USB_OTG device debugging issues

1692470640 — Thu, 09 Jan 2020 06:41:24 GMT

In debugging the USB device, I encountered the following problems:
1, the first time i receive the setup package, there is no UI interruption, even though I have configured the ios in dQH, and enabled the UE bit in the UOTG_USBINTR. So I can only handle it by queryating at the moment.
2, in response to the host's first request (get the length bit 64 bytes of device descriptor), when I configure dQH and dTD and prime endpoint 0, will always enter the system error interrupt.
Please solve the problem for me, thank you!

Hi,

I have moved this thread to SDK as the USB driver is part of SDK.

regards,

Peter
