  1. Hello everyone, I am new to Petalinux. I have couple of questions. I am using PetaLinux SDK version "2018.3 when I do petalinux-config --get-hw-description=../ i get the following: WARNING: Your PetaLinux project was last modified by PetaLinux SDK version "2017.4", WARNING: however, you are using PetaLinux SDK version "2018.3". Please input "y" to continue. Otherwise it will exit![n]y When config manager comes up I hit ESC then this prints out INFO: Getting hardware description... INFO: Rename design_1_wrapper.hdf to system.hdf [INFO] generating Kconfig for project [INFO] menuconfig project *** End of the configuration. *** Execute 'make' to start the build or try 'make help'. [INFO] sourcing bitbake [INFO] generating plnxtool conf [INFO] generating meta-plnx-generated layer [INFO] generating machine configuration [INFO] generating bbappends for project . This may take time ! [INFO] generating u-boot configuration files [INFO] generating kernel configuration files [INFO] generating kconfig for Rootfs Traceback (most recent call last): File "rootfs_config.py", line 315, in <module> parse_args(sys.argv[1:]) File "rootfs_config.py", line 290, in parse_args extract_packages_dot(packages_user) File "rootfs_config.py", line 257, in extract_packages_dot with open(packages_dot,'r') as fp: IOError: [Errno 2] No such file or directory: '/home/iaguilar/Desktop/ZyboLinux/zyboBase/project-spec/meta-user/recipes-core/images/petalinux-image-full.bbappend' ERROR: Failed to generate rootfs /home/iaguilar/Desktop/ZyboLinux/zyboBase/build/misc/rootfs_config/Kconfig.user ERROR: Failed to config project. ERROR: Get hw description Failed!. Do I have to upgrade the bsp to PetaLinux SDK version "2018.3"? Is that why these errors are occurring ?
  2. I am looking for tutorial that guides through the entire flow. Meaning, create a vivado project then create a linux image based on that hardware design. I am trying to figure how to write an application that would access my custom HDL module through Linux. I have already verified that my custom HDL module works through the AXI lite bus interface. I created a bare metal application to test my custom HDL module and everything works as I expect it. So, the next step would be doing the same through a Linux application. Hope that makes sense. Also, I am currently working with vivado within Windows 10 would it make more sense to install vivado on a Linux Box? I have gone through this tutorial: https://github.com/Digilent/Petalinux-Zybo-Z7-20/blob/master/README.md?_ga=2.65706535.861548781.1558477480-254828324.1551742247 Basically, installed Petalinux on VM linux box. Another thing, I had a really hard time installing Petalinux on Ubuntu 18.04.2. I gave up and went to 16.04.4 then seems to work just fine. Not sure if I understand that one. Any guidance would be tremendously appreciated. P.S I am currently using Zybo-Z7 20 board
