Unable to Connect to Zedboard Target in Vivado via JTAG (Not Micro USB)

[khobbit]

I need to use the JTAG header to program the Zedboard, since the MicroUSB connector is physically damaged.

I cannot find any documentation or forums about how to use the JTAG connector for programming the FPGA, so I am going to ask for your help.

I have a basic design in Vivado for making switch 0 toggle led 0. The bitstream is ready to be sent to the FPGA. However, when I try to connect to the hardware, by clicking "Open target", it is unable to connect.

When I try to manually connect:

I am using Xilinx Platform Cable USB adapter for connecting the JTAG to the computer's USB input:

I have the driver installed, and it appears in my list of devices when plugged in, and disappears if I unplug it, and is up-to-date:

I suspect the jumpers may not be configured properly? But again I cannot find clear documentation on how to set this up. This is how mine is set up:

Here is some information about my computer:

I am using Vivado 2016.1, since that is used in a lot of the tutorials. I think the Diligent tutorial uses 2016.2. It also comes with the Zedboard board file, although I downloaded the one made by Diligent as instructed in the tutorial.

I hope I have provided enough information. I appreciate any help!

Hi @khobbit,

I don't believe Digilent has a tutorial that uses 2016.2, the three primary guides we have for getting started with Vivado are in 2016.4 (link), 2018.2 (link) and 2020.1 (link).

Regardless, based on the screenshot in your device manager, the problem you are encountering is a bug with the Xilinx installation script that doesn't install their drivers correctly. You can fix this by following the steps outlined in this specific post:

Thanks,

Hello @JColvin. I am not sure how to follow those steps since the C:\Xilinx\Vivado\2016.1\data\xicom\cable_drivers\nt64\dlc10_win7 directory does not exist for me:

Also here is what's inside of the diligent directory:

If I try going there in the command prompt:

I also tried following the instructions on pg.28 of the Vivado Design Suite User Guide ("Installing Windows Driver"), however it is not clear what to put for %log_dir%. I am not sure where this log directory is supposed to be. I tried both "install_drivers_wrapper.bat" as well as "install_drivers_wrapper.bat %log_dir% %log_dir%" since I was not sure which way was correct. But still it is not working afterward.

@JColvinI just now tried running those four commands inside of the nt64 directory instead, since I noticed those files were there, but it is still not being detected by the hardware manager:

When I plugged in the cable, this is what I see in device manager:

I noticed it is not called "Xilinx USB Cable" as you mentioned, however I followed the steps quite carefully so I am not sure why it is still called "Xilinx Embedded Platform USB Firmware Loader".

@JColvinI got it to work! I just forgot to check the box when uninstalling the driver. I was now able to successfully program the Zedboard!

Hi @khobbit,

I'm glad to hear you were able to get it working!

Thanks,
