I want to set some registers to do the usb 2.0 compliant test. After I set the USBCMD and PORTSC registers with host1 controller core(The host1 core has connect to a High Speed HUB with 4 downstream facing port), there had no correct signal on oscilloscope.
USBCMD = 0x00080B00
PORTSC = 0x1C041000(Test_Packet mode)
Had you ever configed registers to done the usb 2.0 compliant test? Could you please help me. Thanks a lot.
