Description
Technical field
The present invention relates to data communication field and industrial control field, relate in particular to a kind of method and apparatus of updating firmware program.
Background technology
Firmware (Firmware) is the hardware with software function, this in early days hardware generally all is to have the EROM of software or EPROM (Electrically Erasable Read Only Memory) etc., usually the program of being preserved in these hardware can't directly be read or revise by the user, and the terminal user is difficult to or can not change firmware, also there is no need generally speaking firmware is carried out updating operation, also must change the EPROM on the original machine with the EPROM that finishes writing program by the professional even in firmware, found grave error (Bug).
Because the progress of integrated circuit at present, the firmware of equipment all adopts flash memory, and (Flash Memory is called for short: Flash) be carrier, and Flash supports the bootstrap loading routine function, most of Flash also support the upgrading of firmware simultaneously, therefore, it is more and more simpler that firmware updating also becomes, promptly when the environment of equipment changes or need add new function in equipment, can programme to the content of Flash and (or be called: programming), just carry out programming by the content to Flash again where necessary, and reach the purpose of firmware updating.
In order after dispatching from the factory, still to carry out software upgrading to equipment, so that equipment obtains the function of enhancing, perhaps in order to solve the Bug and the compatibility issue of some equipment by firmware updating, in equipment such as router, fire wall, Industry Control and system, extensively adopt Flash (to be called for short: Cun Chu medium firmware) as the firmware control program.When need be, when just needing again the firmware of burn writing equipment, adopt following several method usually to the firmware upgrade of equipment:
Method one, this method are for adopting JTAG (Joint Test Action Group, be a kind of international standard test protocol) etc. the method for upgraded in offline firmware of interface: the operate as normal that at first in the escalation process of firmware, needs halt device, by interfaces such as JTAG the content of Flash is carried out programming again and write new firmware then, perhaps change the well Flash of new firmware of programming, the last operate as normal of restorer again.
The shortcoming of this method is: at first firmware needs the operate as normal of interrupting device in escalation process, and needs operating personnel's execute-in-place and use special instrument in escalation process; Secondly, owing in Flash, only preserve a firmware program, when firmware must send Flash repair in shop multiple when upgrading is failed.
Method two, this method adopt the upgraded in offline method that starts boot control: at first the control program of equipment is divided into startup boot and primary control program two parts, after the equipment energising, starting boot at first moves, validity by detecting primary control program and need to judge whether the upgrading primary control program then, the primary control program of upgrading if desired, then communication interfaces such as serial ports by equipment or network interface are downloaded new firmware, and programming is in Flash.
The shortcoming of this method is: the operate as normal that needs halt device in the escalation process of firmware, simultaneously because the boot function is generally fairly simple, can't adopt the communication interface or the communication protocol of more complicated to obtain new firmware, so the range of application of this method also only limits to the local upgrade of equipment usually, and in escalation process, also need operating personnel's execute-in-place; Equally, in the method owing in Flash, only preserving a firmware program, when firmware must send Flash repair in shop multiple when upgrading is failed.
Method three, this method adopt the upgrade method of primary control program control: at first under the normal operating conditions of equipment, download new firmware and programming in Flash by the serial ports or the communication interface such as network interface of master control program by equipment, after equipment restarts, then load new firmware.
The advantage of this method is: communication interface and communication protocol support that the user can utilize primary control program to provide, and adopt the method for more complicated to download new firmware, reached the apparatus remote purpose of upgrading.
And the shortcoming of this method is: if equipment in escalation process because abnormal end, comprise cut off the electricity supply, network connectivity interrupts reasons such as (or can't line), servomechanism be out of service and causes the firmware upgrade failure, because it is old firmware that this abnormal end destroys the original firmware of equipment easily, thereby causes equipment to work normally.
Shortcoming at this method, can take corresponding improvement measures, promptly can be earlier new firmware downloads in the internal memory of equipment, just keep new and old firmware simultaneously, after finishing, new firmware downloads carries out the correctness checking procedure of new firmware, judge whether new firmware makes mistakes in downloading process, after the correctness verification succeeds of new firmware, again new firmware programming in Flash.The mistake that adopts this method effectively to avoid new firmware in transmission course, to produce, but to guarantee also that in the programming process of new firmware equipment can not power down, and must guarantee that new firmware can normally move after loading, otherwise still can cause the equipment can't operate as normal after upgrading, and can only adopt the method for other upgrade or repair that the firmware of equipment is recovered, make troubles for user's use.
In application scenarios such as unattended machine room, monitoring stations, when needs upgrade upgrading to equipment, in order to prevent the abnormal end in renewal process, promptly can't operate as normal for the equipment that prevents to cause because of abnormal end, even cause equipment must send factory's situation of programming firmware again, must assurance equipment reliable in escalation process.And above-described three kinds of methods all are difficult to thoroughly avoid causing because of the firmware upgrade failure fault of equipment.
