Abstract
The present invention relates to a kind of cross-system serial ports upgrade method, include the following steps: that 1) host obtains the order of slave version number, determines download server upgrade file；2) host sends upgrade command, and slave returns to confirmation；3) host sends upgrading data packet, and slave receives and CRC check, executes updating operation.The present invention is easy to operate, reliability is higher when it is implemented, do not need gradually to be instructed, and is conducive to large area deployment upgrading Soc software.
Description
Technical field
The present invention relates to internet and Serial technology field more particularly to a kind of cross-system serial ports upgrade methods.
Background technique
Traditional platform of multiple operating systems, it usually needs USB and serial ports carry out local upgrade to slave system.Such upgrading
Mode not only needs to send upgrade file to client, or even needs to tear open machine connection serial ports.
Therefore, in specific operation process, all terminal users how to be contacted, how to distribute upgrade file, how into
Row updating operation requires to instruct one by one, and operation is very cumbersome, and reliability is lower, is unfavorable for large area deployment upgrading Soc
Software.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of cross-system serial ports upgrade methods, to solve in the prior art
Existing defect.
The technical scheme to solve the above technical problems is that
It is a kind of cross-platform based on multisystem, include the following steps:
1) host obtains the order of slave version number, determines download server upgrade file；
2) host sends upgrade command, and slave returns to confirmation；
3) host sends upgrading data packet, and slave receives and CRC check, executes updating operation；
Further, the step 1) specifically includes following several steps:
11) host side opens serial ports, obtains from generator terminal current software version number (now_version)；
12) host side requests network server, obtains from generator terminal recent software version number (new_version)；
13) work as new_version > now_version, host side downloads upgrade file；
Further, specific step is as follows for the step 2): host side sends serial ports upgrade command 0x15, makes from generator terminal
Response, returns to 0x18, and confirmation enters upgrade mode；
Further, specific step is as follows for the step 3):
31) host side receives 0x18, opens sub thread, circulation reads upgrade file, and transmits data according to struct
Packet, data are transmitted, and send 0x1a to from generator terminal, and prompt just in updating operation；
32) slave termination is carried out CRC check by 0x1a, and verification is errorless to execute upgrading, opens bootloader mode,
Flash erase/write storage region sends upgrading and completes to respond；
33) slave upgrading is completed, and returning response notice host side is restarted；
Further, the upgrade file is UPD file；
Further, it the host side and is communicated between generator terminal by UART protocol；
Further, the host side is Android system and supports the network port, is embedded OS from generator terminal.
The beneficial effects of the present invention are: the present invention is not when it is implemented, need gradually to be instructed, it is easy to operate, reliable
Property it is higher, be conducive to large area deployment upgrading Soc software.
Detailed description of the invention
Fig. 1 is packet structure of the present invention；
Fig. 2 is cross-system serial ports upgrade method timing diagram of the present invention；
Fig. 3 is cross-system serial ports upgrade procedure flow chart of the present invention；
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1-3, a kind of cross-system serial ports upgrade method, including
It is based on network programming and Serial Communication referring to Fig. 2-3 method of the invention, first request cloud and local soft
Part version compares and transmits upgrade file, and it is erasable finally to carry out FLASH.
When it is implemented, data structure is as shown in Figure 1, escalation process is as shown in Figures 2 and 3.
Data format illustrated in table 1:
Table 1
As shown in figure 3, host side is switched on first, auto checking network is simultaneously obtained cloud version number (new_version), main
Generator terminal opens UART, obtains from generator terminal current software version number (now_version).Work as new_version > now_version,
Host side downloading upgrading upd file.
Specifically, host side sends serial ports upgrade command 0x15, responded from generator terminal, return to 0x18, confirmation, which enters, to rise
Grade mode.
More specifically, host side receives 0x18, opens sub thread by Java Native Interface, circulation is read
It takes upd upgrade file, and data packet is transmitted according to struct, data are transmitted, and send 0x1a to from generator terminal, and prompt
Updating operation.
Finally, being 0x454B4F47 currently scalable equipment from generator terminal identification signature, identify msg for 0x19 upgrading
Categorical data carries out CRC check, and verification is errorless to execute upgrading.Slave upgrading is completed, and returning response notice host side is restarted.For
Convenient for the effect of observation upgrading, using Hi3798 as host side for illustrate.Hi3798 is exported by video, is shown to reply
Words frame prompt information: upgrade tip dialog box, file transmission prompting frame, upgrades successfully complete machine and restarts and mention downloading file prompting frame
Show frame, upgrading failed message etc..
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
