        * Download the ARM Toolchain for Linux x64 and WSL from the below link:
        
        .. code-block:: c

                https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/binrel/gcc-arm-11.2-2022.02-x86_64-aarch64-none-elf.tar.xz


        * Add the downloaded Arm Toolchain to the PATH as shown below:
        
        .. code-block:: c

                $ mkdir -p /home/test/toolchains
                $ export PATH="$PATH:$HOME/toolchains/gcc-arm-11.2-2022.02-x86_64-aarch64-none-elf/bin"


        * Check the Arm Toolchain using below command:
        
        .. code-block:: c

                $ aarch64-none-elf-gcc -v
                Using built-in specs.
