Embodiment Construction

[0020] The technical solutions will be described in detail below with reference to the embodiments and the accompanying drawings.

[0021] like figure 1 and figure 2 As shown, the remote upgrade system of the PowerPC motherboard of the present invention, the PowerPC motherboard includes a PowerPC processor, a CPLD chip, an FPGA chip, an external interface, a network port chip and a Flash chip; wherein, the PowerPC processor connects the network port chip and the CPLD chip. , CPLD chip is connected to Flash chip and FPGA chip, FPGA chip is connected to set external interface, and the remote host is connected and logged in PowerPC processor through Ethernet.

[0022] The flash chip stores the boot program, operating system, application program and FPGA loader. Each program includes the main program file and the corresponding backup program file. The main program file is stored in the main program area, and the backup program file is stored in the backup area. And each main pr...

Abstract

Provided is a remote upgrade system and method of a PowerPC motherboard. A bootstrap program, an operation system, an application program and an FPGA loading program are stored in a Flash chip of the PowerPC motherboard. Each program comprises a main program document and a corresponding backup program document. Each main program document and each backup program document respectively correspond to independent check documents. After program documents are finished backing-up and transmitting, the local PowerPC motherboard is used for computing the check documents again and making comparisons between new check documents and old check documents prior to backup and transmission. If results agree, backup or transmission is finished; but if does not, old versions are reverted. The remote upgrade system and the method of the PowerPC motherboard have following beneficial effects: when the invention is utilized for update, no device cannot be started despite of document transmission and copy errors and damaged documents in a main program area caused by power failure and other accidents during an update process; and therefore remote reliable update is ultimately achieved.

Description

technical field [0001] The invention relates to the technical field of embedded device debugging, in particular to a remote upgrade system and method for a PowerPC motherboard. Background technique [0002] Embedded devices with PowerPC as the core processor have a wide range of applications in the fields of industry, communication, transportation and national defense, especially in some harsh working environments, PowerPC has been more favored by its high performance and high stability . [0003] As embedded product development cycles continue to shrink and customer needs change, shipped devices often require software upgrades to resolve issues. However, if each upgrade requires on-site operations, it will greatly increase maintenance costs and be time-consuming and labor-intensive. Therefore, designing a product that can be upgraded remotely will result in significant cost savings. However, although the advantages of remote upgrade are obvious, if there are unexpected s...
