and step S203, starting the advanced security system, and writing the identification of the advanced security system to the advanced security zone bit area.
According to the technical scheme, the flash is written once, then the non-high-security boot is started, high-security opening is achieved in the starting process, and meanwhile, only the high-security boot is moved. Since the boot is small, the entire transfer process takes only a few seconds. Thus the time to produce a high security set top box can be reduced to 1 to 2 minutes (including production testing).

In an alternative arrangement, the first and second electrodes may be,
if the advanced security zone bit area has no advanced security system identification, determining that the advanced security system is not started;
and if the high-level safety zone bit area has the high-level safety system identification, determining to start the high-level safety system.
In one alternative, the method further comprises:
and if the advanced security system is started, starting the bootloader of the advanced security system.
In one alternative, the method further comprises:
and after the advanced security system is started, the successful starting result is sent to the number writing computer.
In one alternative, the method further comprises:
if the power is off, the set-top box repeats the power-on steps S201-S203.
Making mirror images
The mirror image manufacturing is a key of the method, because the whole flash memory chip is burned in the factory mass production, then the chip is welded on the mainboard, and the running system is loaded through the program in the flash.
The image consists of three parts, one part is a universal bootloader of non-high security (advanced security system), the second part is a high security image and the high security bootloader, and the third part is a zone bit area of advanced security.
And the non-high-security bootloader is used for starting the production testing tool, starting high security after the production testing is finished, simultaneously saving a starting mark in the partition, and determining whether the non-high-security bootloader is started to the high-security bootloader or the non-high-security bootloader.
The high-security mirror image and the high-security bootloader are used for starting the high-security system which is normally started after the high-security is started.
And the advanced security zone bit area, the data of which is bound with the chip information through algorithm encryption.
Example one
Referring to fig. 3, the high safety process of the software production in the embodiment of the present application, the partitioning of the set top box is shown in fig. 4, which may specifically include:
1. after power-on, starting the non-high-security bootloader, reading the high-security flag bit region by the non-high-security bootloader, and obtaining a value by a correlation algorithm.
2. And if the high security is already started, starting the high security bootloader and starting the system normally.
3. If the high security is not started, the test method is a factory mass production mode, the bootloader starts an automatic mass production test tool, and a production line worker can test hardware assembly.
4. After the assembly test is finished, connecting a computer special for writing numbers, and writing related high-security keys
5. And after the high-security key is written, starting high security, and writing the identification bit into the zone bit area.
6. And after the high security is started, returning a successful result of the high security starting to the number writing computer, and making data statistics by the computer.
Because the process of mirror image burning is not carried out in the process, the box software can still repeat the process from 1 to 6 even if the power is abnormally cut off midway. This simplifies the work steps for the worker while ensuring that the probability of chip damage is minimized.
Thus, the production process of one box on the production line is very short, and if workers test the production quickly, one box can complete high-safety production within 1 minute.
This also ensures the security of the system because if any partition in the image is replaced, it will not boot.
Referring to fig. 5, fig. 5 provides a set-top box comprising:
the starting reading unit 501 is used for starting the universal bootloader and reading the high-level safety zone bit area after the set top box is powered on; the universal bootloader is a non-advanced safety system;
