Description

A kind of many DSP intelligent nodes on-line software updating methods based on CAN
Technical field
The present invention relates to a kind of many DSP intelligent nodes on-line software updating methods based on CAN, the method can produced (JTAG mouthfuls and emulator cannot be used) under the integrated state of product and realize ONLINE RECOGNITION and the software upgrading of many DSP intelligent nodes, tool Have the advantages that operating method is simple, autgmentability is strong, security and stability is high, it is adaptable to standard CAN bus, DSP embedding assemblies Distributed measurement and control system based on machine.
Background technology
According to product development for many years and working service experience, distributed measurement and control system internal each insertion after product is integrated Formula intelligent node still has software modification higher and the upgrading frequency, and traditional approach is disassembled after product directly to each DSP intelligence Node is upgraded, or the JTAG emulation interfaces of DSP are drawn into product to realize software upgrading, and the above method is increasing workload While with time loss, certain influence can be also produced on product reliability；Cannot realize under system integration state, by one Bar STD bus realizes the software upgrading to specifying DSP in multi-DSP distribution type system.
Multi-DSP distribution type TT＆C system is specified in it cannot realize to system by a STD bus after product is integrated The software upgrading of DSP, it is necessary to product is disassembled after directly each node is individually upgraded, the method increase workload and when Between while consume, certain influence can be also produced on product reliability.
The content of the invention
The technical problem to be solved
In order to avoid the deficiencies in the prior art part, the present invention proposes that a kind of many DSP intelligent nodes based on CAN are soft Part online upgrading method.
Technical scheme
A kind of many DSP intelligent nodes on-line software updating methods based on CAN, it is characterised in that step is as follows：
Step 1：The programming mark of each DSP intelligent nodes is write in its in-chip FLASH particular address before product is integrated；
Step 2：The upper preceding XA14 pin configurations by all DSP intelligent nodes in product of electricity are low level after product is integrated, All DSP intelligent nodes are made to enter online programming pattern；
Step 3：It is connected to perform the host computer of online programming by the CAN interface outside product；
Step 4：Each DSP intelligent nodes identification XA14 pin configurations are soft to enter CAN passages after low level after electricity on product Part online upgrading pattern, the CAN interface demand required according to Bootloader using host computer online upgrading software is to each DSP intelligence Can node transmission bootstrap；
Step 5：Each DSP intelligent nodes receive bootstrap backed off after random Bootloader patterns, drawing in load operating RAM Helical pitch sequence, now host computer send intelligent node match information to each DSP intelligent nodes, DSP bootstrap is according to receiving Match information is matched with the programming mark in each DSP in-chip FLASHs particular address for reading, and the DSP that the match is successful enters Next step, remaining DSP exits the flow；
Step 6：Host computer receives after DSP sends the match is successful information and starts to send user program to slave computer, on Position machine to user program in every segment data carry out parsing transmission, the data segment larger for data volume carry out subpackage parsing and Interaction is sent to slave computer after location is redistributed, until the transmission of whole program is completed, the FLASH addresses that slave computer is received point With after requiring will on program Solidification to corresponding in-chip FLASH address, complete program burn writing after power off.
Beneficial effect
A kind of many DSP intelligent nodes on-line software updating methods based on CAN proposed by the present invention, the method is based on Bootloader guides the CAN on-line software updating method of system, by the autonomous match cognization pattern of multinode, realizes Identification and software programming are automatically selected to multiple DSP by a CAN；Meanwhile, realize the software liter of subpackage interaction Level pattern, breaks through limitation of original mode to software size.Reduce the work caused due to dismounting product in software upgrade process Measure and time loss, strong with autgmentability, operating method is simple, the advantages of security and stability is high, it is adaptable to all to can be used CAN carries out the DSP embedded computers of on-line software updating.
The features of the present invention：
1st, by the autonomous match cognization pattern of multinode realize by a CAN to the integrated state of product under it is many The identification and software upgrading of DSP intelligent nodes；
2nd, by the software upgrading pattern that upper and lower computer subpackage is interactive, DSP intelligent node CANs are breached To the limitation of software size under Bootloader modes；
3rd, after software upgrading is completed, all unmatched successful DSP intelligent nodes user softwares will not be modified, and protect The reliability of product is demonstrate,proved.
Brief description of the drawings
Fig. 1 is based on many DSP intelligent nodes on-line software updating method hardware interface figures of CAN
Fig. 2 is based on many DSP intelligent nodes on-line software updating method flow charts of CAN
Specific embodiment
In conjunction with embodiment, accompanying drawing, the invention will be further described：
, it is necessary to complete following three preparation before many intelligent node on-line software updatings of DSP are carried out：
A) the distinctive programming mark of each DSP intelligent nodes is write in its in-chip FLASH particular address before product is integrated；
B) the upper preceding XA14 pin configurations by all DSP intelligent nodes in product of electricity are low level after product is integrated, make institute There are DSP intelligent nodes to enter online programming pattern；
C) it is connected to perform the host computer of online programming by the CAN interface outside product.
The connection of its hardware is as shown in Figure 1.
After completing preparation, Software for Design is carried out as steps described below, flow chart is as shown in Figure 2：
(XA14 pin configurations are low electricity to the hardware state that each DSP intelligent nodes identification has been set after electricity on step one, product It is flat) enter CAN passage on-line software updating patterns, the CAN required according to Bootloader using host computer online upgrading software Interface requirements sends bootstrap to each DSP intelligent nodes；
Step 2, each DSP intelligent nodes complete the reception backed off after random Bootloader patterns of bootstrap, load operating Bootstrap in RAM, now host computer send intelligent node match information to each DSP intelligent nodes, DSP bootstrap according to The match information for receiving is matched with the programming mark in each DSP in-chip FLASHs particular address for reading, what the match is successful DSP enters next step on-line software updating flow, and remaining DSP exits the flow；
Step 3, host computer receive after DSP sends the match is successful information and start to send user program to slave computer, on Position machine to user program in every segment data carry out parsing transmission, the data segment larger for data volume carry out subpackage parsing and Interaction is sent to slave computer after location is redistributed, until the transmission of whole program is completed, the FLASH addresses that slave computer is received point With after requiring will on program Solidification to corresponding in-chip FLASH address, complete program burn writing after power off.
