FIG. 1 is a schematic diagram of the hardware connection of the method of the present invention, as shown in the figure: the device consists of a download port, an analog switch, a master control module and a slave control module.
The download serial port of the download port is connected to the input end of the analog switch, and the download port simultaneously outputs voltage signals to the master control module and the slave control module.
The download serial port of the main control module is connected to one output end of the analog switch and provides a switching signal of the switch for the analog switch. Meanwhile, the master control module also provides a starting signal (or a VCharge signal, or a VBAT signal and a VCharge signal) for the slave control module. If the master control module and the slave control module share the VBAT signal, only the VCharge signal is provided for the slave control module, and if the master control module and the slave control module do not share the VBAT signal, the VBAT signal and the VCharge signal are provided.
And the download serial port of the slave control module is connected to the other output end of the analog switch.
The analog switch switches the serial port of the download port to the download serial ports of the master control module and the slave control module respectively under the control of the switching signal provided by the master control module.

It should be noted that identification of the handshake signals can only be realized by a boot program, and control of the analog switch and the slave control module can also be realized by a PC side, but hardware devices and complicated software codes need to be added.
Fig. 2 is a flow chart of the method of the present embodiment, which includes the following steps:
step 1: the PC side starts a downloading thread of the main control module, downloads the downloading bootstrap program into an RAM of a DBB (database bus) of the main control module and operates the downloading bootstrap program;
it is assumed that GSM (global System for Mobile communication) is the master, and TD-SCDMA (Time Division-synchronization Code Division Multiple Access) is the slave (in other embodiments, TD-SCDMA may be used as the master, and GSM is used as the slave). In this step, the PC first provides a trigger signal (VBAT and VCharge) through the download port to supply power to the master, i.e., the ABB of GSM, and the DBB is reset, then runs the BootLoader program solidified in the GSM DBB, performs handshake with the PC, receives the download bootstrap program sent by the PC side, stores it in the RAM in the GSM DBB, and runs.
Step 2: the PC side sends a specific handshake signal containing the information of the downloading task to the terminal, the downloading bootstrap program identifies which module or modules should be started to download the task according to the signal, if the main control module program is to be downloaded, the step 3 is executed, otherwise, the step 4 is directly executed;
according to the setting of the user on the interface, the PC side sends some specific handshaking information to the download bootstrap program in the RAM in the GSMDBB, and these handshaking signals specify which modules are to be started for downloading tasks. The bootstrap program performs corresponding processing accordingly, and three results can be obtained: only downloading GSM program, only downloading TD-SCDMA program, or downloading two module programs, if there is GSM program to be downloaded, executing step 3, otherwise executing step 4.
And step 3: after downloading the main control module program according to the conventional method, judging whether to download the slave control module program, if so, executing the step 4, otherwise, ending the downloading;
and 4, step 4: starting a downloading thread of the slave control module, and simultaneously switching a downloading channel to the downloading channel of the slave control module by the downloading bootstrap program;
the download guiding program can actively send a request for downloading the slave control module program to the PC side, once the PC side receives the request, the PC side considers that the master control module program is downloaded completely, the GSM download task is immediately stopped, the TD-SCDMA download thread is started, a handshake signal is sent to the terminal through a specified port, namely a download serial port cycle, and a return value is intercepted. Meanwhile, a download bootstrap program in the RAM in the GSM DBB sets output enable of a certain GPIO (general purpose input/output port) and pulls up or pulls down, and the analog switch switches the download serial port of the terminal to the download serial port of the TD-SCDMA under the control of the signal.
And 5: the master control module simulates a starting signal of the BootLoader of the slave control module, starts and finishes program downloading of the slave control module.
After a period of time delay, a downloading bootstrap program in the RAM in the GSMDBB simulates a starting signal (or a VCharge signal or VBAT and VCharge signals) of a TD-SCDMA module through a certain GPIO or GPO (general purpose output) port of a GSM DBB, triggers the TD-SCDMA ABB to supply power externally, resets the DBB, runs a BootLoader program solidified in the TD-SCDMA DBB, and downloads the TD program.
It should be understood that those skilled in the art to which the invention pertains may make corresponding changes or substitutions according to the technical solutions and concepts of the present invention, and all such changes or substitutions shall fall within the protection scope of the appended claims.
