I can switch back and forth and device mode works each time, host mode remains
Probably the failure happens if some step(s) in dwc3_core_init() hasn'tI saw the experiment you did from the link you provided. We want to also
tusb1210 is a phy driver right? The issue is probably because we didn't
initialize the phy yet. So, I suspect placing dwc3_get_extcon() after
initializing the phy will probably solve the dependency problem.
You can try something for yourself or I can provide something to test
later if you don't mind (maybe next week if it's ok).
Yes, the code move I mentioned above "moves dwc3_get_extcon() until after
dwc3_core_init() but just before dwc3_core_init_mode(). AFAIU initially
dwc3_get_extcon() was called from within dwc3_core_init_mode() but only for
case USB_DR_MODE_OTG. So with this change order of events is more or less
unchanged" solves the issue.
confirm exactly which step in dwc3_core_init() was needed.
