The ConnectCore 6 SBC device ships without an operating system loaded. Only U-Boot is programmed in the device. The following instructions demonstrate how to install Android in your device.

1. Establish a serial connection with your device

Before programming the firmware, open a serial connection with your device. You can use any serial terminal, such as Tera Term, PuTTY, Minicom, CoolTerm, or HyperTerminal.

Open a serial connection with the following settings:

Parameter Value

Port

Serial port where the device is connected

Baud rate

115200

Data bits

8

Parity

None

Stop bits

1

Flow control

None

2. Program the firmware

Once you have established a serial connection with your device, you can start the firmware update process.

  1. Download the firmware images from ftp://ftp1.digi.com/support/android/8.0/r1/82004313_A.zip.

  2. Decompress 82004313_A.zip.

  3. Place the decompressed files in the root of a FAT formatted microSD card and insert it in the microSD socket of your device.

  4. Reset the device by pressing the Reset button on the board, and immediately press a key in the serial terminal to stop the auto-boot process. The U-Boot bootloader prompt displays:

  1. Install the firmware into the internal eMMC, executing the following commands:

    => fatload mmc 1 $loadaddr install_android_fw_sd.scr
    => source $loadaddr
    The first Android boot takes several minutes due to the system deployment.
  2. Verify Android has started.

    Work with your device as with any standard Android device. Use the All Apps button to navigate and explore the applications or configure your device in the Settings application.


During installation, error messages appear when the installation process attempts to override MAC addresses. These messages are expected.
