We are using an OMAP5432 ES2.0 on an UEVM board
and running into issues with the dwc3 usb.
Sorry, I can't help at all. I don't have the board and I never had one.
I had ES1.0 but I never got dwc3 to work.
I have better news, re-based to 3.8.11 and it has now enumerated
the USB3 card reader at SuperSpeed.
It seems the board is very picky about what it will play host to
as neither of the mini-b to A adapters I have work. I am using
a mini B to mini B cable to run the card reader.
I have still got the disable CMD_RESET patch in.
yeah, there are a few issues regarding CMD_RESET bit on the XHCI side
with that IP. We're still trying to find a proper workaround.
Is replacing the xhci-hcd.c reset command with a call to the dwc3
driver not enough? I will leave this for the moment if it is being
worked on.
Even if we are just working in gadget mode, having the xhci-hcd driver
around causes the system to stop working.
On your mini-b to A adapters, make sure ID pin is grounded, if it's not
then the Vbus regulator won't switch to bypass mode, that's something
workable in SW, however, just lack of time to implement.
I've forced the palmas-pmic to run Vbus all the time at the moment,
as it didn't have any sort of controls for SMSP10 output 1.
Thankyou for the response.
