Upload the firmware to the Arduino board
The board will remember the firmware so you will only have to complete this step once.
- If you haven't already, download and install the Arduino IDE (Windows or Mac instructions)
- Connect the Arduino/Genuino 101 board to your computer's USB port
- Launch the Arduino IDE
- Click on the Tools menu and select Board > Boards Manager...
- Search for "curie" and install the Intel Curie Boards by Intel. Close the Boards Manager once the installation is complete.
- Download the custom Arduino 101 firmware and open it in the Arduino IDE
- Select Arduino/Genuino 101 under the Tools > Board menu
- Select the correct serial port under the Tools > Port menu.
On Mac, it's something like /dev/cu.usbmodemXXXXX.
On Windows, it's probably the highest-numbered COM port.
(Or unplug the Arduino, check the menu, and then replug your Arduino and see what new port appears.)
- Click the upload button
