Abstract
A multiprocessor device includes a plurality of device subsystems each having a processor dependent on a respective other processor in another device subsystem for device operation. Each processor has at least one independent channel for updating a respective software version within the respective processor. A compatibility synchronization module has a database storing a table of compatible software versions for each processor. It is updated when a new software version for a processor is created. This table is independent of software images for the software versions. The compatibility synchronization module is operative for verifying if the software version for a processor is compatible with other software versions at other processors and instructs a respective device subsystem to revert back to a compatible software version within a respective processor or prevent any incompatible software updates within the processor.
