Abstract

The embodiment of the invention provides a bootstrap program updating method and data processing equipment, and the method comprises the steps that in response to the fact that SPIs of a first device, a second device, a first memory and a second memory are all connected to a CPLD, the data processing equipment is powered on and started. Wherein a bootstrap program of the first device is stored in the first memory, and a bootstrap program of the second device is stored in the second memory; in response to the situation that the boot program stored in the first memory is abnormal, the first device is suspended and the second device is successfully started, and according to the first update mapping information in the CPLD, establishing a corresponding relationship between the second device and the first memory; the second device updates the new boot program into the first memory. Through the technical scheme of the embodiment of the invention, the problem that time and labor are wasted as the memory with the abnormal bootstrap program needs to be taken down for re-burning after power failure in the prior art is avoided, and the time and the labor cost are saved.

Description

technical field [0001] The disclosed technical solution relates to the technical field of the Internet, in particular to a method for updating a boot program and a data processing device. Background technique [0002] In the Internet era, data sending and receiving, traffic exchange, data processing and other links are indispensable. In these links, data processing equipment occupies a crucial position. With the increasing demand for information exchange and the rapid development of the Internet, the speed and magnitude of data traffic exchange are increasing day by day. A CPU (Central Processing Unit, central processing unit) system data processing equipment is facing this large-scale, High-speed traffic processing is becoming more and more stretched, so multi-CPU system data processing equipment emerges as the times require. [0003] In the existing multi-CPU system design, the memory installed with the boot program is directly connected to the SPI (Serial Peripheral Int...
