No devices detected on target

Hi, All

When I try to open my vivado 2018.2 hardware manger and connect to my zynq 7020 board, I got this error

open_hw_target
INFO: [Labtoolstcl 44-466] Opening hw_target localhost:3121/xilinx_tcf/Digilent/2102498xxxxx
ERROR: [Labtools 27-2269] No devices detected on target localhost:3121/xilinx_tcf/Digilent/2102498xxxxx.
Check cable connectivity and that the target board is powered up then
use the disconnect_hw_server and connect_hw_server to re-register this hardware target.
ERROR: [Common 17-39] 'open_hw_target' failed due to earlier errors.

I notice that it seem the usb cable is disconnected when the vivado try to open target, and dmesg as below

[ 39.042560] usb 1-1: new high-speed USB device number 8 using xhci_hcd
[ 39.201474] usb 1-1: New USB device found, idVendor=0403, idProduct=6014

Anything I miss?

I am on a Ubuntu 18.04

Re: No devices detected on target

Hi @jimmystone,

Vivado 2018.2 supports Ubuntu 16.04.3 LTS (64-bit). Please use the supported OS. If you try to use unsupported OS, Vivado Functionality may be as not expected.

For more information please refer page 11 of UG973 (v2018.2).

 

For Zynq 702 Board, based on revision of the board please use corresponding Vivado/ISE version from this link https://www.xilinx.com/products/boards-and-kits/ek-z7-zc702-g.html#documentation

 

And for the error you are facing, please ensure that there is no Dip in any Voltages, all the time.

Hope this helps.

Regards,

Deepak D N

Re: No devices detected on target

Hi, ddn

I had tried it on Win7 with vivado2015.4 lab verison, and got the same issue.

I can succefully boot my zynq with an SD card, the configure done LED is on when I boot with SD card. So I think my FPGA board seems OK

I also try a new power adapter and connected the usb cable directly to my desktop, the same issue with my JTAG.

Any idea?

Re: No devices detected on target

Hi @jimmystone,

Please go through this ZC702 Debug checklist, and confirm me till step 2 you are fine?

Try with different cable to initialize the JTAG chain? so that we can eliminate that problem is not due to cable.

In Step 3 check whether you are able to detect JTAG USB cable is getting detected in device manager? If not,  please Try reinstalling the USB drivers by following this AR#59128. After try initializing the JTAG chain after power cycle.

If the Cable is getting detected, but JTAG chain is not getting initialized, try slowing down the cable speed (Output > Cable Setup).
