petalinux-boot cannot find fpga device

Now I got this problem 

$petalinux-boot --jtag --prebuilt 2

It says no FPGA device found, but I have installed adpet runtime and util, and I can see this board as

$ sudo djtgcfg enum

Found 1 device(s)

 

Device: Zybo

    Product Name:   Digilent Zybo

    User Name:      Zybo

    Serial Number:  210279760033

Do I need to install some driver for petalinux?

 

[dakefeng]

well, I am using vivado 2015.4 on linux. UG973 says you need to run install_drivers manually with sudo to install the driver..

Ok, I did that, but I still didnot see /dev/windrvr6 device, And I checked the install_drivers directory, it is suspiciously empty, only two rules files and two simple script to copy them. What should be the right solution?

Many thanks.

Have you tried to unplug the Zybo after running install_drivers? The driver needs to be associated with the device again.

Spent 50$ to upgrade my parallel to 11, installed ubuntu 16.04, redo everything. it is connected now. still haven't found the problem.

 

BTW what is the device name for digilent fpga program cable under /dev?

 

[BKallaher]

The Zybo will show up as a ttyUSB device. To find out which device is the Zybo run 

ls /dev

Then plug in the Zybo and rerun the command. By comparing the outputs of the two you should be able to find the new entry in the directory. The new entry is the serial port of the Zybo.

thanks, I saw them.
