Dear Members
I am working on Petalinux 2015.4 and ZedBoard, I am trying to connect a CF Card through USB OTG, but the device doesnot gets registered and won't show up in /dev and I cannot mount it. Kindly help me in this regard.

Got the solution, it is as follows: 

update the device tree (system-top.dts) file to add the following entry:

/{

    usb_phy0:phy0 {

        compatible="ulpi-phy";

        #phy-cells = <0>;

       reg = <0xe0002000 0x1000>;

       view-port=<0x170>;

       drv-vbus;

    };

};

 

 

&usb0 {

        status = "okay";

        dr_mode = "host";

        usb-phy = <&usb_phy0>;

} ;
