You will need to download the Ubuntu 18.04 rootfs files from this link:
The two files you will need from this link are located in the
You will need to extract the .bz2 file using 7zip on Windows or
bzip2 -d <filename> on Linux.
UUU is a tool used for flashing i.MX8 boards. You can download UUU for Windows or Linux using the link below:
In order to flash the NavQ using UUU, you'll have to change the DIP switches to the following configuration:
Power the board over USB-C as normal. You'll also want to connect to the USB-C/UART adapter and pull up a serial console (with baud rate 115200) to watch the serial output while flashing in case there are any errors.
(NOTE: This has only been tested on Windows 10)
Open CMD on Windows as administrator and change your directory to where you stored the uuu.exe, boot, and ubuntu rootfs files that you downloaded at the beginning of this guide. Then, plug the NavQ in with the correct DIP switch configuration and run the following command in the CMD:
.\uuu.exe -b emmc_all imx-boot-imx8mmevk-ds.bin-flash_evk imx-image-multimedia-ubumtu-imx8mmevk-20200611102300.rootfs.sdcard
Your eMMC should now be flashed with the Ubuntu 18.04 rootfs. After this step, it still won't boot, so there are a few more steps to get it to boot.
(NOTE: You must have an SD card that you can boot from or you can't perform these steps.)
Boot from the SD card and run the following commands to mount the eMMC boot partition:
cd /mnt/mkdir bootsudo mount /dev/mmcblk2p1 /mnt/boot
Your eMMC boot partition should now be mounted. Next, you'll need to connect your NavQ over ethernet to your computer or router. Use an FTP client (I used FileZilla) to FTP into the NavQ, and then place the following file in /mnt/boot:
This is a Device Tree Blob (dtb) file that tells Linux what the device tree looks like. (WiFi does not work with this .dtb, a new one with WiFi working will be provided soon). Once you've successfully copied over the .dtb file, you'll need to unmount the boot partition:
sudo umount /dev/mmcblk2p1
Now you can change the DIP switches to boot from eMMC and reboot by running
reboot in the serial console.
Once the NavQ starts booting from the eMMC, you'll want to press enter repeatedly until you get to the U-Boot console prompt. Once you're in the U-Boot prompt, you'll need to run the following commands:
setenv fdt_file imx8mm-navq.dtbsaveenvboot
Your NavQ should then boot into the Ubuntu rootfs.
