usb commands is u-boot?

The u-boot recommended by TI for the omap44xx (http://www.omappedia.com/wiki/4AI.1.7_OMAP4_Icecream_Sandwich_Release_Notes) doesn't have usb commands at the serial interface (usb start, usb reset, etc).  

Is there a reference design u-boot that does have these commands?

    Hello, 

    Have you tried u-boot from denx? To my knowledge versions later 2013.4 support usb commands.

    However depending on the board you are building your u-boot for, you may need do add some additional defines in your config file located in u-boot/include/configs.

    For example here is what is done for pandaboard in include/configs/omap4_panda.h (similar defines should be done for blaze in omap4 sdp config file in include/configs):

    /*
     * High Level Configuration Options
     */

    /* USB UHH support options */
    #define CONFIG_CMD_USB
    #define CONFIG_USB_HOST
    #define CONFIG_USB_EHCI
    #define CONFIG_USB_EHCI_OMAP
    #define CONFIG_USB_STORAGE
    #define CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS 3

    Best Regards,

    Yordan
