Fig. 7 is a flow chart illustrating switching of the operation mode of the display device according to the configuration file in the first memory according to some embodiments of the present invention.
Referring to fig. 7, in this embodiment, after the radio frequency detection station is started up, according to a serial number SN in the first configuration file, a Manufacturing Execution System (MES) acquires an MAC address of a bluetooth module of the display device and an MAC address of a WIFI module of the display device from the MES, writes the MAC address of the bluetooth module into the second configuration file, and writes the MAC address of the WIFI module into the third configuration file.
And burning the first memory by a preset burning tool, and writing the zone bit in the fourth configuration file in the first memory. The information of the zone bit mainly comprises two parts: the first part of information is "PB", and the second part of information is "WF" or "AB". "PB" represents address writing, "WF" represents entering user mode, and "AB" represents performing bluetooth radio frequency detection mode.
After the burning is finished, the display equipment is restarted, the zone bit of the fourth configuration file in the first memory is read, if the zone bit contains information AB, a Bluetooth radio frequency detection mode is entered, and the radio frequency performance of a Bluetooth module in the wireless communicator is detected; meanwhile, the radio frequency performance of the WIFI module in the wireless communicator is detected.

And if the Bluetooth module and the WIFI module both pass the radio frequency performance detection, rewriting the second part of information and entering a user mode. Specifically, the second partial information "AB" is deleted and replaced with the information "WF".
After the display equipment arrives at the next station, the display equipment is restarted, and then the correctness of the new zone bit is detected: if the second part of information contained in the new zone bit in the fourth configuration file is 'WF', the display equipment passes the radio frequency performance detection of the Bluetooth module and the WIFI module, and continues to process the next station; if the second part of information contained in the new zone bit in the fourth configuration file is 'AB' or null, it indicates that the display device has not been subjected to radio frequency performance detection, or has not been subjected to radio frequency performance detection by the bluetooth module and the WIFI module, and the display device returns to the radio frequency detection station.
Fig. 8 is a schematic flow chart illustrating the determination of the fourth configuration file in the first memory after the display device is powered on according to some embodiments of the present invention.
Referring to fig. 8, in this embodiment, after the display device is powered on, the ARM processor executes instructions starting from address 0x000000 at reset, mapping the ROM chip or the first memory on the board to this address. After the display equipment is started, the BootLoader program is loaded and executed, and the controller copies or maps the BootLoader program to the memory so as to execute the instruction of the BootLoader.
The display equipment loads a system kernel, and initializes an application program of the display equipment through a root file system stored with a kernel code mapping file; and then searching a fourth configuration file in the first memory according to the defined zone where the zone bit is located.
Under the condition that a fourth configuration file is found, if second part information of the zone bit of the fourth configuration file contains AB information, entering a Bluetooth radio frequency detection mode, and loading codes of the Bluetooth radio frequency test mode; and if the second part of the information of the zone bit of the fourth configuration file does not contain the AB information, entering a user mode and loading a code of the user mode.
And directly entering a user mode and loading the code of the user mode under the condition that the fourth configuration file is not found.
Fig. 9 is a schematic flow chart illustrating the rewriting of the flag bit of the fourth configuration file in the first memory after the display device is turned on according to some embodiments of the present invention.
Referring to fig. 9, in this embodiment, after the display device passes the radio frequency performance detection of the bluetooth module and the WIFI module, the flag bit of the fourth configuration file in the first memory is read. If the zone bit exists, the zone bit is erased, and a new zone bit containing WF information is written into a fourth configuration file; if the flag bit does not exist, the new flag bit containing the WF information is directly written into the fourth configuration file.
And after the flag bit is rewritten, restarting the display equipment again, and checking the new flag bit after restarting to confirm whether the new flag bit is correct or not. By the method, the probability of unsuccessful programming of the new zone bit is reduced.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein.
