4. Software organization The ScanPall2 software system consists of three modules: • The Kernel module • The System (Operating System) module • The Program module Kernel Module The Kernel module forms the heart of the system. It is extremely secure and always protected by the system. Only a failure of the flash memory or incorrect switching off of the power supply, during system restart after a kernel update, can destroy the kernel.
For further information, refer to section 5.3.
Program Module The Program module operates on top of the System module. The user programs are downloaded into this module. The user program, downloaded into the Program module, is started automatically when the ScanPall2 is powered up. The user program pre-loaded into the Program module of the ScanPall2 is the application interpreter, making it possible to run an application created with the application generator.
