AM5728: USB2.0 test mode

Part Number: AM5728

Hi,

I have one question regarding AM5728 USB2.0 test mode.

I would like to know how to enter to the USB2.0 test mode.

I already checked TI Wiki "Linux Core DWC3 User's Guide". But my customer's OS is not Linux.

According to the TI Wiki, there are two ways of entering Test Modes with DWC3.

Sending properly formatted SetFeature(TEST) Requests to the device

Using a non-standard DebugFS interface

I think DebuFS is for Linux. So another one "SetFeature" is for my customer, I think.

For "SetFeature", does DWC3 of AM5728 need to configure any registers? If register setting is needed, please let me know register's information.

I appreciate your quick reply.

Best regards,

Michi

Typically we don't support non-Linux USB driver development, but if you want to enter the test mode in the USB host mode, please refer to the xHCI Spec, which describes the procedure. Or if you want to enter the test mode in the USB device mode, you need to set the corresponding test mode in the DWC3 DCTL register.
