The Intel® Edison compute module is a modular, small and powerful system on a chip (SoC) that includes a CPU, MCU, memory, storage and dual-band Wi-Fi and Bluetooth. The module can be mounted onto a system of expansion boards, enabling quick adoption and prototyping for the consumer and light industrial IoT applications.
Flashing the image
Before you begin flashing, you will need the following items in addition to your Edison board:
- Micro-USB cable
To flash Android Things onto your Edison, download the latest preview image and follow these steps:
Step 1: Install Fastboot
If this is your first time installing Android Things on the Edison, you need to upgrade the bootloader to be Fastboot capable. Follow the Intel Getting Started Guide to perform the required one-time setup steps on your board:
Step 2: Connect the Hardware
Connect the board to your host computer:
For Arduino Expansion Board:
- Ensure switch SW1 is in the position towards the micro USB ports.
- Press the FW button and keep it pressed.
- Connect a USB cable to J16.
- Release the FW button.
For Sparkfun Block:
- Connect a USB cable to the OTG connector.
Step 3: Flash Android Things
Once you have loaded the proper bootloader on your device, use the following steps to flash the Android image:
Update the Android SDK Platform Tools to version 25.0.3 or later from the SDK Manager.
- Verify that the
fastbootbinary is installed in the
platform-tools/directory of your Android SDK.
- After you have the fastboot tool, add it to your
- Verify that the
Open a command line terminal and navigate to the unzipped image directory.
If your device is not already in Fastboot mode, use the adb tool to activate it:
$ adb reboot bootloader
Verify that the device has booted into Fastboot mode by executing the following:
$ fastboot devices 1b2f21d4e1fe0129 fastboot
flash-all.shscript. This script installs the necessary bootloader, baseband firmware(s), and operating system. (On Windows systems, use
To verify that Android is running on the device, discover it using the adb tool:
$ adb wait-for-device ... $ adb devices List of devices attached 1b2f21d4e1fe0129 device
After flashing your board, it is strongly recommended to connect it to the internet. This allows your device to deliver crash reports and receive updates.
To connect your board to Wi-Fi, first access a shell prompt on the device. You can use either of the following methods:
- Open a shell
over adb with the
- Connect to the serial console.
Once you can access a shell prompt, follow these steps:
Send an intent to the Wi-Fi service that includes the SSID and passcode of your local network. Your board must support the network protocol and frequency band of the wireless network in order to establish a connection.
$ am startservice \ -n com.google.wifisetup/.WifiSetupService \ -a WifiSetupService.Connect \ -e ssid <Network_SSID> \ -e passphrase <Network_Passcode>
Verify that the connection was successful through
$ logcat -d | grep Wifi ... V WifiWatcher: Network state changed to CONNECTED V WifiWatcher: SSID changed: ... I WifiConfigurator: Successfully connected to ...
Test that you can access a remote IP address:
$ ping 220.127.116.11 PING 18.104.22.168 (22.214.171.124) 56(84) bytes of data. 64 bytes from 126.96.36.199: icmp_seq=1 ttl=57 time=6.67 ms 64 bytes from 188.8.131.52: icmp_seq=2 ttl=57 time=55.5 ms 64 bytes from 184.108.40.206: icmp_seq=3 ttl=57 time=23.0 ms 64 bytes from 220.127.116.11: icmp_seq=4 ttl=57 time=245 ms
Check that the date and time are set correctly on the device:
If you want to clear all of the saved networks on the board:
$ am startservice \ -n com.google.wifisetup/.WifiSetupService \ -a WifiSetupService.Reset
Serial debug console
The serial console is a helpful tool for debugging your board and reviewing
system log information. The console is the default output location for kernel
log messages (i.e.
dmesg), and it also provides access to a full shell prompt
that you can use to access commands such as logcat.
This is helpful if you are unable to access ADB on your board through other
means and have not yet enabled a network connection.
To access the serial console, connect a micro USB cable to the board as follows:
For Arduino Breakout: Connect to J3.
For Sparkfun Block: Connect to CONSOLE.
Open a connection to the USB serial device on your development computer using a terminal program, such as PuTTY (Windows), Serial (Mac OS), or Minicom (Linux). The serial port parameters for the console are as follows:
- Baud Rate: 115200
- Data Bits: 8
- Parity: None
- Stop Bits: 1
