start-parodus is a C-based utility used in RDK platforms to initialize and generating the binary in BPI Platform. It acts as a wrapper that handles system readiness checks, configuration loading, URL preparation, and command execution for starting Parodus. This component sets up the environment and starts Parodus (webpa). Parodus is a websocket client which connects to a server in the cloud & delivers messages to and from services running on the gateway device.
