.. tab-set::

   .. tab-item:: Build NuttX: Single Core

        * Build NuttX for a Single Core of Arm Cortex-A53, first configure NuttX for Single Core as shown below:

        .. code-block:: c
            
                $ ./tools/configure.sh -l qemu-armv8a:nsh
                No configuration change.


        * Build NuttX

        .. code-block:: c
            
                $ make
                LD: nuttx
                CP: nuttx.hex
                CP: nuttx.bin


        * Dump the disassembly to nuttx.S:

        .. code-block:: c
            
                aarch64-none-elf-objdump \
                  -t -S --demangle --line-numbers --wide \
                  nuttx \
                  >nuttx.S \
                  2>&1
