Abstract

The invention discloses a test method achieving USB 2.0 High Speed controlled packet sending. The method comprises the following steps that 1, a control script sends an api call instruction to a controller in PCH; 2, the controller enters a test mode after receiving the instruction, and a to-be-tested port code pattern is sent automatically; 3, an USB2.0 test fixture is connected to a server to test a to-be-tested port; 4, a differential probe is connected to the USB 2.0 test texture, and a waveform document is obtained; 5, a high-speed oscilloscope captures and analyzes the waveform document; 6, according to corresponding template comparison, whether the port meets the standard or not is judged. Accordingly, the process that a server motherboard is connected with a network card, and the system is controlled remotely through a computer to send a packet is omitted, the labor, resources and time are saved, and the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of USB testing, in particular to a testing method for realizing USB2.0 High Speed ​​control sending packets. Background technique [0002] The traditional method of controlling the controller in the PCH to make the corresponding USB port enter the test mode and send the testpacket is to install windows on the motherboard to be tested, and then install the XX software of the USB IF to the system, because entering the test mode will make all the devices under the system The USB2.0 interface is invalid (USB mouse and keyboard cannot be used). [0003] Therefore, it is necessary to use other computers to connect to the server motherboard through network cables, select the test packet to control the sending of packets through the XX software on the remote desktop operating system, and switch all the USB2.0 interfaces to be tested. [0004] Through the above process, it can be seen that the traditional USB2.0 Hig...
