2. Connect the USB cable to the USB Client Port (closest to the Ethernet) and to a

PC. Wait for Windows to begin its driver installation process. After a few moments,

the process will fail.

3. Click on the Start Menu, and open up the Control Panel. While in the Control

Panel, navigate to System. Next, click on System. Once the System window is

up, open the Device Manager.

4. Look under Ports (COM & LPT). You should see an open port named Gadget

Serial V2.4. If you do not see this open port, follow steps a-c in the Note below.

5. Right-click on the Gadget Serial V2.4 port and choose the Update Driver

Software option.

6. Choose the Browse my computer for Driver software option.

7. Navigate to the hardware/arduino/x86/tools directory. This allows the proper

driver file linux-cdc-acm.inf to be installed.

8. Once the driver is successfully installed, Device Manager will show a

Galileo (COMx) device under Ports (COM & LPT). Note the COMx port number

as it will be needed in the IDE later. The example below shows COM5.

Note: You may find Gadget Serial 2.4 under Other devices in Device Manager. If

this is the case, do the following:

a. In Windows Explorer, go to C:\Windows\System32\drivers and look for

usbser.sys. If it is present, you can skip these steps. If it is missing,

copy usbser.sys from the archive location identified below:

Windows 7:

C:\Windows\System32\DriverStore\FileRepository\mdmcpq.inf_amd6

4_neutral_fbc4a14a6a13d0c8\usbser.sys (archive file)

Windows 8:

C:\Windows\System32\DriverStore\FileRepository\mdmcpq.inf_amd6

4_d9e0b9c4fe044b4d\usbser.sys (archive file)

b. In Windows Explorer, copy to: C:\Windows\System32\drivers

You may need to provide Administrator Permission to complete the copy.

c. Once usbser.sys is copied, continue with step 5 above.

Linux:

1. If not done already, connect the 5V power cable to the board and to a power

outlet. Wait for the board to boot.

Note: Always connect the 5V power before the USB connection.

2. Connect the USB cable to the USB Client Port (closest to the Ethernet) and to a

PC.

3. Check that ACM port is available by typing in the terminal ls /dev/ttyACM*

Intel®Galileo Board Getting Started Guide

6 Order Number: 329685-006US

Note: If the /dev/ttyACM0 port is not present, follow the procedure below:

a. Create a file etc/udev/rules.d/50-arduino.rules and add the following:

KERNEL=="ttyACM[0-9]*", MODE="0666"

b. Restart the udev with the following command: sudo service udev restart

If you are using a virtual machine (VM), you may need to reboot Linux within

the VM.

4. Launch the IDE.

The first time you compile and install a sketch, the Galileo software will be

installed automatically. This requires appropriate file and directory access

permissions. You may be required to run the IDE as root or using sudo arduino

depending on your Linux distribution.

5. Select your board via Tools > Board > Intel®Galileo

6. Select the port Tools > Serial Port > /dev/ttyAMC0

Note: If the serial ttyACM0 is not available, make sure you have the proper rights to

access the ports. If the serial port is disabled on your IDE, exit the IDE and

execute again using the command: sudo arduino

OS X:

The Galileo board is supported by the OS X built-in USB drivers, however, the board

has to boot for it to show up because the port is driven by software on the board.

1. If not done already, connect the 5V power cable to the board and to a power

outlet. Wait for the board to boot.

Note: Always connect the 5V power before the USB connection.

2. Connect the USB cable to the USB Client Port (closest to the Ethernet) and to your

Mac. Check the System Profiler > USB setting to be sure that Gadget Serial is

selected. If you are installing a new version of the IDE, you may need to re-select

this setting.

3. In the Arduino IDE, the correct serial port shows in the Tools > Serial Port menu

as /dev/cu.usbmodemnnnnn where nnnnn is a number such as fd121.

Do not select the /dev/tty port.

5. Launch the Arduino IDE application

Windows: In the folder arduino-1.5.3, double-click arduino.exe

Linux: In the folder arduino-1.5.3, launch Arduino by executing ./arduino

Note: You may see an error stating Java is not present. If you are using Ubuntu, run

Click Yes if it is connected. If no cable is plugged in, exit the upgrade process by

selecting No, connect the power, and restart this process.

9. The board can be upgraded to newer software or downgraded to older software.

The next message displays the current software version that is on the board and

the software version that you are trying to flash onto the board. Select Yes to

either Upgrade/Downgrade or flash the same software again.

10. The upgrade progress takes about 6 minutes and is displayed in several popup

messages. During the upgrade process, you will not have access to the IDE.

Note: The power and USB cables must stay connected during the upgrade process.

11. When the upgrade completes, a message is displayed stating Target Firmware

upgraded successfully. Click OK to close the message.

Note: On OS X, you must reboot the IDE before continuing.

If you want to flash a different firmware version that is not contained in the IDE,

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

The downloaded capsule should be copied to the following locations, depending upon

your operating system. Make sure that there is only one *.cap file in the location

below. If you are downloading a new file, rename the previous *.cap to some other

extension.

•Windows: Arduino-1.5.3/hardware/tools/x86/bin/

•Linux: Arduino-1.5.3/hardware/tools/

•OS X: Arduino.app/Contents/Resources/Java/hardware/tools/x86/bin/

Note: If you see a failure at any stage of the upgrade, refer to the Release Notes for

known issues and possible workarounds.

7. Open the blink example

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

Follow these steps to boot your board from an SD card. This setup also allows you to

save your sketch to the Galileo board, so it will be able to repeat sketches after board

power-down. (These steps create a persistent /sketch folder and rootfs.)

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.

Required files are in the LINUX_IMAGE_FOR_SD_Intel_Galileo_v1.0.0.7z zip file

(download link in Section 2).

Note: Your SD card must meet the following requirements:

SD card must be formatted as FAT or FAT32.

Intel®Galileo Board Getting Started Guide

Order Number: 329685-006US 9

SD card size must be 32GB (or smaller) and SDHC format.

SDXC format is not supported.

1. Copy all files and directories from the zip file to your SD card.

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

necessary files and structure. Be 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.

Troubleshooting tips:

To boot from SD/USB, the grub instance embedded in the SPI flash is hardcoded to

search for a boot/grub/grub.conf file in partition 1 on the SD/USB card. This is

compatible with the factory formatting of most SD/USB devices. By default, the UEFI

firmware does not try to boot from SD or USB, it is handled by grub.

If you use an SD or USB device that has been reformatted after manufacturing, you

might experience problems booting from it. First, try to boot with a different memory

device and see if the problem goes away. If you isolate the problem to a specific SD

card, you can restore the factory formatting using this tool from the SD association:

https://www.sdcard.org/downloads/formatter_4/

It is not recommended to use normal operating system tools to format flash memory

devices.

12. Serial cable (optional)

You can access the embedded Linux using a serial cable connected to the 3.5 mm

audiojack port on the Galileo board. Be sure that the cable is RS-232 format and not

TTL format (details here: https://www.sparkfun.com/tutorials/215).

For a 3 pin audio jack, the connections are shown below:

•Pin 1 Sleeve = Ground

•Pin 2 Ring = RXD (input)

•Pin 3 Tip = TXD (output)

13. Manually update your board firmware (optional)

Note: This method has been replaced by functionality in the IDE.

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.

The Intel®Quark™ BSP software provides a mechanism to update SPI flash contents

based on EDKII capsules. These capsules contain a BIOS, bootloader, and compressed

Linux run-time system sufficent to boot a Quark-based board, such as the Intel®

Galileo board. For details, see the Intel®Quark™ SoC X1000 BSP Build Guide

[https://communities.intel.com/docs/DOC-21882]

14. Troubleshooting Tips

Problems with COM ports

There is a known issue with Windows that it creates a new COM port every time a

device is connected. In cases when there are many unused COM ports, the Galileo

board may stop working and/or the IDE may return the error below:

/dev/ttyS24: No such file or directory

One workaround is to delete all unused and hidden COM ports, including the drivers.

1. Disconnect the USB cable from the Galileo board.

2. On your Windows host machine, open a command prompt window and run it as

administrator as follows:

Click the Start Menu, and type Command. Right-click the command prompt icon

and select Run as administrator.

3. In the command prompt window, type the commands below:

set devmgr_show_nonpresent_devices=1 to display hidden devices

start devmgmt.msc to start the device manager

4. In the Device Manager window, select View > Show Hidden Devices

Unused COM ports will be grayed-out.
