I want to write the images including Image, dtb, rootfs, bootloader etc files into the eMMC on the iMX8M Mini by uuu, therefore I strictly execute following documents:

1.- uuu.pdf 

2.- Linux User Guide.pdf 

I am executing the following steps:


1.- downloading the L4.14.98_2.0.0_ga_images_MX8MMEVK from nxp website

2.- downloading the rececently uuu.exe from github Release 1.3.102 · NXPmicro/mfgtools · GitHub 

3.- Connect the USB power supply to the J302 connector (the USB Type-C POWER connector)

4.- Connect the USB Type-C cable from the serial download connector (J301) to the host machine

5.- Connect the serial debug (connector J901) to the host machine using a USB micro-B cable

6.- Set the boot mode switches to the Download Mode (see sticker or silk on the board)

7.- Turn on the board on ON switch (SW101)

8.- Open CMD

9.- In the CMD, execute: uuu.exe

10.- Turn on the board on OFF switch (SW101) and set the boot mode switches to the eMMC/SDHC3

In the PUTTY terminal I see these messages continuously:
