Problems solved by technology

The disadvantage of this is that the test methods of various communication boards are completely determined by the designers themselves. There are no standardized schemes and design guidelines, which makes the test operations of various boards quite different, and the test steps are also very complicated, which is not conducive to the production line. Workers master and use

Embodiment Construction

[0018] figure 1 It is a flow chart of the method of the present invention.

[0019] First create a self-starting project file for the test, so that the test program will be automatically executed after the board is powered on;

[0020] Then compile the project and write it in the flash memory of the single board under test;

[0021] Then connect the single board under test and the test PC host machine with the serial port line of the couplet, the monitor of the PC machine is used as the display terminal, and the keyboard is used as the input terminal, open the super terminal application program of the PC machine, and configure it appropriately;

[0022] Then power on the board under test. After the single board under test starts successfully, the test program will run automatically; the screen will output the test program interface and display the user input prompt;

[0023] Then the user inputs the required test item number, the program runs, and the print result is displa...

Abstract

This invention puts forward a testing method for single-board production line of communication products with central processor containing connecting the tested single-board with the testing host machine with serial lines in simple serial interface arrangement, and the single board autoamtically carries out the test code after being turned-on. Test persons can carry out the related test content byserial interface input order and put forward a compiling method for the single-board testing software which directly directs the hardware test quickly positions its mistake.

Description

Technical field: [0001] The invention relates to a single board testing method with a central processor in the communication field, in particular to a simple method for testing a single board production line of a communication product with a central processor. Background technique: [0002] Due to the rapid development of communication technology and the wide application of large-scale integrated circuits, the integration and reliability of communication products and equipment have been greatly improved. Large and medium-sized communication devices are composed of multiple hardware boards. Each board completes a corresponding function, and through cooperation with each other, the communication function of the overall device is completed. Therefore, the quality of veneer production directly affects the reliability of the overall equipment. Although the single board produced by the production line can pass the hardware test method to initially guarantee its product quality, b...
