Create Standalone SDK from imx

###### tags: `TSC` `Linux` Create Standalone SDK from imx ===== # 前言 ## Key component 要讓 CPU 跑 linux 基本要有幾個組件 - Bootloader - Kernel - rootfs ### Bootloader ![](https://i.imgur.com/g5OZHb0.png) ### Files and binaries required in the boot partition: • flash.bin: Fit image containing U-Boot and the ATF • zImage: Kernel image • zImage-*.dtb: Device tree # Pre Setup :::danger 注意事項: 1. 編譯Yocto Project 官方文件提到 Linux Host 機器，硬碟空間至少要 ==120 GB== 2. 使用虛擬機(VM)建構硬碟/linux Host時，建議使用==固定大小==，不要使用動態分配 3. 建議使用 Ubuntu 18.04 or 相同的host linux 版本 ref: ![](https://i.imgur.com/PtaEt9K.png) ::: ## 安裝相依套件 ```bash= sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \ build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \ xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \ pylint3 xterm rsync curl libncursesw5-dev libncurses5-dev ``` ## 配置 Git ```bash= git config --global user.name "<Your Name>" git config --global user.email "<Your Email>" git config --list ``` ## 配置 repo utility - Create a bin folder in the home directory. ```bash= mkdir ~/bin curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo chmod a+x ~/bin/repo ``` - Add the following line to the .bashrc file to ensure that the ~/bin folder is in your PATH variable. ```bash= export PATH=~/bin:$PATH > ~/.bashrc source ~/.bashrc ``` # 建立 Toolchain (使用 Yocto Project) 1. 建立 Yocto Project on imx-5.10.52-2.1.0 ```bash= mkdir imx-yocto-bsp cd imx-yocto-bsp repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-hardknott -m imx-5.10.52-2.1.0.xml repo sync ``` 2. 建立yocto 設定檔 ``` usage: DISTRO=<distro name> MACHINE=<machine name> source imx-setup-release.sh -b <build dir> ``` - imx8mp-lpddr4-evk ```bash= DISTRO=fsl-imx-xwayland MACHINE=imx8mp-lpddr4-evk source imx-setup-release.sh -b imx8mp_build_xwayland ``` - imx8mmevk ```bash= DISTRO=fsl-imx-xwayland MACHINE=imx8mmevk source imx-setup-release.sh -b imx8mmevk_build_xwayland ``` :::info 執行會進行 EULA 簽署，輸入 y 即可 ![](https://i.imgur.com/P8vsaOI.png) > distro name: * fsl-imx-wayland : Wayland weston graphics. * fsl-imx-xwayland : Wayland graphics and X11. X11 applications using EGL are not supported. * ~~fsl-imx-fb : Frame Buffer graphics - no X11 or Wayland. Frame Buffer is not supported on i.MX 8.~~ > machine name: i.MX 8 * imx8qmmek * imx8qxpc0mek * imx8mqevk * imx8mm-lpddr4-evk * imx8mm-ddr4-evk * imx8mn-lpddr4-evk * imx8mn-ddr4-evk - [x] ==imx8mp-lpddr4-evk== * imx8mp-ddr4-evk * imx8dxl-lpddr4-evk * imx8mnddr3levk * imx8ulp-lpddr4-evk * imx8mmddr3lval ==> 編譯失敗 > 其他config 定義至 source/meta-xxx/conf/machine 的 xxx.conf example: imx8mmddr3lval in "/sources/meta-imx/meta-bsp/conf/machine" Restarting a build environment > If a new terminal window is opened or the machine is rebooted after a build directory is set up, the setup environment script should be used to set up the environment variables and run a build again. The full imx-setup-release.sh is not needed. ``` source setup-environment <build-dir> ``` ::: 3. 執行 bitbake > ==這個步驟需要等待 4~5 小時== - imx8mpevk ```bash= DISTRO=fsl-imx-xwayland MACHINE=imx8mp-lpddr4-evk bitbake imx-image-core -c populate_sdk ``` - imx8mmevk ```bash= DISTRO=fsl-imx-xwayland MACHINE=imx8mmevk bitbake imx-image-core -c populate_sdk ``` :::info 最後會在 ==tmp/deploy/sdk== 目錄下會產出 `fsl-xxxx.sh` (toolchain install Script file) ::: 4. 安裝 toolchain 執行 toolchain install script file example: ```bash= . /home/max/imx-yocto-bsp/imx8mp_build_xwayland/tmp/deploy/sdk/fsl-imx-xwayland-glibc-x86_64-core-image-minimal-cortexa53-crypto-imx8mpevk-toolchain-5.10-hardknott.sh ``` ![](https://i.imgur.com/qsTvnCP.png) :::info 預設安裝置 /opt 下 ::: 5. Start build environment run environment-setup script ```bash= . /opt/fsl-imx-xwayland/5.10-hardknott/environment-setup-cortexa53-crypto-poky-linux ``` or use source ```bash= source /opt/fsl-imx-xwayland/5.10-hardknott/environment-setup-cortexa53-crypto-poky-linux ``` 6. 確認 toolchain 是否安裝成功 ``` echo &env | grep -e ARCH= -e CROSS_COMPILE= -e SYSROOT= -e CC= ``` ![](https://i.imgur.com/cWmoEXV.png) :::warning 由於sdk 採用動態設定環境變數，若充新開啟 terminal ，請重新執行 'run environment-setup script ::: # 建立 Bootloader Bootloader 包含以下組件: - 1.
