Problems solved by technology

[0002] At present, with the increase in the demand for industrial motherboards and the increase in the use of peripheral modules, it has become an inevitable choice to increase the USB ports of the motherboard. Such motherboards with multiple USB ports have emerged as the times require. However, in the PCBA production process, it is necessary to manually check whether the USB ports are soldered properly. A single plug-in U disk increases labor costs and increases production time
There is no mature test method for the multi-USB port test of the motherboard developed by the RK3399 platform. Usually, insert a U disk, judge a USB port, unplug the U disk, and then insert the U disk into another USB port for testing. 20 USB ports need to be unplugged. 20 times, it takes 3 minutes for 20 U disks to pass the test normally, and the efficiency is relatively low

Embodiment Construction

[0010] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0011] see figure 1 , the embodiment of the present invention includes:

[0012] A method for testing multiple USB ports on an RK3399 mainboard, comprising: testing multiple USB ports by polling a U disk mount test and a data transmission test; Whether the disk is successfully mounted, if the mounting is successful, the data transmission test is performed on the U disk, and if the data transmission is successful, the test ends.

[0013] The U disk mount test includes inserting several U disks into 20 USB ports on the RK3399 motherboard, clicking the test software to test the U disk mount situation, if all U disks are successfully mounted, then p...

Abstract

The invention discloses a method for testing multiple USB (Universal Serial Bus) ports of an RK3399 mainboard. The method comprises the following steps of: polling to test the multiple USB ports through a USB flash disk mounting test and a data transmission test; wherein the USB flash disk mounting test comprises the steps of mounting a USB flash disk on an RK3399 mainboard, testing whether the USB flash disk is successfully mounted or not, if the USB flash disk is successfully mounted, performing the data transmission test on the USB flash disk, and if the USB flash disk is successfully transmitted, ending the test. By means of the mode, a plurality of USB ports can be tested in a single batch, and the testing efficiency is high.

Description

technical field [0001] The invention relates to the field of RK3399 motherboard testing, in particular to a motherboard multi-USB port testing method developed based on the RK3399 platform. Background technique [0002] At present, with the increase in the demand for industrial motherboards and the increase in the use of peripheral modules, it has become an inevitable choice to increase the USB ports of the motherboard. Such motherboards with multiple USB ports have emerged as the times require. However, in the PCBA production process, it is necessary to manually check whether the USB ports are soldered properly. Inserting and unplugging the U disk individually increases the labor cost and increases the production time. There is no mature test method for the multi-USB port test of the motherboard developed by the RK3399 platform. Usually, insert a U disk, judge a USB port, unplug the U disk, and then insert the U disk into another USB port for testing. 20 USB ports need to b...
