Embodiment
Start the method for self-service upgrading and device unsuccessfully below in conjunction with the drawings and specific embodiments to a kind of network device firmware of the present invention to be described in detail.
Embodiment one
As shown in Figure 1, a kind of network device firmware starts the method for self-service upgrading unsuccessfully, comprises step:
After the described network equipment starts, the system indicator controlled on the described network equipment keeps normal bright state; Wherein, after the startup network equipment, initialization process can also be carried out to the described network equipment;
Completeness check is carried out to described firmware;
If by verification, then start described firmware, control the flicker of described system indicator, the described network equipment of normal startup simultaneously;
If not by verification, start TFTP (TrivialFileTransferProtocol, TFTP) server, monitor assigned ip address and port;
After main frame is by described assigned ip address and the new firmware of port transmission to the described network equipment, described tftp server is by new firmware write storage chip.
Specifically, after the described network equipment starts, first to load data into internal memory from the BOOTLOADER subregion of Flash memory chip and run, to complete the initialization to device hardware.After completing initialization, start to start firmware.In the process started, the integrality to described firmware, version etc. is needed to verify, if verify unsuccessfully, then make system indicator Chang Liang by GPIO register, start tftp server process simultaneously, monitor assigned ip address and port, wait for that main frame sends new firmware to the network equipment.
In addition, as shown in Figure 2, described method also comprises step:
Described network equipment electrifying startup, system indicator Chang Liang;
Connect between main frame and the described network equipment;
Described main frame by assigned ip address and the new firmware of port transmission to the network equipment;
Described firmware is verified, judges whether verification succeeds;
If success, by described firmware write falsh storage chip, system indicator glimmers, the described network equipment of normal startup;
If unsuccessful, return execution step and connect between main frame and the described network equipment.
Specifically, when system indicator normal bright time, illustrate that the guiding of firmware makes mistakes.Now, need to connect between the main frame with described IP address and the described network equipment, start TFTP client-side program, send new firmware to assigned ip address and port.Afterwards, from newly verifying this firmware, judging whether can verification succeeds.If energy, by described firmware write falsh storage chip, system indicator glimmers, the described network equipment of normal startup, otherwise, return execution step and re-establish connection between main frame and the described network equipment.
In the present embodiment, when after the failure of BOOTLOADER boot firmware, by GPIO mouth control system indicator light Chang Liang, then tftp server is started, monitor assigned ip address and port, wait for that client uploads new firmware, new firmware is re-write in FLASH storage chip to audit.Object of the present invention is exactly that when firmware starts unsuccessfully, BOOTLOADER directly starts the server of TFTP, monitors fixed ip address and port numbers in order to overcome the problem of the network equipment not with stitch and extra learning cost; Control a system semaphore by GPIO mouth simultaneously, make it keep Chang Liang, allow user know questions and prospect.User only to need computer, by netting twine interconnection network equipment (as router) arbitrarily network interface, to open TFTP client, can complete upgrading as this fixed ip address and the new firmware of port transmission.
Whether the present invention allows user understand by indicator light and goes wrong, and then carries out self-service firmware updating, does not need to carry out dismounting to hardware device itself, avoids the problem causing device damage.Specifically, the method in the present embodiment, install serial ports instrument additional without the need to taking equipment apart, user learning cost is less, independently can complete upgrading.
Embodiment two
Start the method for self-service upgrading unsuccessfully according to a kind of network device firmware of above-described embodiment proposition, the present embodiment proposes the device that a kind of network device firmware starts self-service upgrading unsuccessfully.
As shown in Figure 3, a kind of network device firmware starts the device of self-service upgrading unsuccessfully, comprising:
Initialization module, in order to carry out initialization process to the described network equipment;
Correction verification module, is connected with described initialization module, in order to carry out completeness check to described firmware;
Tftp server, is connected with described correction verification module, monitors assigned ip address and port and write in storage chip by new firmware after described firmware is not by completeness check;
Processing module, is connected with described tftp server with described correction verification module, in order to obtain the next new firmware of main frame transmission and to start this firmware;
Light control module, is connected with described initialization module respectively, in order to the often bright or flicker of control system indicator light; Described light control module is GPIO register.
Specifically, operationally, after the described network equipment starts, initialization module first to be utilized to complete initialization to device hardware, light control module control system indicator light Chang Liang.After completing initialization, correction verification module needs to verify the integrality, version etc. of described firmware, if verify unsuccessfully, then controls to make system indicator Chang Liang by light control module, starts tftp server simultaneously, monitor assigned ip address and port.When processing module obtains the next new firmware of main frame transmission, tftp server, by this firmware write storage chip, finally starts this firmware.If verification succeeds, then light control module control system indicator light flicker.
Wherein, as shown in Figure 4, described processing module comprises:
Firmware acquiring unit, is connected with described correction verification module and described tftp server respectively, in order to obtain the new firmware that main frame sends;
Start unit, is connected with described tftp server and described correction verification module respectively, in order to start firmware.
Specifically, after original firmware verifies unsuccessfully and connects between main frame and the described network equipment, firmware acquiring unit obtains the new firmware that main frame sends to the described network equipment.Correction verification module verifies new firmware, if verification succeeds, so tftp server unit is by this firmware write storage chip, and start unit starts new described firmware; Otherwise firmware acquiring unit obtains the new firmware that main frame sends again.When under correction verification module first time verification firmware just successful situation, remain start unit and start firmware.
It is worthy of note, described light control module is also connected with described start unit, and when new described firmware starts, described light control module controls the flicker of described Systematical control lamp.
For a person skilled in the art, after reading above-mentioned explanation, various changes and modifications undoubtedly will be apparent.Therefore, appending claims should regard the whole change and correction of containing true intention of the present invention and scope as.In Claims scope, the scope of any and all equivalences and content, all should think and still belong to the intent and scope of the invention.
