Hi Marek,
Hi,
Since you did some work on i.MX8MP USB, may I know the status? Does host/device mode both supported in upstream?
I only have HOST option available, so for me this is only HOST.
I did not test GADGET or OTG .
Marek,
Do you still have IMX8MP USB host working on top of v2022.07-rc2, master, or imx-master? It worked for me previously at some point applying your dwc3 glue series [1] from a repo you pointed me to that I can no longer find but now I see an issue where device_probe fails:
u-boot=> usb start starting USB... Bus usb@38100000: probe failed, error -61 Bus usb@38200000: probe failed, error -61 No working controllers found
The failure is that dwc3_glue_probe fails to find 'usb3-phy' due to that being in the phy-names node of usb@38100000 and not its parent usb@32f10100
Am I missing a patch perhaps to dwc3_glue_probe in dwc3-generic.c?
