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 was trying to get EHCI running on sequoia board (ppc440epx).

EHCI is currently not supported in U-Boot for PPC4xx.

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

Cannot enable port 1 after 5 retries, disabling port.

Maybe the USB cable is bad?

Cannot reset port 1!?

EHCI works fine under operating system (a customized NetBSD). This is the configuration I'm using,

.

#define CONFIG_USB_EHCI

#define CONFIG_USB_EHCI_PPC4XX /* added ehci-ppc4xx.c similar as ehci-ixp4xx.c */

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

Cheers, Stefan
