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

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!?

1 USB Device(s) found

Scanning bus for storage devices. 0 Storage Device(s)
found

=>

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 */

#define CONFIG_EHCI_DESC_BIG_ENDIAN

#define CONFIG_EHCI_MMIO_BIG_ENDIAN

Has anybody tried sequoia?

Which exact version of U-Boot is this?

Best regards,

Real programmers don't comment their code. It was hard to  write,  it
should be hard to understand.

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

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

Cheers,
Stefan
