USB support in MPC8313 Board

[AVR3]

Hi ,

We are trying to add USB support in one of our MPC8313 Based card running in Linux platform and USB clock is provided from a 48Mhz crystal in the card,

Following are the steps we followed to do the same ,

 1.In Kernel config we added USB host support and Mass storage support

 2.Device tree we added USB node like below,

 usb@23000 {
           device_type = "usb";
           compatible = "fsl-usb2-dr";
           reg = <23000 1000>;
           #address-cells = <1>;
           #size-cells = <0>;
           interrupt-parent = < &ipic >;
           interrupts = <26 8>;
           phy_type = "utmi_wide";


But now when we boot the card we are getting the following error & board is hanging at this point ,

"
vfsl-ehci fsl-ehci.0: Freescale On-Chip EHCI Host Controller
fsl-ehci fsl-ehci.0: new USB bus registered, assigned bus number 1 "


if someone have some idea,could you please help to solve this issue

Do you have anything plugged into USB at this time? 

It might be good to try enabling USB under UBOOT first - just to see if it comes up correctly. You just have to write to the Enable bit in the USB controller and it should go through the initialization with the PHY. You can check that this went correctly in the error registers or the viewport.

If that works then I'd look again at the USB drivers, maybe make them as a module and reinsert them - so you can change the modules as needed.

Dear Paul Genua,

Thanks For the help

In uboot we tried enabling the usb using "USB General-Purpose Register (CONTROL)"  USB_EN bit .but we didnt see any error registers for this UTMI mode.
