    Official documentation

    • Download CSDTK4.2 (baidu cloud, MEGA cloud, direct link)
    • Get SDK from Github (pre-release V2.112)
    • Decompress the downloaded CSDTK file (e.g: C:\CSDTK)
    • Run config_env_admin.bat file in CSDTK to set environment variables
    • Decompress the CSDK downloaded file (e.g: C:\GPRS_C_SDK)
    • Open a PowerShell terminal into the CSDK folder and type .\build.bat app to build the app folder source code in debug mode

    Build command

    You can use ./build.bat script to build project:

    • ./build.bat $PROJ: compile app module,e.g.: ./build.batsh app to compile the source code of app folder
    • ./build.bat demo $PROJ: compile a demo project, e.g.: ./build.bat demo gpio to compile gpio demo
    • ./build.bat clean $PROJ: clear the build files of $PROJ
    • ./build.bat clean all: clear all the build files
    • ./build.bat demo $PROJ release: build a release version, e.g.: ./build.bat demo gpio release.

    By default, build.bat will build a debug version.

    In release mode, the watchdog resets the system after an error.

    A build and an hex folder will be generated after compile.

    Two hex file will be generated into the hex folder (*_B*.lod and *_flash.lod). The bigger file should be flashed after each SDK upgrade. The smaller one will contain the compiled source code and must be uploaded after compilation.
