1. Power the kit off by disconnecting the USB Type C cable from the development host.

2. Set the target boot mode to the USB serial downloader mode by setting the boot switches as follows:

   • SW2.1 - 1

   • SW2.2 - 0

3. Power the kit on by connecting the USB Type C cable to the development host. Use the kit port labeled USB1.

4. Check that the new USB device has appeared on your development host:

   Code Block
   [psl@i7 ~]$ lsusb | grep -i nxp Bus 001 Device 025: ID 1fc9:0146 NXP Semiconductors

5. On the host, go to the Yocto images directory:

   Code Block
   [psl@i7 ~]$ cd ~/5-15-5-DESKTOP/builddir/tmp/deploy/images/imx8mpnavq [psl@i7 imx8mmnavq]$ ls -1 ... imx-boot-imx8mpnavq-sd.bin-flash_evk imx-image-desktop-ros-imx8mpnavq.wic.bz2zst uuu ...

   • The images above are:

   • imx-boot-imx8mpnavq-sd.bin-flash_evk - U-Boot-ATF-OPTEE boot image;

   • imx-image-desktop-ros-imx8mpnavq.wic.bz2zst - Ubuntu 20 root filesystem;

   • uuu - pre-built image of the uuu utility (you could also use pre-built uuu image from https://github.com/NXPmicro/mfgtools/releases/latest, or build it from sources https://github.com/NXPmicro/mfgtools/tree/master);

6. Unpack the compressed image of the root filesystem:

   Code Block
   [psl@i7 imx8mmnavq]$ bzip2zstd -d imx-image-desktop-ros-imx8mpnavq.wic.bz2zst ...

7. Launch the uuu tool with appropriate script as a parameter for installing the bootable Linux image:

   Code Block
   [psl@i7 imx8mmnavq]$ sudo ./uuu -v -b sd_all imx-boot-imx8mpnavq-sd.bin-flash_evk imx-image-desktop-ros-imx8mpnavq.wic uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.3.82-0-g9c56e46 Wait for Known USB Device Appear...

8. The uuu tool will proceed to install the Production Yocto image to the storage device (SD card) on the target board:

   Code Block
   uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.3.74-2-g302da91 Success 1 Failure 0 ... 1:3 7/ 7 [Done ] FB: Done

9. When uuu has finished, the bootable Linux image has been installed to the on-module storage. Given proper setting of the boot switches, next power-on will boot the target board from the SD storage device.
