Zybo: Error opening JTAG UART @ localhost:-1

[Troy]

Hi, I get the error message: Error opening JTAG UART @ localhost:-1

when trying to run the lwip echo server implementation in Xilinx SDK. Has anyone else run into this issue and have a solution?

Thanks,

Troy

Actually, I hadn't noticed this before but SDK is actually crashing now when I press a button on the Zybo board.  I opened up screen /dev/ttyUSB1 115200 and can see the log messages just fine, so it must be something in Vivado that's messing up.  I start Vivado in a console and can see this from it: crash.txt, which references this: hs_err_pid13046.log.

Searching for that error messages yields this post on the Xilinx forums.  The solution posted by an admin is to use an older OS version.  I already bent over backwards to get a VM of Ubuntu 14.04.4 LTS so that I could run this, I don't think I'll be wasting my time downgrading.

I guess the solution here is use screen to access the serial console.

Hi @zuleikha,

Here is an Avnet forum thread that goes through a few possibilities and some solutions to the "No Target with ID 64 in the System" error. I would also suggest to go through Getting Started with Zynq tutorial. Here is our resource center for the zedboard as well

cheers,

Jon

Hi again@jpeyron It works with a simple test application ''hello world''but when I tried it in my application that aims to write in the PMods, the same message is displayed as attached in the screen-shot below.:'(

Thank you so much Jon

It works

Hi @zuleikha,

You also need a usb cable connect to the uart on the left side of the board at J14. I have attached a screen shot of the two usb connections needed to program(J17) the zedboard and communicate through uart(J14).

thank you,

Jon

Hi @jpeyron

I am using windows 8 64 bit

In my laptob, I am using now two USB ports (one for the mouse and the other one for the zedboard)

Regarding the mini usb port used in my zedboard is JTAG port exactly as in the link : http://www.macs.hw.ac.uk/~rs46/files/zedboard-setup.jpg

Many thanks!

Hi @zuleikha,

What OS are you using i.e. linux, windows...? If you are using linux did you install the cable drivers as shown here. Do you have two usb cables connected one to program and one for the uart?

thank you,

Jon

Hello all;

I am trying to send ".elf" file to my board using a A USB to B USB cable (JTAG mode jumpers is correctly positionned),I have the same issue mentioned above (attached in the screen-shot)

Knowing that I use SDK 2017.3 and the green led on the zedboard is lighted up when the 'C' code source is ran! 

Everything seems to be fine with the plugging. 

even connecting STDIO to console JTAG UART in the run/debug configuration does not resolve the problem!

Any help will be appreciated 

 

HELP HELP

Thank you

Hello gkelly,

I'm sorry for the late response. Wanted to confirm if you are you still experiencing problems with the serial communication in the getting started with Zynq tutorial or did you resolve your issue? If you are still experiencing problems I would like to help you get them resolved.

thank you,

Jon

Thanks @JColvin!  I should have also mentioned that I'm using Vivado 2016.1.

Hi gkelly,

I have asked some of our applications engineers about this; they will get back to you here on the forum.

Thanks,

I had the same issue following Getting Started Guide.  The board is programmed and is responding to the switches and the RX light blinks whenever I press a user button, but nothing shows up in the Console tab of the SDK.

I got a little further than the original poster in that I added myself to the dialout group (adduser $USER dialout), and logged out and back in.  This made the SDK able to open /dev/ttyUSB1, which I then configured like this:

However even after doing this and restarting the SDK and replugging the board I still can't get any output.

On my board JP5 is set to JTAG.

Any ideas?

Huh, this is a pretty broad question, can you give me any more specifics on your hardware, like jumper settings and anything else? Does your computer recognize the Zybo when it's plugged in? In device manager it pops up as USB serial converter A/B. If these don't pop up, have you installed the cable drivers?

[Troy]

I'm using 2015.4

[TommyK]

I looked it up and it seems to be a bug in old versions of SDK. Are you using a recent version of SDK?

Hi Troy,

I personally don't know the answer to your question, but I have asked some of our applications engineers about this; they will get back to you here on the forum.

Thanks,
JColvin
