Root Cause

In CentOS-7.x if you set LD_LIBRARY_PATH variable (example export LD_LIBRARY_PATH=/lib64:/usr/lib64:/usr/local/lib64) causes the petalinux-config menu to crash with segmentation fault. In Yocto, if you want to use any build host binaries or libraries you need to unset LD_LIBRARY_PATH. Once it goes to segmentation fault terminal, follow these steps to kill the seg fault terminal.

1. Type reset and enter key. Now terminal will be blank.
2. Press Ctrl+J same time.

   Now you should have a working terminal.

Solution

To work around this issue, follow these steps.

1. Unset the LD_LIBRARY_PATH by running below command.

   $ unset LD_LIBRARY_PATH

2. Source the PetaLinux tools.

   $ source /opt/xilinx/petalinux/petalinux-v2020.1/settings.sh

3. Run menu config.

   $ petalinux-config
