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.

    with open(packages_dot,'r') as fp:

 Do I have to upgrade the bsp to PetaLinux SDK version "2018.3"? Is that why these errors are occurring ?

The BSP for zybo-z7-20 will work properly only with petalinux 2017.4. Upgrade for the BSP is estimated to take place after petalinux 2019.2 is released Q1 next year.

Welcome to the club.  I have found version sensitivity to be a big problem with Petalinux in general.  Often an old bsp will push you back several versions of Petalinux.  Then Petalinux itself is very sensitive to the OS of the host development system so you might have to go back a couple of Linux version on your workstation.  This is due to the enormous number of dependencies involved with the Petalinux, Yocto, Bitbake, scheme.

In one case, I figured out how to make my own Petalinux 2019.1 version of a BSP. That got me going after a week of frustration.
