Part Number: AM625

Tool/software:

Hi,

My customer wants to put USB into compliance test mode.
USB2.0, High-Speed mode, Type-C connector, Host and Device.

They are asking how to configure USB.
BTW, the customer's OS is VxWorks, so they need register level configuration.

Thanks and regards,
Koichiro Tashiro

    Hi Tashiro-san,

    VxWorks is not supported on this forums. Please ask VxWorks provider for support.

    But here is some guidelines:

    - for AM625 USB in host mode, it is xHCI compliant controller, please refer to the xHCI Specification for entering test mode.

    - for AM625 USB in device mode, please refer to the DWC3 driver in Linux kernel, file drivers/usb/dwc3/gadget.c, mainly in function dwc3_gadget_set_test_mode().
