Dear Marek Vasut,
I tried using the CONFIG_CMD_USB to enable the use of the usb commands from the u-boot command prompt. However, I am getting compilation errors:
drivers/usb/host/libusb_host.a(ehci-hcd.o): In function `usb_lowlevel_init': ehci-hcd.c:(.text+0x5d4): undefined reference to `ehci_hcd_init' drivers/usb/host/libusb_host.a(ehci-hcd.o): In function `usb_lowlevel_stop': ehci-hcd.c:(.text+0x850): undefined reference to `ehci_hcd_stop' make: *** [u-boot] Error 1
You also need to enable driver for your USB host controller.

Dear Calvin Boyd,
I am currently working on a project and I am trying to load the kernel from usb instead of an sd card. How do you configure u-boot to support usb commands?
Why don't you attempt to please read the documentation first? Try "CONFIG_CMD_USB" for starters.
Best regards, Marek Vasut
