Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] System embodiment

[0028] In this embodiment, a system for starting a single board is provided, and the single board includes a CPU and a program memory.

[0029] Such as figure 2 As shown, the single board startup system according to this embodiment includes: a first BOOT202, connected to the single board through a chip socket, for starting the CPU; a second BOOT204, located in the program memory, storing version information for starting the CPU and a switch control module 206 for starting the CPU with the first BOOT202 or the second BOOT204 as the master BOOT failing to start the CPU, using the other one of the first BOOT202 and the second boot guide core 204 as the slave BOOT to start the CPU.

[0030] It should be noted that not only the version information of the second BOOT 204 is stored in the program memory, but...

Abstract

The invention provides a single-plate startup system, which comprises a first startup booting chip which is connected with a single plate by a chip socket and used for CPU startup; a second startup booting chip which is arranged on a program storage, stores version information of the first startup booting chip and is used for starting a CPU with the version information; and a switch control module which is used for taking the other one from the first startup booting chip and the second startup booting chip as the secondary startup booting chip to start the CPU under the situation that CPU startup of the main startup booting chip which is the first startup booting chip or the second startup booting chip fails. The invention further discloses a single-plate startup method. The single-plate startup system and the single-plate startup method can flexibly realize version update and maintenance of the main and secondary BOOT after the CPU runs normally, thus lowering version update risks and improving system startup reliability; furthermore, the single-plate startup system and the single-plate startup method have simple implementation, and do not need additional devices, thus lowering system cost.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a single-board startup system and method. Background technique [0002] At present, most system boards have small CPU systems. Usually, a small CPU system includes CPU processor, RAM (memory), boot boot chip (BOOT), program memory (FLASH), erasable programmable logic device (EPLD) and other devices. The CPU is the brain of the single board, and BOOT It is responsible for guiding the CPU system to start. The software version running by the CPU is stored in the FLASH. The EPLD acts as address decoding, chip selection allocation, and cooperates with the realization of watchdog functions. Usually, the system single-board CPU small system structure is as follows: figure 1 shown. When the board is powered on, the chip selection CSO takes effect, and the CPU starts under the guidance of BOOT. After the startup is successful, the chip selection CS1 takes effect. The softw...
