ABSTRACT:
A method of booting a multi-processor data processing device includes establishing a link between a first processor and a memory. The link is monitored to determine if, in response to a request from the processor, expected initialization data is communicated between the memory and the first processor. If unexpected data is detected on the link, the link is severed and a new link established between a second processor and the memory to allow the second processor to initiate the boot process. This ensures that, in the event of an error in the boot process at the first processor, the device can complete the boot process, thereby reducing device downtime.
