This could be solved by moving USB to driver model. Yes, that is what I was thinking too. Marek do you know if anyone is looking at this? Actually I was about to ask you (Simon) if you are looking into converting the usb stuff to dm, AFAIK no one else is working on this. I think Marek is busy for a while. I'd like to get PCI over the line first, and I have a few other things on my plate. But I think it would not be too difficult to move the usb_lowlevel_init() stuff into driver model. That would solve the primary problem I think. I'll see how things look later in the month. Regards, Simon ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Thanks for the explanation Hans. At U-Boot time, the only USB device I would need is the keyboard, and I would rather avoid adding a hub if I don't otherwise need one, so perhaps I can build U-Boot with the OHCI driver enabled instead of EHCI? I tried removing CONFIG_USB_EHCI and adding: CONFIG_USB_OHCI_NEW CONFIG_SYS_USB_OHCI_BOARD_INIT CONFIG_SYS_USB_OHCI_CPU_INIT CONFIG_SYS_USB_OHCI_REGS_BASE=0x01c14400 CONFIG_SYS_USB_OHCI_SLOT_NAME=sunxi_slot_0 CONFIG_SYS_USB_OHCI_MAX_ROOT_PORTS=1 which built and ran, but gave the error unknown command usb. Can this approach be made to work? Cheers, B.R. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
