This page describes how to flash binaries into iMX93 Industrial Module's eMMC Flash memory or into SD card that is located on the iMX Development Baseboard.

Note: All of the steps listed below are NOT REQUIRED for standard configuration modules and development kits.

Installing Universal Upload Utility (UUU)

Linux

git clone https://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

Preparing the binaries

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
    Note: Make sure that UART1 and UART2 jumpers are in CP2105 positions (USB/UART bridge).

  • Plug USB-C cable to baseboard USB-C connector and PC
    Note: Powering of the development kit is not required during the flashing procedure.
    Note: After connecting 2 development board cables, 2 serial ports named Silicon Labs CP210x USB to UART Bridge should appear in the controlling PC.

  • 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-imx93-pro.rootfs.wic

Windows

uuu.exe -b emmc_all voipac-image-imx93-pro.rootfs.wic

SD Card

Linux

sudo ./uuu -b sd_all voipac-image-imx93-pro.rootfs.wic

Windows

uuu.exe -b sd_all voipac-image-imx93-pro.rootfs.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:

  • Unplug USB-C cable from PC
  • Set Boot mode by sliding DIP switch S1 BOOT positions to: 1-ON, 2-OFF

  • Make sure that S2 BOOT and S3 BOOT DIP switches are in correct positions in order to boot from the selected storage media (eMMC Flash memory or SD Card):

eMMC Flash Memory boot (default)
