It appears as if CONFIG_USB_HOST_ETHER and CONFIG_USB_ETHER_ASIX are the problem along with CONFIG_DM_USB. Looking at the code, the #ifdef implies the DM_USB works, but apparently not in this case. I get that there might be some conflicts with the USB ETHER stuff, but does anyone have any ideas what might be wrong with DM_USB? I had to manually setup the pin-muxing and initialization. This is consistent with some of the Freescale boards, but I was hoping to reduce the some of that initialization code. adam > +#define CONFIG_MXC_USB_PORTSC (PORT_PTS_UTMI | PORT_PTS_PTW) > +#define CONFIG_MXC_USB_FLAGS 0 > +#define CONFIG_USB_MAX_CONTROLLER_COUNT 1 /* Enabled USB controller number */ > +#endif > + > +#ifndef CONFIG_SPL > +#define CONFIG_USBD_HS > +#define CONFIG_USB_FUNCTION_MASS_STORAGE > +#define CONFIG_USB_FUNCTION_FASTBOOT > +#define CONFIG_CMD_FASTBOOT > +#define CONFIG_ANDROID_BOOT_IMAGE > +#define CONFIG_FASTBOOT_BUF_ADDR CONFIG_SYS_LOAD_ADDR > +#define CONFIG_FASTBOOT_BUF_SIZE 0x07000000 > +#endif > > > I can start the USB system and it appears to find 2 USB controllers. > I have the OTG and USB H1 enabled in my device tree. > > When I start the board, the USB log on my host Ubuntu PC shows: > [26450.012906] usb 3-2: new high-speed USB device number 37 using xhci_hcd > [26455.176596] usb 3-2: device descriptor read/64, error -110 > > But it doesn't appear to be working correctly. > > i.MX6 Logic # usb start > starting USB... > USB0: USB1: USB EHCI 1.00 > scanning bus 0 for devices... 1 USB Device(s) found > scanning bus 1 for devices... 1 USB Device(s) found > scanning usb for storage devices... 0 Storage Device(s) found > i.MX6 Logic # > > USB Info seems to show the same controller twice: > > i.MX6 Logic # usb info > 1: Hub, USB Revision 2.0 > - u-boot EHCI Host Controller > - Class: Hub > - PacketSize: 64 Configurations: 1 > - Vendor: 0x0000 Product 0x0000 Version 1.0 > Configuration: 1 > - Interfaces: 1 Self Powered 0mA > Interface: 0 > - Alternate Setting 0, Endpoints: 1 > - Class Hub > - Endpoint 1 In Interrupt MaxPacket 8 Interval 255ms > > 1: Hub, USB Revision 2.0 > - u-boot EHCI Host Controller > - Class: Hub > - PacketSize: 64 Configurations: 1 > - Vendor: 0x0000 Product 0x0000 Version 1.0 > Configuration: 1 > - Interfaces: 1 Self Powered 0mA > Interface: 0 > - Alternate Setting 0, Endpoints: 1 > - Class Hub > - Endpoint 1 In Interrupt MaxPacket 8 Interval 255ms > > And the Ubuntu Host machine shows more errors: > [26507.789535] xhci_hcd 0000:00:14.0: Timeout while waiting for setup > device command > [26513.165249] xhci_hcd 0000:00:14.0: Timeout while waiting for setup > device command > [26513.373225] usb 3-2: device not accepting address 40, error -62 > [26513.373252] usb usb3-port2: unable to enumerate USB device > > I am wondering if I need to do something special to initialize the OTG > controller beyond DM_USB.
