Problems solved by technology

[0005] When the storage content of NOR FLASH or NAND FLASH is lost or changed due to accidental erasure or the storage medium itself, it will cause the boot program or system image to be changed or incomplete, and eventually the device cannot be started normally;
[0006] When the power supply of NOR FLASH or NAND FLASH is abnormal or the pins are loose due to mechanical collision, the boot program and system image program cannot be read, causing the device to fail to start normally;
[0007] When the power supply of NOR FLASH or NAND FLASH is too high and burnt, the boot program and system image program cannot be read, causing the device to fail to start normally.

Abstract

The invention provides a safe self-starting method and a system of a PowerPC backup system, belonging to the technical field of system reliability design. The method includes implanting a corresponding RCW, a boot program and a system image into at least two of a plurality of FLASH memories employed by a PowerPC, wherein one of the FLASH memories is stored as a default boot system and the other FLASH memories are stored as a backup system. The invention detects whether the main controller PowerPC is abnormal in loading RCW and loading bootstrap program and mirror image by an automatic detection device, automatically reconfigures the master PowerPC and reads the boot and mirroring programs from the backup boot program storage media when an RCW load or mirroring abnormality is detected. Through the method or the system, the device can work normally under the abnormal condition of the default startup process, and the reliability of the device is improved.

Description

Technical field [0001] The invention belongs to the technical field of system reliability design, and specifically relates to a safe self-starting method and system for a PowerPC backup system. Background technique [0002] The PowerPC main controller has a wide range of applications in various fields, covering the CPU market of servers and the embedded CPU market, in industrial control, network communication (such as SDN switches, high-tech optical routers, intelligent network adapters, etc.), medical / healthcare , Automotive electronics, consumer electronics (such as Nintendo home consoles, etc.), military industry is widely used. [0003] Existing devices with PowerPC as the main controller need to load the VxWorks or Linux system on the PowerPC main controller, and the boot program and system image of the operating system are stored on the storage medium NOR FLASH or NAND FLASH. When the device starts up, the main controller PowerPC reads the boot program and system image from ...
