  cd reCamera
  git submodule init
  git submodule update --depth 1

• Update Submodules (optional)

  ./scripts/repo_clone.sh --gitpull external/subtree.xml

2.3 Build

• Location of the ${project}_defconfig

  ls external/configs/
  sg2002_recamera_emmc_defconfig  sg2002_recamera_sd_defconfig  sg2002_xiao_sd_defconfig

• Building the Project

  make ${project}

  Example:

  make sg2002_recamera_emmc

• Location of the Build Targets

  ls -l output/${project}/install/soc_${project}/${project}

  Example:

  sg2002_reCamera_0.0.1_emmc_sd_compat.zip
  sg2002_reCamera_0.0.1_emmc.zip

2.4 Flashing

• Booting from eMMC (Example: sg2002_reCamera_0.0.1_emmc.zip)

  • Install windows driver: CviUsbDownloadInstallDriver.zip
  • Unzip the CviBurn_v2.0_cli_windows.zip package.
  • Unzip the package generated by Section 2.3, for example: ./output/sg2002_recamera_emmc/install/soc_sg2002_recamera_emmc/sg2002_reCamera_0.0.1_emmc.zip
  • Execute the following command in Windows (use [-m xx:xx:xx:xx:xx:xx] to configure the Ethernet MAC address): usb_dl.exe -c cv181x -s linux -i ..\sg2002_reCamera_0.0.1_emmc [-m xx:xx:xx:xx:xx:xx]

• SD Card recovery (Example: sg2002_reCamera_0.0.1_emmc_recovery.zip)

  • Use balenaEtcher to flash the sg2002_reCamera_0.0.1_emmc_recovery.zip file into the SD card.
  • Then insert the SD card into the board, and power on. It will automatically burn image into emmc.

• Booting from SD Card (Example: sg2002_reCamera_0.0.1_emmc_sd_compat.zip)

  • Use balenaEtcher to flash the sg2002_reCamera_0.0.1_emmc_sd_compat.zip file into the SD card.
  • Then insert the SD card into the board, and power on. The board will booting from SD card.

• OTA (Example: sg2002_reCamera_0.0.1_emmc_ota.zip)

  • This image is specifically designed for OTA updates via the WebUI.
