UUU - Universal Update Utility

The Universal Update Utility is used to program your board. It repaces NXP’s “MFG-Tool”. We actually use uuu to flash our TX8M module series. For everything below (TX6 and TXUL series) please continue to use MFG-Tool.

Getting uuu

Get the latest stable file uuu (for Linux) or uuu.exe (for Windows) from NXP’s official repository: https://github.com/NXPmicro/mfgtools/releases

udev Rules

Note

This is just relevant for LINUX users.

There’s no need to call uuu as sudo. Just update your udev rules as follows.

Put above udev run into /etc/udev/rules.d/70-uuu.rules and update udev-rules.

This can be achieved running the following two commands:

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

Usage

UUU uses the android fastboot protocol. The usual way to flash our modules is to start the mfg-uboot, write the default u-boot into eMMC and then flash the Boot-partition and Rootfs as filesystem image.

Tip

You can use pre-compiled images and scripts from our Customer Area or your own Yocto built images.

Running uuu

On Windows 10 or Linux uuu will work fine. For Windows 7 see Running UUU on Windows 7.

1. Put the bootmode jumper in place (for Help see Enabling USB-Bootmode) and connect your module via OTG-programming port of the baseboard.
2. Get terminal access. If you need help for this see TTL Converter Terminal Connection.

2. Open a command line inside the folder where uuu is and run the following command to use the before created script:

uuu -v <script-file>

Tip

Inside your terminal you should now see progress and information while uuu is programming your module.

UUU with Custom Files

Creating Filesystems

For e.g. the /boot partition it is necessary to create your own filesystem image. The example below gives you an idea how this is done.

Create an empty image, mount it, and put the files inside you need.

dd if=/dev/zero of=bootfs.fat bs=1M count=0 seek=32
mkfs -t vfat bootfs.fat
sudo mount -o loop bootfs.fat /mnt/temp/
sudo cp Image imx8mn-tx8m-nd00-mipi-mb.dtb /mnt/temp/
sudo umount /mnt/temp

Script Examples [1]

Hint

Some commands differ depending on the module you are using.

Module	Loading bootloader command-set	Comments
tx8m-1610	SDP: boot -f <mfg-uboot> SDPV: write -f <mfg-boot> -offset 0x57c00 SDPV: jump
