Embodiment
The invention provides a kind of base station single-board bootstrap program module method for down loading, as shown in Figure 2, comprising based on microcontroller:
Below method provided by the invention is elaborated.
If use unified BOOT to download: when backstage transmission download enables, the download enable module of plate supporting module (BSP) is called by operation maintenance center (OMC), download enables in the process, the RST reset signal and with download enable signal and bind together, this binding signal of the logical process of hardware, in Reset Board, sent the order that download enables to veneer.After the download enable signal issued, MCU entered BOOT immediately after logical process is downloaded enable signal.Such processing makes unified BOOT accomplish that in process of downloading version and downloading process have nothing to do.
After BOOT powered on, at first register was downloaded in interpretation, judges whether and can download, if can not download, resets, and returns application program; Otherwise the board software that enters BOOT is downloaded flow process.Utilize download to enable MCU and enter the download flow process, can avoid the intervention of the junk data on the link like this, guarantee that simultaneously the download module of hardware is effective before download.
MCU is in entering the download flow process of BOOT, and the reception of pending datas such as (as less than 9s) in effective time if can't receive data in effective time, represents that the data of OMC do not send over, and automatically resets, and turns back to the version application program; If version exists, then move original version program, otherwise WTD is overtime to be resetted, and continues to enter BOOT, wait for gathering data arrival, up in the limited time, receiving data, could begin the mutual of data, concrete flow process is as shown in Figure 1.
The veneer of downloading belongs to Radio Frequency Subsystem RFS and baseband subsystems BDS respectively, SAM, BTM, RIM, GCM belong to baseband subsystems, RFE, PIM, LPA, DPA belong to Radio Frequency Subsystem, the download management module of Radio Frequency Subsystem is on RMM, the baseband subsystems download management module is on CCM, both download path differences are so need a sign to be distinguished.Therefore need a pair of handshake information between MCU and the OMC, to determine that veneer still is the BDS frame at RFS.
Under the situation that makes the continuous dilatation of base station sub-system (BTS), it is stable that BOOT still keeps, and just need avoid frame and avoid physical label, accomplishes the mutual physics independence of certain master control borad of BOOT and OMC, i.e. hardware independent.In order to reach this purpose, the backstage at first sends the version download request to the BOOT of MCU, and MCU intercepting the other side's process module No. is as purpose process module.Because each veneer is according to actual conditions, the veneer running environment difference of design, thereby confirm whether can't to accomplish the BOOT unification of all veneers with veneer running environment with which process module communication, veneer running environment such as SAM is RFS frame and BDS frame, in different running environment, its communication modes is inconsistent, communicate by letter with CCM and to adopt point-to-point mode, the employing bus mode of communicating by letter with RMM, and the veneer running environment of PMM only is the PWS frame at present, specifically be connected with which running environment such as RFS frame, still be connected with the BDS frame, PMM can't know.Some veneer is in different running environment, its communication modes is different, in order to make veneer under different running environment, effectively carry out correct communicating by letter with the process module on backstage, thereby need unify communication mode according to running environment, simultaneously in order to help after the expansion of communication mode in future, the BOOT of all veneers still can unify, and regulation is utilized 485 mode of operations, communication mode with definite veneer is the bus communication mode, still point-to-point communication mode.Above process can make BOOT process module corresponding with the veneer current environment under different running environment of all veneers communicate with the communication pattern that requires, and do not consider the design feature of veneer and the physical label of veneer running environment, thereby the BOOT that makes all veneers reaches unified, makes BOOT keep stable under the situation of hardware dilatation.
In fact, no matter carry out alternately, all be to carry out alternately with the process module of master control borad with which master control borad, a veneer can carry out with n process module alternately.As long as we change the identification that collimation mark is known into to the communication program module identification, just can be implemented in the stability that keeps BOOT under the situation of hardware dilatation.
In order to discern the other side's process module, BOOT need send to OMC and send out broadcast.After BOOT download OMC transmission is downloaded and is enabled, enable effectively when detecting to download, send broadcast to OMC, promptly send to download to the process module of the communication master control borad of current BTS frame all working and enable effective message, which process module is received message, and which process module is just responded, BOOT need not to know that what master control borad the other side is like this, on what framework, only need on link, separate the process module No., carry out just passable alternately with the process module of replying message.Containing information in the packet that BOOT receives comprises: originating process, purpose process, source address, destination address, message number, message-length, message content etc., the download reality of so-called OMC and foreground veneer singly be between two processes carrying out alternately, BOOT is when intercepting the other side message like this, the fixed data structure of message that need be by communication protocol regulation is obtained the other side's originating process number, is exactly that BOOT need send the purpose process number of message.
So just accomplish the hardware independence that BOOT and master control borad are mutual, at hardware changes such as machine frame dilatation in the future, BOOT can both guarantee stability.
Because the implication of the board type of hardware definition is a radio type, a veneer can have a plurality of board types; And the board type of software definition, type of a veneer; For veneer is discerned and verification, avoid the data interaction failure of veneer and master control borad, adopt module group differentiation veneer, the agency directly sends to veneer to the module type of veneer by the OMC foreground, the BOOT of veneer separates the module type loopback from link and gives the OMC foreground, the different veneer of BOOT identification is correspondingly processed, as this plate address process, mix the communication process of frame veneer, also realize the different requirements to baud rate of different veneers simultaneously.
In the downloading process, the data interaction of BOOT comprises the data interaction of debugging mode and the data interaction of operational mode.
If it is debugging mode that BOOT detects current pattern, data interaction is carried out by serial ports in the debugging backstage of BOOT and PC, serial ports is supported serial ports and the outer serial ports of Uart550 sheet in the Uart232 sheet, no matter the download of debugging mode is at serial ports in the sheet or the outer serial ports of sheet, it all is point-to-point communication mode, do not need to carry out the address and judge, be used in the BOOT debugging of Single plate for load engaging and use the debugging backstage to carry out software download.
If it is operational mode that BOOT detects current pattern, if be point-to-point communication pattern, judge with regard to not carrying out the address, carry out alternately with the downloading process module that resides in CCM of BDS;
If be the bus communication mode, just need carry out the address and judge hanging on the bus veneer, the veneer of BTS bus communication is respectively at LPA frame, TRX and RFE frame, the SAM of TRX frame and BTM repeat with the 0 groove position and the 1 groove position of RFE frame on the address, the matching design of hardware logic is to add 8 to handle on the address of TRX frame, avoids the address misjudgment.When bus data received, if reception selection address is consistent with this plate address or reception selection address is a broadcast address, then the RMM logic was this plate address for transmission selection address, sends to this plate for the RMM data are described, then carries out Data Receiving.The transmission of veneer data needs the application bus, and current transmission selects the address consistent with this plate address, and then RMM logic reception selection address is this plate address, this plate obtains bus, finish when current 550 data that send buffering area send, bus has been treated on the buffer data in time-delay, discharges bus.
The backstage at first sends the version download request to the BOOT of MCU, the collimation mark that contains RFS and BDS is known, the BOOT of MCU separates the process module No. of OMS foreground process module after receiving the software download request message, respond the message that the software download request is responded according to the process module No. to the OMS foreground.
BOOT carries out verification to download request order (message), errorless after, respond version download request order (message) and reply.
OMC foreground agency sends the version download request to BOOT, and the download request order is that the backstage determines whether to possess the condition of download by the response on foreground, if possess, the backstage sends the version download request and carries out the download of edition data.BOOT is obtaining the process module No. that OMC foreground agency is possessed, and after verification passes through, responds the version download request to mutual process module and reply.
When BOOT receives the message of the version download of acting on behalf of the process module that resides in master control borad in the OMC foreground, just enter formal data and downloaded interaction flow, BOOT carries out verification to the 1st frame data that OMC foreground agency downloads, verification comprises the message number verification, the frame number verification, quiet lotus length check, the Flash read-write check, if check errors, respond the corresponding check errors of current download frame to OMC foreground download agent, the OMC foreground agency retransmit at erroneous frame, if send 5～10 frames, still mistake, OMC just thinks the download link problem, ends to download flow process, failed download; Otherwise BOOT writes Flash to present frame, continues to download the next frame edition data.
So MCU BOOT and OMC one frame one frame ground go down alternately.
Receive the sign of the last frame that the backstage sends as the BOOT of MCU after, promptly frame number is FFFE, responds the sign of last frame to the backstage, and promptly frame number is FFFF, and the message of software download success is sent in the backstage after receiving this sign.So far, whole download flow process is finished.
