Programming

Use the Arduino Software Development Environment to create programs, called
sketches, for the Intel
1. Connect a power supply.
2. Connect the board's USB client port to a computer.
3. Upload the sketch using the IDE interface.
The sketch runs on the Intel
in the board's firmware using the Arduino I/O adapter. For complete details on
programming your board, see the Intel
When the board boots up, two scenarios are possible:
• If a sketch is present in persistent storage, it is executed.
• If no sketch present, the board waits for upload commands from the IDE.
If a sketch is executing, you can upload from the IDE without having to press the reset
button on the board. The sketch is stopped; the IDE waits for the upload state, and
then starts the newly uploaded sketch.
Pressing the reset button on the board restarts a sketch if it is executing and resets any
attached shields.

Automatic (Software) Reset

Rather than requiring a physical press of the reset button before an upload, the Intel
Galileo Board is designed in a way that allows it to be reset by software running on a
connected computer. USB CDC-ACM control signals are used to transition the board
from run-time to bootloader mode. The Arduino software uses this capability to allow
you to upload code by simply pressing the upload button in the Arduino environment.
