Decompress the zip file in a directory of your choice.
-
Download the latest Universal Update Utility (UUU) tool, a software tool from NXP.
-
Place the uuu executable in a directory in your PATH, such as
/usr/bin
. -
Install
udev
rules to allow any user to run the uuu for accessing the USB port:$ sudo sh -c "uuu -udev >> /etc/udev/rules.d/99-uuu.rules" $ sudo udevadm control --reload-rules
-
Connect a USB type-C cable to your development PC and the other end to the target USB type-C connector.
-
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:

On your development PC, change to the directory where you extracted the ZIP file:
$ cd <zip-folder>
-
To program the WebKit image, run:
$ ./install_linux_fw_uuu.sh -i dey-image-webkit
-
Once the firmware is installed, the device boots automatically. The default username is root with no password.
