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 file: voipac-image-imx8mq-voipac.wic

Flashing procedure

For flashing eMMC or SD card we need to perform several steps:

1. change switch position S1 BOOT to: 1-off, 2-on (serial downloader mode)
2. plug USB-C cable to PC and to board USB C connector
3. prepare imx-boot and *.wic files
4. run following commands for flashing media

eMMC

Linux

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

Windows

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

SD

Linux

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

Windows

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:

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
