No hardware target is detected [Nexys4 DDR]

[conanandai100]

Hi all,

I recently got a Nexys4 DDR board. When I tried to test it, there seemed to be no target detected:

I tried to reinstall the usb-jtag driver by following the solution:

But didn't work. My vivado version is 2017.2.

Can anyone who worked with this device before offer any advice?

Thanks a lot.

Hey @conanandai100,

If I remember correctly, the Digilent boards require the Digilent Adept drivers to be properly recognized.

Maybe this helps,

Hi Herbert,

Thanks for your quick reply.

Yes, I used to have a Nexys2, which worked well with digilent adept. But this Nexys4 DDR didn't, with a "No Device Connected" in the GUI. That's why I am a little bit confused now. 

I checked the jumper of JP1 also, which is on the JTAG mode.

Hey @conanandai100,

Thanks for your quick reply.

You're wecome!

But this Nexys4 DDR didn't, with a "No Device Connected" in the GUI.

That's why I am a little bit confused now.

Depending on the operating system there can be problems with access rights and usb device configurations.

Last time I used it, the djtgcfg tool was very helpful in narrowing down the problem.

Hope this helps,

Herbert

Hello,

Thanks for the reply.

I am using Windows 8.1. I had tried to reinstall the driver before I posted this topic but it didn't work.

This morning I figured out that the simplest solution was to install Vivado 2015.1 and the diligent board worked well. For Vivado 2014.2 and 2017.2, it didn't. I will try later by installing the windriver then.

Best
