SYSTEM AND METHOD FOR REPROGRAMMING NODES IN AN AUTOMOTIVE SWITCH FABRIC NETWORK

摘要

A system and method for reprogramming nodes in an automotive switch fabric network using a diagnostic interface. The switch fabric network includes a plurality of nodes joined by communication links for the transmission of data there between. The plurality of nodes includes at least one target node. The target node includes a processor, a transceiver, and a memory. The memory includes an erasable memory portion and a protected memory portion. The processor in the target node switches from executing instructions in the erasable memory portion to executing instructions in the protected memory portion during a reprogramming period when the target node erases a current software component and stores a new software component in its erasable memory portion. The diagnostic interface is adapted to transmit the new software component to the target node.
