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 imx-mfg-uuu-tool_20200629.zip
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: 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
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.
