Abstract
The invention relates to a software upgrading method, in particular to a method for upgrading a programmable singlechip on a front panel of a set-top box. The invention provides a method for upgrading the programmable singlechip on the front panel of the set-top box, which is low in cost, convenient and rapid. The method mainly utilizes the communicating capacity between the singlechip on the front panel of the set-top box and a mainboard of the set-top box; firstly, upgraded software is copied on mobile storage equipment, then communication is realized through the mobile storage equipment and the mainboard of the set-top box; the communication between the mainboard of the set-top box and the programmable singlechip on the front panel is realized; finally, the upgraded software is imported to the programmable singlechip on the front panel to complete the upgrading function. The method for upgrading the programmable singlechip on the front panel of the set-top box saves manpower and physical resource, reduces production cost and is suitable for the upgrading of the programmable singlechips of the front panels of all the set-top boxes.
Description
Technical field
The present invention relates to method for upgrading software, specially refer to upgrade method set top box front panel programmable SCM.
Background technology
Continuous development along with Digital Television, the integrated level of the components and parts on the digital TV products is more and more higher, function also from strength to strength, major part all is the paster components and parts, the shared proportion of components and parts wherein able to programme is very big, and this embodies the most obviously in digital TV set-top box, and the single-chip microcomputer of a control front panel display is arranged on the front panel of set-top box usually, this single-chip microcomputer is again and the main components and parts of mainboard communication and control front panel display simultaneously, and it is programmable.Because the difference of set-top box scenario, requirement to this software is also different, just need us very easily its software to be upgraded and safeguard, and usual way is by programmable device software to be write single-chip microcomputer earlier, assemble behind the paster then,, just must take off single-chip microcomputer and write journey by programmable device again if Single Chip Microcomputer (SCM) program goes wrong or needs update software, so just bring man power and material's consumption, improved cost.
Summary of the invention
At the method labor intensive of above-mentioned prior art and the deficiency of material resources, technical matters to be solved by this invention is: a kind of low cost, the method for upgrading set top box front panel programmable SCM conveniently are provided.
The technical scheme that the present invention solves the problems of the technologies described above employing is: the method for upgrading set top box front panel programmable SCM, and it may further comprise the steps:
A. upgrade software is copied on the movable storage device;
B. connect movable storage device and set-top box mainboard;
C. the set-top box mainboard recognizes movable storage device, and reads the upgrade software that is stored in the inside;
F. the set-top box mainboard is encoded to upgrade software, and carries out communication with front panel programmable SCM;
G. front panel programmable SCM receives data and verification and decoding, writes its storer afterwards.
Further have, after execution in step c, follow execution in step:
D. the version of set-top box mainboard comparison upgrade software and the existing software program of front panel programmable SCM more just continues execution in step e as if the former, otherwise shut-down operation;
E. the set-top box main board system is judged the current state of front panel programmable SCM, if the free time just sends data, otherwise just waits for.
The invention has the beneficial effects as follows: saved manpower and materials, reduced production cost.
Description of drawings
Fig. 1 is a scm software upgrading FB(flow block) in the embodiment of the invention.
Embodiment
The invention provides a kind of low cost, the method for upgrading set top box front panel scm software conveniently, the programmability that its cardinal principle has been to use ability to communicate between single-chip microcomputer and the mainboard and single-chip microcomputer itself to possess, by the data transmission interface on the mainboard, utilize the mainboard program that the Single Chip Microcomputer (SCM) program that the needs on the data source upgrade is imported, thereby carry out software upgrading.
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the method for the upgrading set top box front panel programmable SCM in this example mainly utilizes ability to communicate between USB movable storage device, set-top box mainboard and the front panel programmable SCM to realize the software upgrading of single-chip microcomputer.
This method may further comprise the steps:
A. upgrade software is copied on the USB movable storage device;
B. connect USB movable storage device and set-top box mainboard;
C. set-top box mainboard procedure identification arrives the USB movable storage device, and reads the refresh routine that is stored in the inside;
D. the version of set-top box mainboard program comparison refresh routine and the existing program of front panel programmable SCM if the former is newly with regard to execution in step e, otherwise is cancelled operation;
E. the set-top box main board system is judged the state of current front panel programmable SCM, if the free time just sends data, otherwise just waits for;
F. set-top box mainboard program is encoded to said procedure, and carries out communication with front panel programmable SCM;
G. front panel programmable SCM receives data and verification and decoding, writes its storer afterwards.
On concrete enforcement, can adopt host-host protocol such as IIC, the GPIO etc. of standard between set top box front panel and its mainboard.The set-top box mainboard is encoded to it after reading refresh routine, the coding here is that the software that needs upgrade is carried out piecemeal on request, be transferred to front panel programmable SCM then, finish by front panel programmable SCM again the data that receive are carried out verification, upgrade software is write single-chip microcomputer upgrade.
Claims (2)
1. the method for upgrading set top box front panel programmable SCM, it is characterized in that: it may further comprise the steps:
A. upgrade software is copied on the movable storage device;
B. connect movable storage device and set-top box mainboard;
C. the set-top box mainboard recognizes movable storage device, and reads the upgrade software that is stored in the inside;
F. the set-top box mainboard is encoded to upgrade software, and carries out communication with front panel programmable SCM;
G. front panel programmable SCM receives data and verification and decoding, writes its storer afterwards.
2. the method for upgrading set top box front panel programmable SCM as claimed in claim 1 is characterized in that: then execution in step after execution in step c:
D. the version of set-top box mainboard comparison upgrade software and the existing software program of front panel programmable SCM more just continues execution in step e as if the former, otherwise shut-down operation;
