11. Booting your board from an SD card (mandatory for WiFi)

Note: If you want to use WiFi, you must follow these steps. The WiFi driver is not present in

the Linux image in SPI flash because it is too large. The Linux SD image also includes

ALSA, V4L2, python, SSH, node.js, and openCV.

To boot your board from an SD card, follow these steps. This also enables persistent

rootfs and persistent /sketch folder.

Required files are in the meta-clanton zip file (download link in Section 2).

1. Copy all files/directories from the meta-clanton zip file to the SD card.

You do not need to create a directory on the SD card. The zipfile contains all the

necessary files and structure, make sure it is extracted at the top level of the SD

card. See the screenshot below for a sample view.

2. Insert the SD card, then power on the board.

Note: The first time you boot the board may take several minutes. This is expected behavior

due to the SSH component creating cryptographic keys on the first boot.

12. Manually update your board firmware (optional)

Note: This method has been replaced by functionality in the IDE. It is provided for reference

only.

You must update the firmware the first time you use the board to ensure the firmware

on the board is in sync with the IDE.

These steps assume you have a microSD card inserted into the slot on the board,

which contains the release-specific sysimage_nnnn.cap file and the CapsuleApp.efi

file.

Caution: The CapsuleApp.efi and the *.cap file are a matched pair and must be used

together. When a new *.cap file is released, you must use the corresponding

CapsuleApp.efi to install it.

Perform the steps below:

1. Download the SPI flash image capsule files as described in Section 2.

2. Copy CapsuleApp.efi and sysimage_nnnnn.cap to a microSD card and insert it

into the slot on the board .

3. Connect the serial cable between the computer and the Galileo board. Set up a

serial console session (for example, PuTTY) and connect to the Galileo board’s

COM port at 115200 baud rate.

4. Configure the serial console session to recognize special characters. For example,

if you are using PuTTY, you must explicitly enable special characters. In the PuTTY

Configuration options, go to the Terminal > Keyboard category and set the

Function keys and Keypad option to SCO.

5. Power on the board. A GNU GRUB boot loader menu is displayed (below).
