The OTG link is in usable shape, but the EHCI one isn't. On Wednesday 10 December 2008, Felipe Balbi wrote: > > > > What are the issues ? I have a prototype Overo and one issue there is that the GPIO to let the EHCI port supply VBUS power isn't hooked up! I know how to modify that board, but somehow that keeps slipping off my radar ... :) I don't know the details, but the big problem with EHCI on OMAP3 is evidently some kind of silicon issue that shows up through the transceiver hookup and prevents the link from being reliable. I'm told that some boards using that without a transceiver -- for on-board communication, not for an external link -- have been successful. Folk at TI were looking at those issues; I don't know if they've been resolved yet, e.g. in the ES 3.0 silicon. > It think it still has a problem during probe.

That's a newish problem, but is not -- from what I've been told -- the Real Issue with EHCI on OMAP3. - Dave -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
