Connect debug console, power, and data cables to the baseboard

Yellow box: debug console cable
Red box: power cable (Note: some boards are powered using USB Type-C cable)
Magenta box: Boot mode jumper location

this is testcode


Unzip the package

After you download it, you will need to unzip the package:

$ unzip

If you are using a Linux-based host, by default files unpacked using unzip are not executable. You may need to set the execute flag on the ‘uuu’ binary in order to execute it (run it).

$ cd imx-mfg-uuu-tool
$ chmod +x uuu/linux64/uuu

Download a default TechNexion Software Loader image for your board

The following table lists the URLs based on the SOM and baseboard you are using. Please make sure to correctly identify the board you have.

Download locations (PICO-IMX8M-MINI)

note Note: For historical reasons, the filename starts with 'rescue' (as the original system was called the 'rescue loader').

Unpack the rescue loader binary image

After download, you’ll need to unpack the rescue loader binary from the “xz” archive. This results in a file named “rescue” in the current directory, and the archive file (rescue.xz) is deleted.
$ unxz rescue.xz

Note that if you directly write the archive file (“rescue.xz”), the process may appear to complete successfully, but in fact this is quite incorrect and the board will not boot. ‘uuu’ is smart enough to look into .bz2 archives, but not .xz archives.

Write the rescue loader image to EMMC

This assumes that you are in imx-mfg-uuu-tool directory.

For Linux Platforms:

sudo ./uuu/linux64/uuu -b emmc_img imx8mm/pico-imx8mm-flash.bin

For additional information, please see the article: Using 'uuu' to flash e.MMC on PICO-IMX8M-MINI

Set the boot jumpers back to boot from eMMC and reboot

You should be presented with the TechNexion Software Loader UI.
