[U-Boot] Sequoia EHCI
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,

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?
