Software Download/Setup
• "Bigger" Linux Image
• Download the Arduino IDE for Galileo
– https://communities.intel.com/docs/DOC-22226
Software Download/Setup
• Unzip SDCard.1.0.4.tar
– image-full-galileo folder is generated
Software Download/Setup
• Copy all files/folder under image-full-galileo into
your micro SD card
• Your SD directory structure should look like:
Running "Bigger" Linux Image
(Option 1)
•
•
•
•
•
•
Unplug the USB connector of Galileo
Remove the Galileo power
Plug in the µSD card.
Then power it back up.
Plug in the USB connector
The first boot may take a little longer than
average.
Running "Bigger" Linux Image
(Option 2)
•
•
•
•
•
•
Unplug the USB connector of Galileo
Remove the Galileo power
Plug in the µSD card.
Then power it back up.
Plug in the RS232-USB connector
The first boot may take a little longer than
average.
• You can use the terminal to verify that the bigger
image is working. Try running Python, for
example.
Running "Bigger" Linux Image
• RS232 to USB
– Connect (RS232  Galileo)
• Black Wire  GND
• White Wire  TXO
• Green Wire  RXI

# Set pin 13 to be used as an output GPIO pin.
print 'Setting up pin %d' % pin
gpio.pinMode(pin, gpio.OUTPUT)
print 'Blinking pin %d now...' % pin
Python
try:
while(True):
# Write a state to the pin. ON or OFF.
gpio.digitalWrite(pin, state)
# Toggle the state.
state = gpio.LOW if state == gpio.HIGH else gpio.HIGH
# Sleep for a while.
time.sleep(0.5)
# When you get tired of seeing the LED blinking kill the loop with Ctrl-C.
except KeyboardInterrupt:
# Leave the LED turned off.
print '\nCleaning up...'
gpio.digitalWrite(pin, gpio.LOW)
# Do a general cleanup. Calling this function is not mandatory.
gpio.cleanup()
