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WT2012
  make WT2012_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/WT2012/boot/u-boot_spinand.xz.img.bin
  cp ${SDK_PATH}/ssd20x-uboot-open/u-boot_spinand.xz.img.bin ${SDK_PATH}/ssd20x-images-open/WT2012/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/WT2012
  

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 WT2012_defconfig
  

• 编译

  make clean
  make -j4
  

• 替换烧录镜像

  cp ./arch/arm/boot/uImage.xz ${SDK_PATH}/ssd20x-images-open/WT2012/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ssd201添加应用为例：

  cd ${SDK_PATH}/ssd20x-rootfs-open/ssd201
  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/ssd201/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 ssd201
  

• 替换

  mv root.ubi ${SDK_PATH}/ssd20x-images-open/WT2012
  

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 WT2012_wt
  #编译, 生成镜像路径18.06/bin/targets/sstar/ssd20x/WT2012
  make V=s -j4
  #替换烧录镜像
  cp bin/targets/sstar/ssd20x/WT2012/WT2012-uImage.xz ${SDK_PATH}/ssd20x-images-open/WT2012/kernel
  cp bin/targets/sstar/ssd20x/WT2012/WT2012-root-ubi.img ${SDK_PATH}/ssd20x-images-open/WT2012/root.ubi
