Boot Process
############

As described in the :ref:`High Level Architecture` section of the :doc:`/intro`,
the system can boot in 3 different ways. The corresponding boot flow is as
follows:

The booting process of baremetal Zephyr is quite straightforward: Zephyr boots
directly from the reset vector after system reset.

For baremetal Linux, the booting process is as the following diagram:

And the booting process of virtualization solution in this stack is as the
