    or

    $ chmod 755 <installation-directory-of-your-choice>

    Also make sure ‘petalinux-v2018.2-final-installer.run’ is executable. For this run command

    $ chmod +x ./petalinux-v2018.2-final-installer.run

$ ./petalinux-v2018.2-final-installer.run
  • Without any options, the PetaLinux Tools are installed into the current working directory.
Alternatively, Here is the Steps for installing Petalinux on your specified directory:

For example: To install PetaLinux Tools under /opt/pkg/petalinux:

$ mkdir –p /opt/pkg/petalinux

$ ./petalinux-v2018.2-final-installer.run /opt/pkg/petalinux

This installs the PetaLinux Tools into /opt/pkg/petalinux directory.

You will see a warning “You haven’t specified the installation location” if you have not specified the installation directory and you have to press ‘y’ and enter to proceed the installation further. In this case the PetaLinux will be installed in you current working directory.
  • Now you wait for the installation to complete. This will take around 30 minutes depending on your system performance. After installation you there are few steps to make bash shell recognize petalinux commands.
