john_joe Posted March 17, 2020 Share Posted March 17, 2020 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.

john_joe Posted March 18, 2020 Author Share Posted March 18, 2020 Rebuilding the petalinux using the solution from @Andy7777 did solve the problem. Quote 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>; }; Link to comment Share on other sites More sharing options...

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.
