Method for dual-mode mobile terminal to implement intermodule software continuous download

Abstract

The invention disclose a method for realizing software continuous download between dual-mode mobile terminal application modules, which only need one download interface group to realize the software continuous download between dual-mode mobile terminal application modules of multiple chip application, wherein the module and a download port of PC are connected with an analogue switch between, the module comprises a main control module and an inactive control module. The method comprises that (a), PC downloads a download guiding program to the main control module and operates the program, (b), PC sends a handshaking signal containing the download mission information to the terminal, and the download guiding program according to the signal recognizes the needed download missions, to switch download channel and start download process. The invention can use the main control module to actively complete the conversion from the inactive control module to the download mission, via the control of the main control module on the inactive control module and the download channels.

Description

technical field [0001] The invention relates to a method for a dual-mode mobile terminal to realize continuous downloading of independent programs of two modules. Background technique [0002] One of the dual-mode mobile terminals is based on a single-chip solution, and the other is based on a multi-chip solution. For a dual-mode mobile terminal based on a single-chip solution, a single digital baseband DBB (digital baseband) is relatively easy to download a program for a single Flash; for a dual-mode mobile terminal based on a multi-chip solution, the Flash of the two modules is independent, and the DBB of the two modules Control the download software separately, and download the Flash of the two modules separately. [0003] The Flash program download process is generally as follows: First, the analog baseband ABB (analog baseband) power supply, DBB reset, then run the BootLoader (startup code) in the DBB, and shake hands with the PC, and then download the RAM independent ...

AI Technical Summary

Problems solved by technology

This download method will bring some disadvantages, such as: one module downloads the program, and the other module runs the program, there may be interference between the two modules, and the download may fail; the mobile phone needs to provide two sets of serial ports, or need to provide two downloads Cable; the download method is not operable, not intelligent, etc.
