Abstract
The present invention discloses a method for debugging and detecting a mobile phone, comprising the following steps: S1, inserting a serial conversion adapter into a USB interface of the mobile phone, wherein the other end of the serial conversion adapter is connected with a serial port of a computer; S2, outputting debugging and detecting information during a mobile phone debugging process; S3, identifying the equipment inserted into the USB interface by a USB equipment drive arranged in the mobile phone, if the equipment inserted into the USB interface is used for debugging and detecting the mobile phone, calling and sending control information including the debugging and detecting information to a USB host controller drive arranged in the mobile phone by the USB equipment drive; and S4, transmitting the debugging and detecting information to the serial conversion adapter by the USB host controller drive according to the control information, and transmitting the debugging and detecting information to the computer by the serial conversion adapter. Through the method of the present invention, hardware detection and software debugging of the mobile phone can be conveniently performed in the case of not using an evaluation board, not increasing hardware cost and not opening a cover.
Description
Technical field
The present invention relates to AccessPort technical field, more specifically relate to a kind of method of debugging detection of handset.
Background technology
The method that current mobile phone debugging detects is a lot, and the asynchronous serial port (UART) mainly utilizing mobile phone primary processor (CPU) to provide exports related commissioning information.
The method that current debugging detects has several as follows:
Detected by evaluation board debugging, evaluation board does not have size restrictions, and developer can be debugged by the emulation interface of CPU (as JTAG mouth); This external evaluation board utilize the UART of CPU export related commissioning information to PC, debugging relevant design scheme.
With mobile phone complete machine for prototype, but due to board area limited, can not emulation interface be provided, can not utilize CPU UART export Debugging message, can only screen be utilized to export limited information under brush machine pattern.
The UART pin of CPU is drawn as test point by the circuit board (PCB) of mobile phone, and mobile phone can be tested after uncapping.
Mobile phone employs multi-channel switch chip, be supported in meet industrial standard mini USB port on switch UART mouth.
In above-mentioned technical scheme, each defectiveness:
Evaluation board and mobile phone still there are differences, and can not be equivalent to completely, and not all cell phone software developer can obtain the evaluation board that cell phone manufacturer provides.
Screen output information under brush machine pattern is limited, can only play certain detection effect, helps little to software development.
Mobile phone is uncapped and is drawn UART mouth and export Debugging message to very inconvenient most software developer, moreover for the wiring of pcb board and the consideration of electromagnetic shielding, generally can not draw the UART pin of CPU.
Increase multi-channel switch chip and can solve the problem that mobile phone debugging detects on the basis ensureing not lose function and performance, but for the consideration of cost, most of mobile phone does not add the design of multi-channel switch.
