Embodiment
below in conjunction with accompanying drawing, the present invention will be further described: as shown in Figure 1,a kind of control remote software upgrade-system of video monitoring system, be comprised of digital signal processor TMS320F28335, the miniature toggle switch of four-way, FPGA programmable logic device (PLD) XC3S400, ethernet communication chips W 5300 and FLASH storer S29AL008J; It is characterized in that: external communication interface is Ethernet interface, by the instruction of Ethernet interface receiving remote and data and return to related data or state; Data line, address wire, read-write, chip selection signal, the look-at-me that digital signal processor TMS320F28335 connects is connected respectively on the FPGA programmable logic device and on the FLASH storer, by other peripheral components of decoded operation of FPGA programmable logic device; One end of each passage of the miniature toggle switch of four-way is GPIO84, GPIO85, GPIO86, the GPIO87 pin of linking number word signal processor TMS320F28335 respectively, and an other end connects 10 ohm pull down resistance to earth signal.
Described data line is 16 position datawire XD15～XD0; Address wire is low 12 bit address line XA11～XA0; Read signal is XRD, and write signal is XWR; Chip selection signal is XZCS0, XZCS6, XZCS7; Look-at-me is used TMS320F28335 external interrupt 1; For outside FLASH storer Starting mode, need to revise CMD configuration file and the design assembly code relevant to startup in TMS320F28335 software.
Second and third channel during described four-way toggle switch connects is allocated to the connection pull down resistor makes the start-up mode pin of digital signal processor TMS320F28335 be respectively GPIO84 high level, GPIO85 low level, GPIO86 low level, GPIO87 high level, is about to digital signal processor and is set to outside XINTF16 position start-up mode; Under this pattern, after the digital signal processor electrifying startup, can automatically jump to outside addressing space executive routine code.
As shown in Figure 2, the startup flow process of video monitoring system dsp controller software is: after electrification reset, the controller start-up routine is according to the Determines start-up mode of specific four the IO mouths in outside (GPIO84, GPIO85, GPIO86, GPIO87), design circuit is pulled to the 3.3V high level by GPIO84 and GPIO87, and GPIO85 and GPIO86 are pulled down to the 0V low level.Under this pattern, program can jump to the first place in the ZONE6 district that is positioned at address 0x100000 and put.After redirect, execution is forbidden to house dog, program redirect and program move code.Code is moved to internal RAM, and program code is carried out.
Redirect assembly routine design after the startup of described digital signal processor TMS320F28335 software; at first this program judges whether the house dog register enables after starting; close the register protection if do not enable; make register addressable and arrange and to forbid the house dog operation, and jump to code and move program address.First place in the ZONE6 district is put and jumped to assembly code and the house dog that house dog forbids and forbid that code is added in the DSP2833x_CodeStartBranch.asm file and adds in engineering.
The code of described digital signal processor TMS320F28335 software is moved the assembly routine design, the entrance of this program need to be inputted three variate-values, respectively that start address, operational objective start address and code length are moved in guiding, three variablees are inputted when .CMD file .text section arranges boot parameter, when operation, program is carried out Code copying according to these three parameters, and the code of outside FLASH storer is moved to internal RAM.Program code is moved to assembly routine to be added in the DSP28xxx_SectionCopy_nonBIOS.asm file and to add in engineering; The CMD configuration file is modified according to outside FLASH start-up mode, and the ZONE6 district is pointed in the program segment position.After each dsp controller starts, all code can be moved in internal RAM and moved.While needing remote upgrade, to the write operation of outside FLASH storer, can not affect the operation of program.Use CCS programming tool composing software engineering, obtain .OUT and .MAP output file.
The .OUT file destination generated after described digital signal processor TMS320F28335 software translating need to convert the .HEX file to, could pass through the code data in the communication interface Transmit message.Crossover tool is HEX2000.EXE, and CMD command file and the HEX2000.EXE instrument that need to write input/output format call the .BAT file; This document has defined input file title and output file title, and input file is .OUT file and the .MAP file after compiling, and output file is .HEX; The CMD command file has defined the output file bit wide, because digital signal processor instructions is 16, so be defined as 16 bit wide forms of output here; .BAT document definition HEX2000.EXE format conversion instrument and CMD command file title; Above file is placed on to same path, double-clicks the .BAT file and can complete conversion, obtain final ROMPaq code file.
As shown in Figure 3, the operating process of carrying out remote upgrade need be when digital signal processor works: digital signal processor and circuit thereof power on after operation, and operation host computer code transmits software, selects to need the .HEX file sent, and clicks and sends; Code transmits software and sends the upgrading order according to communication protocol by ethernet interface, digital signal processor sends instruction to FPGA according to order request, ZONE7 sheet choosing connection FLASH memory chip is selected to enter into upgrade status and return be ready to status code, now the FLASH storer is as the data field addressing space of digital signal processing; The host computer code transmits after software is received status code the HEX format code is sent to digital signal processor, and digital signal processor is kept in the data that receive in the RAM data field; The host computer code transmits software and sends the complete instruction of upgrading, digital signal processor will be temporarily stored in data programming in RAM in outside FLASH storer and return and upgrade successfully status code, restart digital signal processor, the program of new upgrading is moved to internal RAM and is moved.
