Hi Richard,

Thank you for reaching out to us,

The instruction should be:

1. clone the mfgtools project [GitHub - NXPmicro/mfgtools: Freescale/NXP I.MX Chip image deploy tools.](https://github.com/NXPmicro/mfgtools) to use the uuu tools
2. follow the build instruction (you should make sure that you success to build the project, the output should be mfgtools/uuu/uuu exec file)  
Note: If you use linux machine & not success to build the project make sure that you have the correct cmake version (it’s should cmake version 3.19.4+, I test it with 3.19.4 version - works fine)
3. Connect the USB to USB cable, from your pc to the USB OTG (the upper one in the HB-Pluse/Ripple EVK)
4. Configure the boot switch (S3) to boot in serial mode -follow this page [HummingBoard Pulse and Ripple Boot Select | SolidRun](https://developer.solid-run.com/knowledge-base/hummingboard-pulse-ripple-boot-select/)
5. Connect the power
6. Make sure that you detect the USB = NXP Semiconductors in the USB List with the exactly vendor id:  
Device 014: ID 1fc9:0146 NXP Semiconductors
7. Run the script uuu exec with the flash.bin [1] (of the imx8mp), to load the U-Boot  
you should run the command below with sudo:  
cd /mfgtools/uuu/  
sudo ./uuu \<flash.bin-dir\>/flash.bib  
[1]: You can use this binaries [https://solid-run-ignition.sos-de-fra-1.exo.io/imx8mp/Buildroot/flash-uboot-1g-and-3g.bin](https://solid-run-ignition.sos-de-fra-1.exo.io/imx8mp/Buildroot/flash-uboot-1g-and-3g.bin)  
Note: You can build your own image using the runme.sh script here – [GitHub - SolidRun/imx8mp\_build: IMX8M Plus buildroot build script](https://github.com/SolidRun/imx8mp_build)  
the flash.bin should be under $ROOTDIR/build/imx-mkimage/iMX8M/flash.bin

Let me know if you have any issues with this, let me know at what stage it got stuck  
We will do our best to help  
Best Regards,  
Yazan.
