  1. Hello @JColvin, thank you for your answer! The examples are tried: https://github.com/Digilent/Zybo-Z7-20-pcam-5c/tree/master Working , but with Vivado 2017.4 and 2019.1, but no Vitis 2020.1 version available. Embedded Vision Demo https://digilent.s3-us-west-2.amazonaws.com/resources/whitepapers/EmbeddedVisionDemo.pdf?_ga=2.93591453.1253467320.1595997339-1751738775.1593952945 Working , but with Vivado 2017.4 only. No 2020.1 version available. Petalinux-Zybo-Z2-20 https://github.com/Digilent/Petalinux-Zybo-Z7-20/releases Only very old Vivado 2017.4 available. Binaries installable but not booting rootfs on SD-Card. Not working in Ubuntu 20.04. Xilinx Petalinux not working on Ubuntu 20.04. Xilinx Petalinux Python version conflicts. Xilinx Petalinux not installable as root with sudo to /opt. Xilinx Petalinux not booting from SD-Card Zybo-Z7-base-linux https://github.com/Digilent/Zybo-Z7-20-base-linux Only available for Vivado 2017.4 with TCL Scripts..., Not working. Further Examples I tried: Zybo-Z7-20-DMA https://github.com/Digilent/Zybo-Z7-20-DMA/tree/master Zybo-Z7-20-DMA: Vivado 2018.4 not installed on my system (already 120 GB occupied by vivado tools), Vitis 2020.1 not available. Zybo-Z7-20-Pmod-VGA https://github.com/Digilent/Zybo-Z7-20-Pmod-VGA/tree/master Vivado 2018.2 not installed on my system, Vitis 2020.1 not available. Zybo-Z7-20-XADC https://github.com/Digilent/Zybo-Z7-20-XADC/tree/master Stable tree is 2018.2, I did not see the development tree for 2020.1, I will try that soon... I think the Xilinx way with resource exhausting, obfuscating, and version-incompatible development tools, especially the tcl scripts is too complicated and error-prone compared to Intel Quartus... What I also don't like is that Petalinux is very far away from vanilla Linux and not installable as root user like every other Linux program. If you try to install Petalinux, It takes a long time before it gives up with errors. Another Question: Is there any support for using Vitis AI on the Zybo Z7-20 available? Best regards Fabian
  2. Hello, I have been working with Intel/Altera FPGA for several years now. I recently bought a Zybo-Z7-20 (July 2020) because I am interested using the Zynq ARM+FPGA SoC for solving contemporary problems. To get started, I tried to follow your instructions at https://reference.digilentinc.com/reference/programmable-logic/zybo-z7/start Unfortunately, I cannot get any Project running without errors in Vivado, Vitis or Petalinux. Most of the given tcl scripts don't succeed to create Vivado project files, and even if this works, I tried Vitis 2020 and event the hopelessly outdated 2017 and 2018 versions in the mainstream Ubuntu Linux 2020.04 LTS. Finally, I ended up in installing 120 GB of different Vivado versions and lost a huge amount of time, which makes absolutely no sense to me! This is very frustrating! All the examples are hopelessly outdated (from the year 2017!!!) and not working any more. Please Digilent, do your homework and give recent and working examples for the current Vivado/Vitis 2020 development environments if you sell your high-priced products to your customers in 2020. Since the Zynq 7000 is listed as supported with Vitis-AI, please give also Instructions for the Vitis-AI library for using the board for contemporary AI problems. Best regards Fabian
