Abstract

A loading system and method for starting network devices are provided. An initialization module is for initializing the system environment and starting the auto-booting procedure. If the loading system receives an interrupt request, or if the loading system does not find any valid image, the loading system may suspend booting and enter an engineering mode.

The image verify module verifies the images, and transfers valid images to an image loading module.

Description

1254549 IX. Description of the Invention: [Technical Field] The present invention relates to a loading system and method, and more particularly to a system and method for activating a network device. [Prior Art] In the post-PC era of the rapid development of digital information technology and network technology, embedded systems have been widely used in various electronic devices. Usually, the load start task of an embedded system is completely done by the loader. Depending on the hardware design, the way to initialize the hardware will be different. The loader is a small program that runs before the operating system kernel (Kernel) runs. The hardware device is initialized by the load state to initialize the hardware device and create a map of the memory space, so that the operating system kernel is finally called. Most of the uranium's operations are divided into two parts, Phase 1 and Phase 2. Phase 1 is typically implemented in a combined language that includes: hardware device initialization, preparing RAM space for phase 2, setting up stacking, and jumping to phase 2 c entry point. Phase 2 is usually implemented in C language, including: initializing the hardware device to be used at this stage, detecting the system memory image (mem〇ry map), and mapping the kernel image and the root file system image from the flash memory. Read into the Rand〇m Access Memory (RAM) space, set the boot parameters for the kernel, and call the kernel. The operation of the existing loader is implemented in two phases, and the corresponding hardware devices are initialized at each stage, which reduces the efficiency of the system operation. In order to overcome the above drawbacks of the prior art, the present invention provides a loading system for configuring a network device, which optimizes a hardware initialization process and an implementation step of the embedded system, thereby speeding up network device startup loading. . In order to achieve the above object, the present invention activates a loading system of a network device, which mainly includes an initialization module, a trigger determination module, an image selection module, an image verification module, and an image loading module. , an engineering mode module and an electronic wipe 1254549 divide-only memory (Electrically Era sable Programmable

Read-Only Memory, EEPROM). The initialization module is used to initialize the system, the operating environment, and start the automatic boot program. The trigger determination module is used to determine whether the system receives an interrupt request from the user. The image selection module is used to read an image from an electronic eraser. The image verification module is used to verify that the image read by the system is valid. The image load module is used to load a valid image into synchronous dynamic memory (SDRAM). The engineering mode module provides a command line; on the I side, the user can input related commands to perform related operations, including maintenance of the flash file system (Fiash ROM file system), electronic erasing read only Afe, body, and through the XMODEM file. The transport agreement downloads a specific image. The implementation method of the loading system provided by the invention comprises the following steps: (丨) initializing the module after the system is started to establish a system running environment, and simultaneously starting the automatic booting program; (ii) the automatic booting program system guiding the system to enter the triggering mode to enter/ Engineering mode module; if the rider does not connect (four) side, enter the image selection module; (lii) if the image selection module is in the electronic owe, ίΐϊί successfully find the image, transfer the read image to the image verification guide Effectiveness, (1V) If the verification image fails, the interrupt automatically triggers the 'green right burst mode', successfully downloads the mosquitoes, and then right-clicks the program to return the specific image to the image verification group verification until the effect is valid. The 'image' and transfer it to the image manned module group to load a valid image. , home intrusion [implementation; step know fast network equipment manned start. r battle into the system 1〇〇 includes _initialization module 11〇, fly-image selection module 130, a map Taoshun group 120, .家.ka ugly group 140, an image loading module 丨 1254549 First, Cheng Mo Lai group 1_ and - electric reading in addition to light reading. The initialization module, and 110 is connected to the trigger determination module (10). The trigger determination module 120 is configured to receive an interrupt request of the H to determine whether to interrupt the automatic boot program. The image selection module 130 is configured to establish a connection with the electronic erasable read-only memory 170 and the image verification module 14 when the trigger determination module 120 does not receive any interrupt request, to erase the read-only memory from the electronic erasure. The image is read from the body 170 and transmitted to the image verification module 14. In the embodiment of the present invention, the image read from the electronically erasable read-only memory 17A includes an Auto-booting image, Diagn〇se Image and Runtime image. The operating system kernel (Kernel) of the network device is started from the guide. The diagnostic image is used to detect and diagnose the fSIC chip of the switch and the peripherals of the CPU. The running image is used to complete the main functions of the network device. Specific images are used to implement the special features of user-defined network devices. The image verification module 140 is configured to verify whether the image read by the image selection module 130 is valid. The image loading module 150 is used to load the image verification module 140 to verify a valid image. The engineering module 160 is used to trigger the determination module 120 to receive an interrupt request or the image verification module 140 to verify that the image is invalid, and provide the user with a command line interface 164 for the user to select to perform related operations. The picture of the younger brother is loaded into the software architecture diagram of the SiS 100.

The initialization module 110 is connected to the trigger determination module 120. If the user clicks the corresponding control button within 3 seconds after the loading system 100 is started or presses CTRL+C to issue an interrupt request, the trigger determination module 12 causes the fa/f automatic boot program according to the interrupt request issued by the user, thereby causing the loading. The system enters engineering mode.
