USB host not recognized in Pynq v2.5 retargeted on the Zybo-Z7-20

Question

Hello everyone,

I retargeted Pynq v2.5 on the Zybo Z7-20 and tested few things and it is working fine, for example, accessing jupyter or adding custom overlays, etc.

However, when I try to use it as a USB host (I am shorting jumper JP1) it does not recognize a pendrive.

I try lsusb and it shows nothing. I was able to mount the pendrive using a PYNQ-Z2 image v2.5 and the pendrive is mounted.

Is there any way to solve this?

Thank you.

Rebuilding the petalinux using the solution from  @Andy7777 did solve the problem.

I know this is an old link, but in case anyone is still interested, i managed to get this working by changing the system-user.dtsi file to

/include/ "system-conf.dtsi"
/ {

        model = "Zynq Zybo Z7 Development Board";
    compatible = "digilent,zynq-zyboz7", "xlnx,zynq-7000";

    chosen {
        bootargs = "console=ttyPS0,115200 earlyprintk uio_pdrv_genirq.of_id=generic-uio";
    };

    usb_phy0: usb_phy@0 {
        compatible = "ulpi-phy";
        #phy-cells = <0>;
        reg = <0xe0002000 0x1000>;
        view-port = <0x0170>;
        drv-vbus;
    };

};

&usb0 {   
    dr_mode = "host";
    usb-phy = <&usb_phy0>;
};
