Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] The main idea of ​​the present invention is: through the virtual serial port characteristics of the CDC USB device, the burning data sent by the electronic terminal device that performs the burning data function is transmitted to the multimedia chip, and the multimedia chip receives the burning data through the multimedia chip and the baseband chip. The serial port between transmits it to the baseband chip to complete the burning.

[0033] The virtual serial port characteristic of the CDC class USB device used in the present invention is based on the abstract control model under the traditional pure telephone service model (POTS) in the CDC class USB device protocol family. CDC class USB is the abbreviation of Communication Devices Class USB, which includes two interface subclasses: communication interface class and data interface class. The former is used for...

Abstract

The invention provides a system for burning a baseband chip in a double chip scheme. The system comprises electronic terminal equipment for executing a data burning function, the baseband chip and a multimedia chip, wherein the baseband chip is connected with the multimedia chip by virtue of a serial port, the multimedia chip is connected with the electronic terminal equipment by virtue of CDC (Control Data Corp) USB (universal serial bus) connector equipment virtualized to a serial port, and the multimedia chip is used for receiving and transmitting burning data from the electronic terminal equipment. The invention also discloses a method for burning the baseband chip in the double chip scheme. The system and the method can be used for reserving at least two serial ports in a baseband chip burning process.

Description

technical field [0001] The invention relates to the technical field of information data writing, in particular to a system and method for programming a baseband chip under a two-chip solution. Background technique [0002] At present, communication devices such as mobile phones mostly use a dual-chip solution of a baseband chip and a multimedia chip. The baseband chip is used to communicate with the wireless network, and the multimedia chip is used to realize functions such as audio and video playback, display, and photography. The two chips are connected through a serial port. . [0003] In the prior art, there are three methods of burning multimedia chips: serial port burning, USB interface burning and offline mode burning, while the baseband chip can only use serial port burning. Thus, the multimedia chip is completed under the dual-chip solution. The matching methods with baseband chip programming are as follows: [0004] 1. The baseband chip and multimedia chip are pr...
