Hello,
The source code and the configuration for the M7 gateway application can be found under the <GoldVIP_install_dir>/configuration/can-gw/workspace. Please check the 12.3 (Building the M7 Application) chapter from the GoldVIP User Manual for steps on how to set up the environment required for customizing and building the gateway application.
The shell scripts are there to test the functionalities of the gateway app.
Best regards,
George
