The invention can be used in the TV with USB module with online program and TV upgrade recognition functions. Compared with present technique, it inserts the external memory with upgrade software and USB interface into interface of TV; the main body CPU and CPU of USB module can automatically refresh the former program, without additional device and opening device.
Description
Technical field
The present invention relates to television set, especially relate to a kind of upgrade method of TV set software.
Background technology
The upgrade method of existing television set (hereinafter to be referred as TV) software mainly contains two kinds.A kind of is the bonnet of dismounting TV, directly changes the program of the CPU (hereinafter to be referred as TV-CPU) of TV mainboard, needs the field service department door to adopt professional equipment just can finish, and its step is very loaded down with trivial details, the cost lot of manpower and material resources; Another kind is the upgrade port that is provided with by at TV, upgrades with computer is online, and the user who has only configuration computer and be familiar with computation could adopt.In addition, existing most digital TV will comprise the functional part of the USB module of USB interface as standard configuration, be provided with in the described USB module usb bus is converted into USB interface that the parallel port bus uses for processor, will plays and export to CPU (hereinafter to be referred as USB-CPU) that the TV mainboard shows from multi-medium data (MPEG, the JPEG) decoding that USB interface reads, cooperates the SDRAM as its deal with data buffer memory use with USB-CPU, and the FLASH of preservation USB-CPU software program.Configuration USB module is mainly used in external memory device carries out exchanges data, and not seeing as yet so far has the software upgrade method of carrying out the TV mainboard by USB interface simply and easily.
Summary of the invention
Technical problem to be solved by this invention is, overcomes above-mentioned the deficiencies in the prior art, proposes a kind of upgrade method of utilizing the TV set software of USB interface, and the after-sale service of carrying out TV software upgrading and manufacturer for domestic consumer brings convenience and benefit.
Technical problem of the present invention is solved by following technical scheme:
The characteristics of the upgrade method of this TV set software are: following steps are arranged successively:
(1) whether the detection of stored medium are correct TV upgrade softwares:
Medium is inserted on the USB interface of TV configuration, judges by the USB-CPU detection of upgrade software function whether the software in the medium is correct TV upgrade software, if not, just withdraws from the software upgrading pattern, enters normal mode of operation with identification TV; If USB-CPU just reads in correct TV upgrade file among the SDRAM and preserves, and enters the TV-CPU ROMPaq of step (2);
(2) make TV-CPU enter the ISP mode state:
USB-CPU passes through the RS232 bus earlier and sends order to TV-CPU, it is entered start the section program, makes TV-CPU enter the ISP mode state, and turns off all interruptions, stops the program of current operation, waits for receiving data;
(3) FLASH is gone in correct TV upgrade file programming:
Begin to wipe common section program among the TV-CPU, wipe finish after, send order to USB-CPU, make it that step (1) is preserved correct TV upgrade file and send to TV-CPU, it is gone into common section original among the program storage FLASH of oneself program from programming by TV-CPU by the RS232 bus;
(4) soft start TV-CPU carries out the TV upgrade file:
After programming finishes,, restart to carry out the TV upgrade file, utilize the process of USB interface upgrading TV software so far to finish from common section program by the startup section program soft start TV-CPU among the TV-CPU.
Technical problem of the present invention is solved by following further technical scheme:
Described television set is to dispose the television set that the CPU in USB module and the USB module has online programming (in-system-programming is called for short ISP) and identification TV upgrade software function.
CPU in the described USB module is connected by the CPU of RS232 interface with the TV mainboard.
Described correct TV upgrade software is, the bin that specifies name or hex form arranged and be provided with the software of the identification code of correct sequence numbering form at its leading portion or back segment, and is chaotic and cause the upgrading failure to prevent with other software.
The basis for estimation of described correct TV upgrade software is, behind the software of USB-CPU in reading medium, take out wherein identification code and with program own in the identification code reserved in advance whether in full accordly compare.
Startup section program among the described TV-CPU is provided with start-up code, is final stage in the software.Be used under the ISP pattern, reading the programming data, and go among the program storage FLASH of oneself from programming.Read common section program running owing to carry out the normal play operation, read the start-up routine operation and carry out the ISP operation, at first be that CPU enters the ISP pattern, the program of ordinary procedure section is wiped, receive the outside routine data of sending here by cooperating again, and be written to original ordinary procedure section, write the back that finishes CPU is carried out soft start with RAM, restart to carry out the program of ordinary procedure section, like this ISP wipe with ablation process in can not make a mistake.
The inventive method is applicable to that the CPU that disposes in USB module and the USB module has the television set of online programming and identification TV upgrade software function.The beneficial effect that is compared with the prior art is: the external memory that will be loaded with the band USB interface of upgrade software, the corresponding interface as USB flash disk or portable hard drive insertion television set, the mainboard CPU and the CPU in the USB module of television set can refresh the original system program automatically under the control of program, whole process does not need the auxiliary of other equipment, do not need to turn on television set yet, convenient simple and direct, thoroughly solved the problem that TV ROMPaq in the past is loaded down with trivial details and need extras, the after-sale service of carrying out TV software upgrading and manufacturer for domestic consumer brings convenience and benefit.
Embodiment
A kind of upgrade method of digital TV software
The CPU that numeral TV disposes in USB module and the USB module has ISP and identification TV upgrade software function.Be provided with in the USB module that is disposed usb bus is converted into USB interface that the parallel port bus uses for processor, will plays and export to USB-CPU that the TV mainboard shows from the multi-medium data decoding that USB interface reads, cooperates the SDRAM as its deal with data buffer memory use with USB-CPU, and the FLASH of preservation USB-CPU software program.USB-CPU wherein is connected with TV-CPU by the RS232 interface.
The upgrade software of numeral TV is bin formatted file one 42L98_update.bin of 42L98_update for specifying name, and manufacturer is provided with the identification code of correct sequence numbering form at leading portion of this document or back segment.
The upgrade method of numeral TV software has following steps successively:
