This method is after the loader utility upgrading is finished smoothly, also comprise a synchronous operation steps, see that the Loader that whether needs with new upgrading replaces original loader utility, this step is continued to be responsible for judging to main loader utility with from loader utility by the program of operation Loader, this deterministic process is controlled, carry out synchronous operation if desired, judge main loader utility with from loader utility consistent when guiding enters Loader next time, and then acquiescence is used main Loader operation.
This method specifically comprises the steps:
Step 11, start do not have upgrade information, directly jump to APP (application program from Booter (boot);
Step 12, start have upgrade information, but do not have E2PROM (EEPROM (Electrically Erasable Programmable Read Only Memo)), and perhaps Loader A and Loader B are destroyed, and directly jump to APP from Booter this moment;
Step 13, start detect the information of upgrading, upgrade by main loader utility or the effective Loader module from loader utility;
After step 21, the upgrading Loader success, need to judge whether synchronous operation, if need synchronous operation, then the Loader with new upgrading replaces original loader utility.
In the described step 21, when carrying out Loader synchronous operation, as power down in replacing old Loader process, cause old Loader destroyed, just upgrading realization Loader is synchronous once more after start next time, and two kinds of situations are arranged this moment:
If 1. next time, start did not have upgrade information, then leap to APP from Booter;
2. start next time to upgrading by former Loader module again, is jumped to Booter more then if upgrade information is arranged, and jumps to APP from Booter again.
The present invention has following advantage: take the storage mode of " syllogic double copies ", fundamentally improved the integrality and the security of upgrading, synchronizing process is fast and flexible.
[description of drawings]
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structured flowchart of the FLASH of the set-top box of use the inventive method.
Fig. 2 is the process flow diagram of the inventive method.
[embodiment]
See also shown in Figure 1ly, use the FLASH of the set-top box of the inventive method to be divided into two loader utility districts (Loader A program area and Loader B program area) and a Booter program area, a hardware parameter district, application area and other FLASH piece zone.
The syllogic double copies Loader upgrade method of set-top box of the present invention is in the Loader of set-top box FLASH A program area and Loader B program area is deposited main loader utility respectively and from loader utility, and deposits a Booter program in the Booter program area.This main loader utility and upgrade in turn from loader utility backups each other, and up-to-date module is used in the upgrading redirect, makes this main loader utility and can change each other from the role of loader utility two.Described Booter program is mainly used in initialization system, detects upgrade requirement information, main loader utility and from the integrality of the selectivity guiding of loader utility and this two loader utility of verification and master routine and to the judgement and the respective handling of accident failure; Loader partly is mainly the overall process of finishing upgrading with front end alternately, and the Loader major function of accepting guiding is that download, renewal and synchronous etc. process are finished in guiding.
This method is after the loader utility upgrading is finished smoothly, also comprise a synchronous operation steps, see that the Loader that whether needs with new upgrading replaces original loader utility, this step is continued to be responsible for judging to main loader utility with from loader utility by the program of operation Loader, this deterministic process is controlled, carry out synchronous operation if desired, judge main loader utility with from loader utility consistent when guiding enters Loader next time, and then acquiescence is used main Loader operation.
As shown in Figure 2, this method specifically comprises the steps:
Step 11, start do not have upgrade information, directly jump to APP from Booter;
Step 12, start have upgrade information, but do not have E2, and perhaps Loader A and Loader B are destroyed, and directly jump to APP from Booter this moment;
Step 13, start detect the information of upgrading, upgrade by main loader utility or the effective Loader module from loader utility;
After step 21, the upgrading Loader success, need to judge whether synchronous operation, if need synchronous operation, then the Loader with new upgrading replaces original loader utility.
In the described step 21, when carrying out Loader synchronous operation, as power down in replacing old Loader process, cause old Loader destroyed, just upgrading realization Loader is synchronous once more after start next time, and two kinds of situations are arranged this moment:
If 1. next time, start did not have upgrade information, then leap to APP from Booter;
2. start next time to upgrading by former Loader module again, is jumped to Booter more then if upgrade information is arranged, and jumps to APP from Booter again.
The concrete operations implementation procedure of the inventive method:
1, the long MENU key by set-top box of start ejects the upgrading picture, upgrades, and has upgraded and has jumped to Booter, jumps to APP from Booter again.
2, start is long by determining key, ejects input password prompt picture, can revise upgrade parameter after the success of input password, has revised the back and has upgraded by the MENU key, has upgraded and has jumped to Booter, jumps to APP from Booter again.
If the upgrading failure when parameter f orceupdate=0, turns back to input password prompt picture, when forceupdate=1, directly jump to APP from Booter.
3, start long by volume+/-, channel+/-on panel, show following information respectively behind the key, switch and can see by button.And then upgrade by the MENU key, upgraded second identical.
Volume+: show Loader version number
Volume-: the issuing time that shows APP
Channel+: show PID, Table ID, symbol rate, QAM pattern
Channel-: display frequency
4, APP issues the upgrade information of Booter, judges by the variable among the E2, when relevant variable set, upgrade information is arranged, and upgrades then.
5, start detects flash protection situation, judges by the variable among the E2, upgrades when relevant variable set.
