Embodiment
As shown in Figure 1, the present embodiment is a kind of industrial camera that can the remote upgrade firmware, comprises fpga chip and processor that cameras work is controlled, and the configurator that stores FPGA needs external nonvolatile memory, namely flash; Also comprise Gigabit Ethernet controller and flash read-write controller in fpga chip.Flash comprises 32 sectors, wherein, and the 0-7 sector storage configurator that dispatches from the factory, 8-21 sector storage user program, the out of Memory of 22-31 sector storage camera.
In camera, processor CPU is the vitals of completing firmware upgrade in camera, it receives upgrade data from application program by Ethernet interface, then data are carried out verification, decoding, correct data are write FLASH by flash controller, and reply application program, reconfigure FPGA after upgrading is completed, the remote upgrade of final completion system.
Here, the FPGA remote system upgrade refers to by network or other data path, upgrade data be sent to system from developing the place, and then these data of system storage reconfigure the upgrading of FPGA device completion system with these data.FPGA remote system upgrade system mainly comprises three parts: flush bonding processor (CPU), Flash device, application program.Whole as follows:
Application program reads the upgrade file of FPGA, and form according to the rules sends to camera by Ethernet, and camera carries out verification to the data of receiving, if data are correct, data are write in FLASH, otherwise notification application resends data, guarantee to write data in FLASH accurately.
Adopt the FPGA of Altera in the present embodiment
In the product of Altera, according to the role of FPGA in whole layoutprocedure, can be divided into 3 classes: FPGA active mode (AS); FPGA passive mode (PS); The JTAG mode.
Under the AS configuration mode, by the FPGA on plate initiatively export control and synchronizing signal to a kind of series arrangement chip of Altera special use (as EPCS etc.), after configuring chip receives orders, just the configuring chip data are dealt into FPGA, complete layoutprocedure.Attention: this mode can only be used in conjunction with the active series arrangement chip that Altera provides (being EPCS series).
Under the PS configuration, initiate and control layoutprocedure by other equipment of system.These equipment comprise the configuring chip (EPC series) of Altera, or microcontroller (as single-chip microcomputer), CPLD etc.FPGA is in passive position fully, and just simple some status signals of output coordinate layoutprocedure.In the FPGA passive mode, comprise passive serial (PS), fast passive parallel (FPP), passive parallel synchronous (PPS), passive and line asynchronous (PPA) etc.Here the most frequently used, representative is the PS pattern, and this pattern is that all Altera FPGA support, general modal is to complete layoutprocedure with the configuring chip EPC series of Altera.When doing the PS configuration, the FPGA configuration data writes FPGA with data from inner the reading of storer (being generally EPC series) when the rising edge of clock arrives.
The JTAG pattern is the standard interface of IEEE 1149.1 boundary scan testings, is mainly used in the functions such as test of chip.Altera FPGA supports to be configured by the JTAG order mode of FPGA basically, and the configuration mode of JTAG is all more senior than other any configuration modes.
The above upgrades, and all needs from long-range, AKU correctly to be received, and therefore, the data that correctly receive AKU are exactly the key of the present embodiment product and method.
Concrete, FLASH is the parking space of the configurator of camera, and its capacity is 16Mb, altogether minute for 32 sectors, native system according to the actual requirements with its minute for three parts, be respectively used to deposit different data, concrete subregion is as shown in table 1:
The configuration of wherein dispatching from the factory is used for preserving the default configuration program when dispatching from the factory, and the user can not revise, and can be used for the emergent restoring system configuration when upgrading unsuccessfully.Final configurator is preserved in user's configuration, and the user can upgrade to system by long-range.Other message parts be used for to be preserved other information of product such as initialization and are arranged etc.
Table 1
As shown in Figure 3 and Figure 4, be the process flow diagram that carries out remote upgrade:
Comprise the steps: at industrial computer one end
A1, confirmation industrial camera to be upgraded withdraw from application program, enter the configuration code state of a control of dispatching from the factory;
A2, the packing of the firmware upgrade procedure of industrial camera is sent to respectively the step of industrial camera by gigabit Ethernet, in this step, packets need of every transmission is received the reply of the previous packet of correct reception that industrial camera is returned, otherwise, retransmit this packet, until all packets successfully send to industrial camera;
Carry out following steps at industrial camera one end;
B1, the guiding configuration code that dispatches from the factory, and send to industrial computer and enter the configuration code state of a control signal that dispatches from the factory;
B2, receive the packet of the firmware upgrade procedure that is sent by industrial computer, often receive a packet, whether correctly detect this packet, if correct, to the correct signal of industrial computer transmitting and receiving data bag, until correctly receive all packets;
B3, with in the flash that receives.
Packet as shown in Figure 2, application program and camera carry out exchanges data by Ethernet, adopt the 802.3/802.2 LLC frame format of standard, and be specific as follows:
Comprise the 802.2SNAP packet header of the 802.2LLC of the 802.3MAC packet header of 14 bytes, 3 bytes, 5 bytes, the data of 38～1492 bytes and the CRC check code of 4 bytes;
Due to the importance of configuration data, therefore must guarantee that makeing mistakes in transmitting procedure in time found and correct, so this system done extra verification to " data " part, " data " partly specifically form is as follows:
flag?+?type?+?legth?+?addr?+?data?+?sum
Wherein:
Flag indicates this bag and is the system configuration data AKU;
The particular type of Type unlabeled data AKU:
0x00--record description information;
0x01,0x02,0x03--the data of record storage, this three's difference are that the length of address (addr) is different, and 0x01 is 2byte, and 0x02 is 3byte, and 0x03 is 4byte;
0x07,0x08, the start address of 0x09--determine procedures;
This three's difference is that also the length of address (addr) is different, and 0x09 is 2byte, and 0x08 is 3byte, and 0x07 is 4byte;
