The HoverGames images come as a .bz2 compressed archive. To decompress this image, you'll need to use a program like 7zip on Windows, use the bunzip2 command on Linux, or double click the archive on Mac.
NXP has a tool for flashing i.MX hardware called UUU (Universal Update Utility). You can download UUU from here:
It is recommended to download the "Latest Release", not the "Pre-Release" at the top of the page.
If you're on Windows, you'll want to download the uuu.exe file, and if you're on Linux, you'll want to download the uuu file.
You must agree to all of the applicable licenses and agreements at the following link before downloading the Linux software. It is hosted here:
NOTE: This file is only needed for flashing with UUU to the eMMC/SD Card. If you want to flash your SD Card with dd or Win32DiskImager, this file is not needed.
Flip the DIP switches on your NavQ to put it into USB flashing mode (boot from USB in the image below). Here is an image that shows how to do so:
Once you're done flashing, you can use this image to select the boot mode: eMMC or SD card.
Connect your NavQ using the included USB-C cable to your computer. You should recieve a message on your computer that it has been connected. To make sure the NavQ is connected, you can run the UUU program with the -lsusb flag and you should see an output similar to this:
You can flash both the SD card and the eMMC using this tool. The keyword for flashing the SD card is sd_all, while the keyword for flashing the eMMC is emmc_all. The command to flash your board is outlined below:
There are advantages and disadvantages to each storage medium. eMMC is faster, but is locked to 16GB size and is non-removable. SD cards can be of any size you like and are removable, but they are quite a bit slower.
After a few moments, your board should be flashed. Unplug your NavQ from power, reset the DIP switches to the desired boot device, and you're good to go!
To flash the image, you'll need to use dd on Linux/Mac or Win32DiskImager on Windows.
Replace the X in "/dev/sdX" with the letter of your SD card in linux. You can use a program like "GParted" or "Disks" to find the letter of your SD card.
Replace the X in "/dev/rdiskX" with the number of your SD card in Mac. You can use diskutil list to find the number of your SD Card.
Download Win32DiskImager:
Currently the HoverGames-Demo Linux image is packaged as a .img file. In future releases, it may be packaged as a .wic.bz2 file. If it is packaged as a .wic.bz2 file, you'll want to extract the .bz2 file before flashing using Win32DiskImager.
Open the program and select your SD card. Choose the .wic OR .img file, then click "Write".
