AM4378: USB drive error

• It is also not recognized in the u-boot,

• We made two kinds of boards, designed by the same engineer. The main components in the schematic part are the same, but the size of the boards is different. As a result, the USB of one of the boards cannot work normally

Hi,

Is only this thumb drive failed? Or you have tested multiple different vendor's thumb drives which are all failed?

Does the failure also happen if you connect a high-speed usb hub then connect the thumb drive behind the hub?

I've tested a lot of usb sticks, but the error message is different

Compared with the TI reference design, we did not add a device to suppress the common mode signal on the differential data line，Does it matter?

How should I continue to check this problem, software or hardware?

Hi Jun,

We don't have enough information yet to conclude it is software or hardware issue, but if both board designs are similar and one board works the other doesn't, I would recommend to check the signal integrity first, especially you tested multiple usb thumb drives and seems they all failed. Can you please capture the usb EyeDiagram on the failure board?

Our main business is more inclined to use program research and development, so there is no relevant test equipment.In addition, our schematic diagram completely follows the reference design. In terms of PCB wiring, we also designed impedance matching and PCB manufacturers also did impedance matching.
