USB phy issue

Former Member
Former Member over 7 years ago

I have a customer develop a board based on 7z010, everything is ok except the usb port, they found during the linux boot, can not detect any  u-disk information. they also try it on microzed ,  both the same.

we also use a code try to read the PHY ID, return nothing, both on microzed and customer board.

Customer's board design is the same as microzed, except the number of layers.  We have test the power,reset, everything ok.

    The MicroZed is known to work in USB host mode with the Out of Box Linux. Take a look at the demo from page 28 of the MicroZed Getting Started Guide found here: http://www.zedboard.org/support/documentation/1519

     

    Give this a try and if it works then there is probably something wrong with either the hardware configuration for the Zynq PS or the devicetree.

     

    You might also make sure to more than one flash drive, if that is the USB device you are using, as they didn't all work.
