  1. Establish a serial connection with your device

  2. Download the firmware

  3. Program the firmware

1. Establish a serial connection with your device

Open a serial connection with the device. You can use any serial terminal program such as Tera Term, Minicom, CoolTerm, or HyperTerminal.

PuTTY terminal program is not recommended due to an incompatibility with the USB/serial driver.

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

2. Download the firmware

Download the firmware images from the following location: https://ftp1.digi.com/support/digiembeddedyocto/4.0/r7/images/ccimx8x-sbc-pro/ccimx8x-sbc-pro-installer.zip

3. Program the firmware

Digi recommends you use the Universal Update Utility (UUU) through a USB connection to your development PC to program the images.

  1. Decompress the zip file in a directory of your choice.

  1. Download the latest Universal Update Utility (UUU), a software tool from NXP.

    UUU version should be v1.5.11 or higher.

  2. Place the uuu executable in a directory in your PATH, such as /usr/bin.

  3. Install udev rules to allow any user to run uuu to access the USB port:

    $ sudo sh -c "uuu -udev >> /etc/udev/rules.d/70-uuu.rules"
$ sudo udevadm control --reload

  1. Connect a USB type-C cable to your development PC and the other end to the target USB type-C connector.

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

    Information in the console log may vary.

  3. On the target, in U-Boot, execute the following command:

    => fastboot 1

  4. On your development PC, change to the directory where you extracted the ZIP file:

    $ cd <zip-folder>

  5. Program the image files:

    $ ./install_linux_fw_uuu.sh

  6. Once the firmware is installed, the device boots automatically. The default username is root with no password.

While the recommended boot method is eMMC, you can also boot the image from a microSD card using the *.sdcard image file on the downloaded ZIP file. See Boot from microSD card for instructions on programming a microSD card and booting from it.

You must use a microSD with a minimum capacity of 8 GB.
