This page describes how to flash binaries into iMX8M Industial Module's eMMC Flash memory or SD card.

git clone ssh://git@github.com/NXPmicro/mfgtools.git
cd mfgtools
mkdir .build && cd .build && cmake .. && make -j`nproc`

The binary called uuu, which is used for flashing, is located in .build/uuu directory.

Go to: https://github.com/NXPmicro/mfgtools/releases
Select the latest stable release.
Example: Releases/uuu_1.4.243: https://github.com/NXPmicro/mfgtools/releases/tag/uuu_1.4.243
Download: uuu.exe
Save the file into: C:\uuu

Set serial downloader mode by sliding DIP switch S1 BOOT positions to: 1-OFF, 2-ON

Plug USB Micro-B cable to baseboard CONSOLE connector and PC
Plug USB-C cable to baseboard USB-C connector and PC
Note: Powering of the development kit is not required during the flashing procedure.
Download and copy imx-boot and *.wic files into uuu\ directory
Choose one of the following commands to start the flashing process:

sudo ./uuu -b emmc_all imx-boot voipac-image-imx8mq-voipac.wic

C:\uuu>uuu.exe -b emmc_all <path to imx-boot file> <path to wic file>

sudo ./uuu -b sd_all <path to imx-boot file> <path to wic file>

C:\uuu>uuu.exe -b sd_all <path to imx-boot file> <path to wic file>

After those steps eMMC or SD card is flashed and perform following steps to boot new image:

unplug USB-C cable from PC
change switch position S1 BOOT to: 1-on, 2-off (boot mode)
be sure that S2 BOOT and S3 BOOT switches are in proper position to boot from desired peripherals (eMMC or SD)
connect debug UART and power on board and messages should appear on serial console
