Hi.
I'm working on USB device bringup on Intel E3800 – based board. DWC3
core configured as DRD in device mode. The only connected device phy is
SMSC 3310 (USB2 ULPI). DWC3 core version is 2.10A. Gadget zero driver
can be loaded, but device enumeration fails: device is detected by host,
speed is negotiated (HS), host successfully reset device. On device side
– conndone interrupt is followed by linksts change with link_state 0.
Then host sends USBREQ_GET_DESCRIPTOR and tries to set address but
device does not react – no events generated.
I'm not sure if I hit “run/stop metastability” issue [“STAR#9000525659:
Clock Domain Crossing on DCTL in USB 2.0 Mode”]. I don't have DWC3
databook or erratum description (other than mentioned in driver code).
Can somebody provide more detailed description of STAR#9000525659?
Where can I get DWC3 Databook?
–
Thanks in advance,
Kirill
