5Preparing the Boot Device
6-------------------------
7
8Prepare a USB flash drive to boot the Zephyr application image on
9a board.
10
11#. Format the USB flash drive as FAT32.
12
13   On Windows, open ``File Explorer``, and right-click on the USB flash drive.
14   Select ``Format...``. Make sure in ``File System``, ``FAT32`` is selected.
15   Click on the ``Format`` button and wait for it to finish.
16
17   On Linux, graphical utilities such as ``gparted`` can be used to format
18   the USB flash drive as FAT32. Alternatively, under terminal, find out
19   the corresponding device node for the USB flash drive (for example,
20   ``/dev/sdd``). Execute the following command:
21
22   .. code-block:: console
23
24      $ mkfs.vfat -F 32 <device-node>
25
26   .. important::
27      Make sure the device node is the actual device node for
28      the USB flash drive. Or else you may erase other storage devices
29      on your system, and will render the system unusable afterwards.
30
31#. Copy the Zephyr EFI image file :file:`zephyr/zephyr.efi` to the USB drive.
32
33Booting Zephyr on a board
34-------------------------
35
36Boot the board to the EFI shell with USB flash drive connected.
37
38#. Insert the prepared boot device (USB flash drive) into the board.
39
40#. Connect the board to the host system using the serial cable and
41   configure your host system to watch for serial data. See board's
42   website for more information.
43
44   .. note::
45      Use a baud rate of 115200.
46
47#. Power on the board.
48
49#. When the following output appears, press :kbd:`F7`:
50
51   .. code-block:: console
52
53      Press <DEL> or <ESC> to enter setup.
54
55#. From the menu that appears, select the menu entry that describes
56   that particular EFI shell.
57
58#. From the EFI shell select Zephyr EFI image to boot.
59
60   .. code-block:: console
61
62      Shell> fs0:zephyr.efi
63
64#. When the boot process completes, you have finished booting the
65   Zephyr application image.
