Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 As shown, there is a serial port 3 for connection between the communication processor 1 and the application processor 2 of the mobile phone, and the serial port 3 is used for information exchange between the two, wherein the application processor 2 is used as the main control terminal to control the communication processor 1 , the display screen 5 is directly connected to the application processor 2, and the application processor 2 can send data to the display screen 5 and display the data.

[0032] After the communication processor 1 crashes, there are two problems to be solved in the way of sending data to the application processor 2 through the serial port 3. First, if the application processor 2 is in a sleep state and cannot receive serial port messages immediately, it is necessary to wake up the application processor 2 firs...

Abstract

The invention discloses a method of the fatal wrong information offhand displaying of a mobile phone communication processor. When the procedure running of the communication processor occurs fatal wrongs, the communication processor switches to the shut off managing step; firstly the communication processor proceeds the lock intermitting operation to other hardware devices, then messages of the fatal wrong information status is sent out by changing the height of one connecting line power level between the communication processor and an applying processor; the applying processors respond the change intermitting of the power level and stop all current operations comprising the mutual operation of the applying processors as well as a communication processor, the serial buffer is deleted and the fatal wrong information is prepared to be received; the communication processor resets the serial hardware to send the fatal wrong information to the applying processors through the serials; finally, the applying processors display the information out after receiving the fatal wrong information, thus quickly and effectively discovering as well as solving the fatal wrong information of the mobile phone communication processors.

Description

technical field [0001] The invention belongs to the technical field of mobile communication terminals, and in particular relates to a method for displaying fatal error information in a communication processor software program in a mobile phone. Background technique [0002] More than two processors are often integrated in current mobile communication terminal products, one of which is an application processor used to control the terminal product, and the other is a communication processor used to control mobile communication functions. If it is a dual-mode machine, it includes two communication processors, and one of the processors is used as an application processor at the same time. Information exchange is performed between the application processor and the communication processor through a serial port, and usually the application processor acts as a master control terminal to control the communication processor. [0003] The processor is controlled by software, as long a...
