How to use UUU to flash the iMX boards

4 minute read

UUU is the next version of MFGTools, a tool used to load the software on the RAM or flash it to a list of boot media supported by several i.MX boards. UUU is helpful for development or production environment.

Introduction

UUU stands for Universal Update Utility - also known as mfgtools 3.0.

It runs on Windows or Linux with the same look and feel, the source code is available on GitHub along with the documentation, the issue tracking system and the release artifacts.

Installation

The installation only requires copying the right set of files to one directory. The next table shows the minimum files needed to get UUU running on Linux or Windows.

Linux Windows
uuu uuu.exe
  libusb-1.0.dll

How to use UUU for i.MX 8QXP MEK

The i.MX 8QXP MEK is shown in the following picture:

Connect the board

The first step is to connect all the needed cables to the board and power on the board.

  • Connect the 12V/8.3A universal power supply between the outlet and connector J9
  • Connect a USB type B cable between the computer and connector J11
  • Connect a USB type C cable between the computer and connector J10

The power indication led is D2. To verify if the USB connections are right use the Linux command lsusb or USBView on Windows.

The USB devices created are as in the following table:

USB Type Connector Use USB device recognized by OS
micro J11 Serial Console Bus 001 Device 006: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC
Type C J10 Serial Download Bus 003 Device 003: ID 1fc9:012f NXP Semiconductors

If using on Windows, additional drivers may be needed. This link may help.

Serial download mode

The serial download mode is used to enable UUU to communicate with the i.MX SoC. The SoC enters serial download mode every time a boot media is not found. For example, if the board is configured to boot from SDCard, but there is no SDCard connected or the boot media does not have a valid bootloader copied into it.

In this example, the SW2 dip switch is set to 1100 (follow the instructions written on the board).

Download the image

In this example the image used is from L4.14.62_1.0.0_Beta release. For i.MX 8QXP MEK download the pre-built image from here (you must read and decide if you accept the license).

UUU

UUU uses scripts with the same API used in MFGTools. The L4.14.62_1.0.0_beta release pre-built image already includes some script examples, a README file for UUU and the default script uuu.auto which flashes the default pre-built fsl-image-validation-imx-imx8qxpmek.sdcard to eMMC.

The files related to UUU are listed with the following command:

$ unzip -l ~/Download/L4.14.62_1.0.0_beta_images_MX8QXPMEK.zip | grep uuu
      160  2018-10-18 05:40   README.uuu

      546  2018-10-30 03:25   samples/example_weimnor.uuu
      454  2018-10-30 03:25   samples/uuu.auto
     2795  2018-10-30 03:25   samples/example_kernel_nand.uuu
      434  2018-10-30 03:25   samples/example_sata.uuu
      591  2018-10-30 03:25   samples/uuu_sd_m4.auto
      570  2018-10-18 05:41   uuu.auto

The default use of UUU is to flash the eMMC using the pre-built image is show bellow:

$ cp ~/Download/uuu .
$ chmod a+x uuu
$ sudo ./uuu ~/Download/L4.14.62_1.0.0_beta_images_MX8QXPMEK.zip
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.1.108-0-g5a7bfd2

Success 1    Failure 0

This command follows the instructions from uuu.auto automatically to flash the board.

The progress can be followed in the board console:
