I don't know of an ehci-ppc4xx.c file. Did you create it yourself?

I created the file by myself. But it's nothing more than setting up register base addresses similar with ehci-ixp4xx.c ...

I checked out from current source a few days ago. Maybe it's not very straight forward to get ppc4xx support working (as I originally thought). I'll take a look later this week.

thanks,

Chris

I'm getting the following message when issuing "usb start" .

Maybe the USB cable is bad?

Cannot reset port 1!?

#define CONFIG_USB_EHCI_PPC4XX /* added ehci-ppc4xx.c similar as

I don't know of an ehci-ppc4xx.c file. Did you create it yourself?

Cheers,

You should always base your work on the latest version available in the git tree.

That would be great. EHCI support for PPC4xx would be nice to have.

Thanks.
