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. The Kernel module guarantees that the user can always
download his program, even when the operating system has been damaged by
the user program.
The Kernel module allows the following operations to be performed:
• Program Download
• Update Kernel
• Test & Calibrate
• Version
For further information, refer to section 5.4.

be performed:
