NXP Pico i.MX6UL

The Pico SoM is a 36x40mm, high performance platform that is highly optimized for Internet of Things applications. It is pin-compatible with the Intel® Edison for sensors and low-speed I/O, but also adds additional expansion possibilities for multimedia and connectivity, giving you cutting edge technology that can easily be expanded and implemented for IoT designs.

See Pico i.MX6UL I/O for more details on the Peripheral I/O signals on this board.

Flashing the image

Before you begin flashing, you will need the following items in addition to your Pico board:

To flash Android Things onto your Pico, download the latest preview image, unzip it on your host computer, and follow these steps:

  1. Update the Android SDK Platform Tools to version 25.0.3 or later from the SDK Manager.

    • Verify that the fastboot binary is installed in the platform-tools/ directory of your Android SDK.
    • After you have the fastboot tool, add it to your PATH environment variable.
  2. Connect the board to your host computer:

    ""

    1. Connect a USB-C cable to the USB OTG connector.
    2. Connect a 5V power adapter to the power input connector.
  3. Open a command line terminal and verify that the device has booted into fastboot mode by executing the following:

    $ fastboot devices
    1b2f21d4e1fe0129    fastboot
    
  4. Ensure that the bootloader is unlocked.

    $ fastboot oem unlock
    
  5. Navigate to the unzipped image directory.

  6. Execute the following fastboot commands to install the operating system image:

    $ fastboot \
        flash bootloader u-boot.imx \
        reboot bootloader
    
    $ fastboot \
        flash gpt partition-table.img \
        reboot bootloader
    
    $ fastboot \
        flash boot_a     boot.img \
        flash boot_b     boot.img \
        flash system_a   system.img \
        flash system_b   system.img \
        flash userdata   userdata.img \
        set_active _a
    
    $ fastboot \
        flash gapps_a gapps.img \
        flash gapps_b gapps.img
    
    $ fastboot \
        flash oem_a oem.img \
        flash oem_b oem.img
    
  7. Reboot the device into Android Things:

    $ fastboot reboot
    
  8. To verify that Android is running on the device, execute the following:

    $ adb devices
    List of devices attached
    4560736843791520041    device
    

Connecting Wi-Fi

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.

Before connecting your board to a Wi-Fi network, attach an external IPEX or u.FL Wi-Fi antenna to your board as shown:

""

To connect your board to Wi-Fi using adb:

  1. Send an intent to the Wi-Fi service that includes the SSID and passcode of your local network:

    $ adb shell am startservice \
        -n com.google.wifisetup/.WifiSetupService \
        -a WifiSetupService.Connect \
        -e ssid <Network_SSID> \
        -e passphrase <Network_Passcode>
    
  2. Verify that the connection was successful through logcat:

    $ adb logcat -d | grep Wifi
    ...
    V WifiWatcher: Network state changed to CONNECTED
    V WifiWatcher: SSID changed: ...
    I WifiConfigurator: Successfully connected to ...
    
  3. Test that you can access a remote IP address:

    $ adb shell ping 8.8.8.8
    PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
    64 bytes from 8.8.8.8: icmp_seq=1 ttl=57 time=6.67 ms
    64 bytes from 8.8.8.8: icmp_seq=2 ttl=57 time=55.5 ms
    64 bytes from 8.8.8.8: icmp_seq=3 ttl=57 time=23.0 ms
    64 bytes from 8.8.8.8: icmp_seq=4 ttl=57 time=245 ms
    

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 USB to TTL Serial Cable to the debug interface as shown below.

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:
