iMX8M Industrial Flashing Procedure

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

Installing Universal Upload Utility (UUU)

Linux

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.

Windows

• 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

Preparing the binaries

• Download the default bootloader file: imx-boot
• Download the default WIC filesystem image: voipac-image-imx8mq-voipac.wic

Flashing procedure

• 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:

eMMC Flash Memory (default)

Linux

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

Windows

uuu.exe -b emmc_all imx-boot voipac-image-imx8mq-voipac.wic

SD Card

Linux

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

Windows

C:\uuu>uuu.exe -b sd_all imx-boot voipac-image-imx8mq-voipac.wic

Running the newly flashed binaries

After completing the above steps, eMMC Flash memory or SD Card is flashed and the following steps are to be performed to boot the new image:

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