编译SDK

编译SSD202 SDK

编译uboot

  • 环境配置

    export ARCH="arm"
    export CROSS_COMPILE=arm-linux-gnueabihf-
    
  • 选取机型相关config

    # 配置文件目录 ssd20x-uboot-open/configs,编译WT2022
    make WT2022_defconfig
    
  • 编译

    make clean
    make -j4
    
  • 替换烧录镜像

    cp ${SDK_PATH}/ssd20x-uboot-open/u-boot_spinand.xz.img.bin ${SDK_PATH}/ssd20x-images-open/WT2022/boot/u-boot_spinand.xz.img.bin
    cp ${SDK_PATH}/ssd20x-uboot-open/u-boot_spinand.xz.img.bin ${SDK_PATH}/ssd20x-images-open/WT2022/uboot_s.bin
    
  • flash选型

    cd ${SDK_PATH}/ssd20x-images-open/partition
    ./part.sh # 默认为128MB(1Gbit)flash配置,256MB(2GBit)flash需传入2G参数
    cp cis.bin ${SDK_PATH}/ssd20x-images-open/WT2022

编译kernel

  • 环境配置

    export ARCH="arm"
    export CROSS_COMPILE=arm-linux-gnueabihf-
    
  • 选取机型config

    #配置文件目录 ssd20x-kernel-open/arch/arm/configs
    cd ${SDK_PATH}/ssd20x-kernel-open
    make WT2022_defconfig
    
  • 编译

    make clean
    make -j4
    
  • 替换烧录镜像

    cp ./arch/arm/boot/uImage.xz ${SDK_PATH}/ssd20x-images-open/WT2022/kernel
    

制作文件系统

  • ubi分区文件系统在ssd20x-rootfs-open/ssd20x目录下,只需解压缩文件系统,添加客制化软件即可生效功能,无需二次编译系统镜像,以在ssd202添加应用为例:

    cd ${SDK_PATH}/ssd20x-rootfs-open/ssd202
    tar zxvf root-sstar.tar.gz  # root-sstar.tar.gz为编译openwrt生成的root-sstar
    cp ${Youer_Files} ${SDK_PATH}/ssd20x-rootfs-open/ssd202/root-sstar/usr
    
  • 添加好文件后,执行对应分区文件系统的打包脚本

    sudo apt-get install mtd-utils # 打包依赖mtd-utils,需提前安装此工具
    cd ${SDK_PATH}/ssd20x-rootfs-open
    ./mk_tools.sh
    ./mk_ubi.sh ssd202
    
  • 替换

    mv root.ubi ${SDK_PATH}/ssd20x-images-open/WT2022
    

编译openwrt

  • 如果需要openwrt支持额外软件功能,则需要编译sdk,替换镜像,单纯做UI开发或者驱动开发则无需执行此步骤:

    #获取openwrt源码
    git clone https://gitee.com/qiming-zhixian/ssd2xx-openwrt-open.git
    cd ssd2xx-openwrt-open
    git clone https://gitee.com/qiming-zhixian/ssd20x-kernel-open.git
    cd 18.06
    #更新下载软件包列表feeds
    export GIT_SSL_NO_VERIFY=1
    ./scripts/feeds update -a
    ./scripts/feeds install -a
    #生效适配好的机型配置 -> 18.06/wtconfig/WT2xxx
    make WT2022_wt
    #编译, 生成镜像路径18.06/bin/targets/sstar/ssd20x/WT2022
    make V=s -j4
    #替换烧录镜像
    cp bin/targets/sstar/ssd20x/WT2022/WT2022-uImage.xz ${SDK_PATH}/ssd20x-images-open/WT2022/kernel
    cp bin/targets/sstar/ssd20x/WT2022/WT2022-root-ubi.img ${SDK_PATH}/ssd20x-images-open/WT2022/root.ubi
