    Zybo Z7-20 Tutorial Help

    @rpudelko, Did you select the correct FPGA or board from the boards? This tutorial is made for the original Zybo. It should work but you had to select your own board. Zybo Z7-20 in your case, or if you worked with FPGA parts From the warning you received it seems to me that you selected the wrong part. Regards, Bianca
  2. Hi @iqhamid, please check this topic: Also, try to change the USB cable, try another USB port and not use an external USB hub, eventually you can try connecting it to a different computer to see if you have the same behavior. Bianca
  3. Hi @cnegrea, You have a private message, Regards, Bianca
  4. Hi Enrique, If you don't have the correct drivers, different USB cables won't help. When you open Vivado do a right click on the icon and select Run As Administrator and then try again to call the path. If it doesn't work, contact the person who administrates your computer to install the drivers. If it's your personal computer, try to enable the administrator account from Computer Management. Regards, Bianca
  5. @Fulano, You have a private message with a fix Bianca
  6. Hi @Fulano, Does your device enumerate in windows? Can you see something under device manager when you connect the board? Regards, Bianca
  7. Hi @Yuanlung, You have a private message. Regards, Bianca
  8. Hi @JohnnyG, You can use the board to solder components on it, it has direct connection to the user power supply so you can power your circuit directly from there. However, if you don't want to solder components we placed a small breadboard on the package. You can stick it on the adapter or just place it there. Normally you could use the flywires to connect to a breadboard, but since you don't normally need all the wires and many of them will just get in your way, we placed the right angle connector on the adapter that is directly connected to the Discovery and you can take just what you need on the breadboard using shorter and fewer wires, so your design will be cleaner and you can see the connections easier. There is also the breadboard breakout in the package that is used to connect directly to a breadboard but that was made after this one. I hope this helps, Bianca
  9. @cfowler, Please don't remove the fuse. I'll move the thread to private @asmi, You are right, this shouldn't have happened. I know we have issues with back powering through HDMI but it shouldn't be enough to keep the board working, or burn the fuse or other components. Bianca
  10. Hi @cfowler, Normally, Adept is not build to see the ZYNQ. The fact that it showed the FPGA part, still, shows like something is working. Please make sure that when you try to see the target on Vivado, Adept is closed otherwise Vivado would not recognize the device. If with Adept closed, Vivado still doesn't recognize the target, please check, if in device manager you have the device enumerated when you connect and turn on the board. It should appear as Serial Converter, if it doesn't show up at all or enumerates as unknown device or in some other way, please let me know. If it shows as unknown device, I am also interested in the Hardware ID in the Properties -> Details tab. When you say, you are "ONLY left with a dim led that turns on and off with the board" you say that the light is dim compared to how you remember it before the event but otherwise it works well like turning on when you switch the board on, or that is flashing and resets the board? The values provided on the measurements above, show that the power supplies are working and they provide the desired voltages. Please also give me the serial number of your Zybo, you can find it on the bottom side or on the box. Regards, Bianca
  11. Hi @edwin001, Normally, it should be able to provide the +/- 0.1% with the factory calibration. I can't tell what kind of event caused the device to have a not very accurate factory calibration on certain scales. The good news is that the device is not defective, however, it does imply that if you want to use the user calibration, you have to calibrate the ranges you might use. If you want to have all the the functionality, then all the ranges need calibration Best regards, Bianca
  12. Just to add to what Cristian said, What do you mean by lower accuracy and on what scales? are you setting each scale for each reading when performing the measurements? If you are doing a measurement on 5A for 200mA the results will be lower in accuracy. Are these errors constant on all the resistance and current scales, or just one here and there? Can you point out which scales have issues? We would like to see some example of a measurement that you say it's giving errors. Is the accuracy 0.2 instead of 0.1 or we are talking about 1% or greater? The accuracy of 0.1% should be with the factory calibration. Regards, Bianca
  13. Hi @sktam We contacted Xilinx to ask about the Vivado support with the Digilent cables and they said that the latest public hw_server (2019.2) supports Digilent cables programming Versal devices. Therefore if you have a Digilent cable you can continue using it for vck190 eval board and on your “chip-down” Versal design. Best regards, Bianca
  14. Hi @sktam, We don't have an answer for you yet as we never tested the Versal with our programming solutions nor have heard anything from Xilinx. We know that Versal has a new High Speed Port for Programming/Debugging but not if it still supports JTAG config and debugging. We'll get back to you as soon as we have an answer. Best regards, Bianca

    Altium Files

    @elAmericano Hi Jerome, To add to Ana-Maria's answer, most of our products are not open source. We have some chipkit boards that are open source and therefore we had published the eagle project with all their files. The rest of the products are not open source, therefore we are not releasing the project files. We are providing the PDF of the schematic (without the proprietary programming solution) for users to be able to have access to the main components on the board and not rely just on the XDC files when they're developing the projects. It's also a good way to troubleshoot in case something is not behaving as you expect. I understand that developing from scratch is a lot of work. I've taken your request to legal department. You have a private message regarding your request.... Bianca

    Arty a7

    You can download Vivado from here: https://www.xilinx.com/support/download.html Regarding the version, you can chose whatever you want. Most of our projects with Arty A7 are in Vivado 2018.2, so if you want to open the projects and give them a run without updating IPs you can try to use the same version. It can be found in Archive: https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/vivado-design-tools/archive.html Here you have info's about the installer: https://www.xilinx.com/support/installer/installer-info-2018-2.html Basically, what it does is to download an executable that you need to run. Once you run it will start to download and install the vivado. Keep in mind that you need ~30GB space on your disk at installation and you will also need a Xilinx account. and when you install make sure you check the WebPACK which is the free version. From this point is just a standard installation. Good luck Bianca. PS: We have an older installing tutorial for 14.3 version of Vivado. Like I said, you can find a bunch of tutorials, to help you, but you need to take some time and read through them. The getting started tutorial I've pointed to you in the above response, starts with a link to Installing Vivado. I think the licencing for webpack is changed from when the tutorial was made. I don't know if you still need a licence. The chapter is covered in the tutorial, but I think that from 2018.1 for webpack you don't need anything else besides installing the sw. https://reference.digilentinc.com/learn/software/tutorials/vivado-install-guide/start

    Arty a7

    Hi @Isa5555, Have you looked at our getting started tutorials? https://reference.digilentinc.com/vivado/getting_started/start On the Reference page you have documentation, tutorials and projects to help you get started with the board. https://reference.digilentinc.com/reference/programmable-logic/arty-a7/start Regards, Bianca
  21. Hi @t-bone, The WaveForms can import Comma Separated Values (.csv) and Tab-Delimited Text files (.txt). Regards, Bianca
  22. Hi @Christoph Gollinger, Thanks for waiting. So, the issue was that when it was implemented the fine tuning for the new version of waveforms, it seems it has broken something and you can see that jitter. With our setup we could see what you was seeing with yours. We switch to an earlier version of waveforms and everything worked fine. We still have to investigate why the issue has appeared and how we can fix it without giving up to the new feature. Meanwhile, if you want to make your experiment and not experience the jitter, I recommend you to use an older version of Waveforms. We tested in 3.10.9 and it worked fine. Can you test it with this version and let us know if you still have troubles? You can find it here: https://reference.digilentinc.com/reference/software/waveforms/waveforms-3/previous-versions Regards, Bianca

    Arty A7

    Hi @Mohan_Raj_Sony, You can access the pins through the XDC of the Arty A7 just as you do with the PMODS. As for the analog sensors. they can be interfaced through the Analog pins in the shield, however, it is not 5V compatible. Anything above 3.4V will damage the FPGA. For more details please consult the reference manual of the Arty A7 https://reference.digilentinc.com/reference/programmable-logic/arty-a7/reference-manual Regards, Bianca
  24. Hi @Christoph Gollinger, Thanks for your patience. Like James said, we were able to reproduce the error and it's not due your set-up. From the hardware point of view we couldn't find the errors while investigating the discovery so we hope to be able to fix this with software. However, our colleague responsible with Waveforms is on medical leave. We'll return with an answer as soon as possible. Best regards, Bianca
