ABSTRACT:
A distributed nodal system with a source computer processor node storing program code for target node(s). A target node has an updatable firmware memory storing program code for operating a target processor. The target code comprises application code for controlling an embedded device, primary communication code for communicating with a network, backup communication code also having copy code for copying code between portions of the firmware memory, and primary boot code for booting the target processor and having check code. The check code determines whether the primary communication code is corrupted, and if it is corrupted, employs the copy code to overwrite the primary communication code with the backup code. If uncorrupted, the check code determines whether the application code is corrupted, and if corrupted, prevents execution of the code.
