Hi Marek, et al, I'm working on cleaning up Luc's hdmi out support patchset for sunxi.
As part of this I want to also add support for usb keyboards, so as to get a full console without needing to solder wires to testpoints on some boards :) So when I plug in the usb coming from my kvm I get this: (Re)start USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... EHCI timed out on TD - token=0x80008c80 3 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found And the usb keyboard does not work. If I plug in a single usb-2 hub (no ohci support for sunxi in u-boot yet), then things do work, but after a few minutes of inactivity the usb code starts spamming the console with: EHCI timed out on TD - token=0x80008c80 EHCI timed out on TD - token=0x80008c80 ... Could this be a problem with the phy settings (iow a sunxi specific problem)? When using the kvm on my pc, the tree structure looks like this: /: Bus 06.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M |__ Port 4: Dev 4, If 0, Class=Mass Storage, Driver=usb-storage, 480M |__ Port 2: Dev 3, If 0, Class=Hub, Driver=hub/4p, 480M |__ Port 3: Dev 11, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M |__ Port 4: Dev 9, If 0, Class=Hub, Driver=hub/4p, 12M |__ Port 1: Dev 10, If 0, Class=Human Interface Device, Driver=usbhid, 12M |__ Port 1: Dev 10, If 1, Class=Human Interface Device, Driver=usbhid, 12M |__ Port 1: Dev 10, If 2, Class=Human Interface Device, Driver=usbhid, 12M Hmm, after a bit longer I also get these errors: ERROR: v7_dcache_inval_range - start address is not aligned - 0xe59ff014 Could the problem be that the usb code is feeding unaligned buffers to the ehci controller ?
