERROR: Server log for this session ...... ERROR: The following layer directories do not exist ...... ERROR: Please check BBLAYERS in ......解決方法：
$ source ../layers/openembedded-core/oe-init-build-env然后根據(jù)查找到的recipe名稱執(zhí)行如下命令：
$ devtool modify tf-a-stm32mp命令執(zhí)行完成后會生成workspace目錄，然后進(jìn)入目錄workspace/sources/tf-a-stm32mp對tf-a源碼進(jìn)行修改，參考STM32MP157系統(tǒng)移植(TF-A,U-Boot,Linux)文章的TF-A移植部分。
這里需要注意的是，如果是要?jiǎng)?chuàng)建自己的開發(fā)板設(shè)備樹文件則需要修改配置文件，否則無法編譯出對應(yīng)的固件。例如我需要添加自己的開發(fā)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文件如下內(nèi)容，在其中添加自己的開發(fā)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"當(dāng)然直接修改源碼中現(xiàn)有的設(shè)備樹文件是最方便的，就無需再去修改配置文件了。例如我手中的開發(fā)板是參考stm32mp157d-ev1設(shè)計(jì)，那就直接修改源碼中stm32mp157d-ev1.dts及其相關(guān)文件就行了（個(gè)人更推薦這種做法，維持非自己創(chuàng)建的layer完整性）。
修改完成后執(zhí)行如下命令進(jìn)行編譯：
$ devtool build tf-a-stm32mp編譯成功后在目錄workspace/sources/tf-a-stm32mp/oe-workdir/deploy-tf-a-stm32mp下就是編譯出的固件。然后執(zhí)行如下命令部署：
$ bitbake tf-a-stm32mp -c deploy部署后在/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/deploy/images/stm32mp1/arm-trusted-firmware目錄下可以看到更新固件。
接下來對tf-a-stm32mp-serialboot進(jìn)行修改，和上面步驟一樣：
$ devtool modify tf-a-stm32mp-serialboot $ devtool build tf-a-stm32mp-serialboot $ bitbake tf-a-stm32mp-serialboot -c deploy4.2 修改U-Boot
執(zhí)行如下命令查找U-boot recipe：
$ devtool search u-boot*結(jié)果如下：
NOTE: Starting bitbake server... NOTE: Reconnecting to bitbake server... NOTE: Retrying server connection (#1)... NOTE: Started PRServer with DBfile: /home/admin/samba/stm32mp157/Distribution-Package/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/cache/prserv.sqlite3, IP: 127.0.0.1, PORT: 36991, PID: 371338 Loading cache: 100% |#############################################################################| Time: 0:00:01 Loaded 3749 entries from dependency cache.

$ devtool modify u-boot-stm32mp命令執(zhí)行完成后進(jìn)入目錄workspace/sources/u-boot-stm32mp對u-boot源碼進(jìn)行修改，參考STM32MP157系統(tǒng)移植(TF-A,U-Boot,Linux)文章的U-BOOT移植部分。
注意：《STM32MP157系統(tǒng)移植(TF-A,U-Boot,Linux)》文章的u-boot代碼和本文并非完全一樣，本文修改ðernet0節(jié)點(diǎn)不同之處如下所示：
ðernet0 {......pinctrl-1 = <ðernet0_rgmii_pins_sleep_a>;...... };修改完成后執(zhí)行如下命令進(jìn)行編譯：
$ devtool build u-boot-stm32mp如果編譯報(bào)錯(cuò)就看下輸出日志里面有沒如下提示文本：
/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' in the '/home/admin/samba/stm32mp157/Distribution-Package/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/workspace/sources/u-boot-stm32mp' directory.若有就按提示進(jìn)入u-boot-stm32mp目錄下執(zhí)行 make mrproper命令：
$ make mrproper CLEAN u-boot.cfg.tmp CLEAN scripts/basic CLEAN scripts/kconfig CLEAN include/config include/generated然后回到build-openstlinuxweston-stm32mp1目錄重新執(zhí)行編譯指令。
同樣，若重新構(gòu)建image過程中遇到uboot報(bào)錯(cuò)在openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/work-shared/stm32mp1/uboot-source目錄執(zhí)行make mrproper命令然后回到build-openstlinuxweston-stm32mp1目錄重新執(zhí)行構(gòu)建指令
編譯成功后在目錄workspace/sources/u-boot-stm32mp/oe-workdir/deploy-u-boot-stm32mp下就是編譯出的固件。然后執(zhí)行如下命令部署：
$ bitbake u-boot-stm32mp -c deploy部署后在/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/deploy/images/stm32mp1/bootloader目錄下可以看到更新固件。
4.3 修改Linux

如果需要執(zhí)行menuconfig對內(nèi)核配置進(jìn)行更改則執(zhí)行如下命令：
$ bitbake virtual/kernel -c menuconfig修改完成后執(zhí)行如下命令進(jìn)行編譯：
# devtool build linux-stm32mp # bitbake linux-stm32mp -c deploy $ bitbake virtual/kernel -C compile編譯完成后在/openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/tmp-glibc/deploy/images/stm32mp1/kernel目錄下可以看到新的固件。
上面命令會執(zhí)行configure、compile、package、deploy等一系列命令，比較耗時(shí)間，如果只是想單純編譯可以執(zhí)行如下命令：
$ bitbake virtual/kernel -c compile編譯后固件在openstlinux-5.4-dunfell-mp1-21-12-22/build-openstlinuxweston-stm32mp1/workspace/sources/linux-stm32mp/oe-workdir/build目錄。
最后，將這些固件更新到開發(fā)板后就可以搭配編譯出來的帶Qt的文件系統(tǒng)進(jìn)行驗(yàn)證3D-GPU等功能了。
五、補(bǔ)充
5.1 關(guān)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 {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擁有三個(gè)SDMMC接口，在芯片中的內(nèi)存映射地址如下：
| SDMMC1 | 0x58005000 - 0x58005FFF | 4 KB |
| SDMMC2 | 0x58007000 - 0x58007FFF | 4 KB |
| SDMMC3 | 0x48004000 - 0x480043FF | 1 KB |
根據(jù)地址分配可知它們的初始化順序是SDMMC3 --> SDMMC1 --> SDMMC2。
三個(gè)接口都啟用后在Linux中對應(yīng)的操作文件如下：
| /dev/mmcblk1 | /dev/mmcblk2 | /dev/mmcblk0 |
我手上的開發(fā)板對這3個(gè)接口分配如下：
| SD卡 | EMMC | WIFI |
在Linux設(shè)備樹中啟用sdmmc3接口前后sd卡和emmc設(shè)備號的變化如下：
| SD卡 | mmc0 | mmc1 |
| EMMC | mmc1 | mmc2 |
st提供的yocto源碼中沒有使用sdmmc3，所以啟用了sdmmc3接口后需要修改一些配置文件，系統(tǒng)啟動(dòng)后才能正常掛載文件系統(tǒng)。需要修改如下幾個(gè)文件：
mount-partitions.sh
OpenSTLinux源碼中的位置：openstlinux-5.4-dunfell-mp1-21-12-22/layers/meta-st/meta-st-openstlinux/recipes-core/systemd/systemd-mount-partitions/mount-partitions.sh
燒錄后在文件系統(tǒng)中的位置：/sbin/mount-partitions.sh
修改后內(nèi)容如下，主要增加了mmcblk2的內(nèi)容：
