> Hello there,
>
> I built u-boot for mpc8315erdb from the current master @ http://git.denx.de/u-boot.git/ after enabling USB via adding the following #defines in include/configs/MPC8315ERDB.h:-
>
> #define CONFIG_CMD_USB
> #define CONFIG_USB_EHCI
> #define CONFIG_USB_EHCI_FSL
>
> But I ran into the following "machine check" after running usb start from the u-boot prompt. No USB device is plugged in. Please let me know if the above mentioned USB config options are sufficient to get the basic USB up and running.
>
> Any help in this matter is highly appreciated.

> Thanks,
