3.3 Flashing board images

The board image files can be flashed into the target board using Universal Update Utility (UUU).

For the UUU binary file, download it from github: uuu release page on github. You can download the latest version (1.2.31

for now).

• For Linux OS, download the file named "uuu".

• For Windows OS, download the file named "uuu.exe".

You can put these files in a path containing the system environment variable "PATH", and then directly call uuu in

command line or shell terminal.

There are two ways as follows to use UUU to flash images:

• Directly invoke UUU with the lst scripts in the command line to flash images.

• Use the uuu_imx_android_flash shell script and Windows batch file to invoke UUU and fastboot tool to flash images.

uuu_imx_android_flash is a new tool, which is more flexible. If the users are not familiar with this tool, the way to use UUU

with the lst scripts is still maintained, and it will be removed in the future.

The two ways are described as follows. Users can choose either of it to flash images.

3.3.1 Directly invoking UUU with the lst scripts in command line to

flash images

For detailed information on the UUU lst scripts used in this way, see Section 3.2 "Board images".

NOTE

UUU uses the integrated fastboot tool to flash images. Make sure you have fastboot

driver software installed on your computer.

Perform the following steps to flash the board images:

1. Download the UUU binary file from github as described above.

2. Change the first two bits of the board's sw1101 to 10 (1-2 bit) to enter serial download mode.

3. Power on the board. Connect the PC with the board using the USB cable on the board's OTG port.

4. Decompress release_package/android_p9.0.0_1.0.0-ga_image_8mmevk.tar.gz, which contains the image files and

UUU scripts. Choose the correct UUU script file as shown in the following table.

Target device and boot storage UUU script file

i.MX 8M Mini EVK eMMC uuu-android-mx8mm-evk-emmc.lst

i.MX 8M Mini EVK SD uuu-android-mx8mm-evk-sd.lst

To test MIPI-DSI to HDMI output and audio playback based on Cortex-M4 FreeRTOS, choose one of the UUU scripts

shown in the following table.

Target device and boot storage UUU script file

i.MX 8M Mini EVK eMMC uuu-android-mx8mm-evk-emmc-m4.lst

i.MX 8M Mini EVK SD uuu-android-mx8mm-evk-sd-m4.lst

NOTE

• If your SD card is 16 GB or the on-board eMMC is used as the boot device,

to test the MIPI-DSI to HDMI output, you do not need to change the

"partition-table.img" part of the UUU script.

• If your SD card is 32 GB, rename partition-table.img to partition-

table-28GB.img in the corresponding UUU script.

• If your SD card is 8 GB, rename partition-table.img to partition-

table-7GB.img in the corresponding UUU script.

• To test MIPI-DSI to HDMI output, you do not need to rename boot-

imx8mm.img and vbmeta-imx8mm.img in the UUU scipt.

• To test the MIPI panel output, rename boot-imx8mm.img and vbmeta-

imx8mm.img to boot-imx8mm-mipi-panel.img and vbmeta-imx8mm-mipi-

panel.img in the corresponding UUU script.

5. Use UUU and the proper script file to flash image files.

Execute the following command to invoke the UUU binary file and UUU scripts to flash the image files.

• On a Linux system, open the shell terminal. Execute the command below. ${uuu_script_path} is the file path

(including the name of the UUU script) of the UUU script that is used. It can be a relative path or an absolute

path.

> sudo uuu ${uuu_script_path}

• On a Windows system, open the command line interface. Execute the command below. ${uuu_script_path}

is the absolute file path (including the name of the UUU script) of the UUU script.

> uuu.exe ${uuu_script_path}

6. Wait for the script file execution to complete. If there are no errors, you will get information on the command window

as follows:

C:\Users\user_01\tools\uuu>uuu.exe C:\Users\user_01\images\android_p9.0.0_1.0.0-

ga_image_8mmevk\uuu-android-mx8mm-evk-emmc.lst

uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.2.24-0-g0d63ca3

Powershell: Enjoy auto [tab] command complete by run below command or put into

Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1

$parameterName,$wordToComplete,$commandAst,$fakeBoundParameter); C:\Users\user_01\tools

\uuu>uuu.exe -autocomplete $parameterName }

Success 1 Failure 0

2:2 22/22 [Done ] FB: done

As you can see, it is on the Windows system, and the absolute file path of the UUU script is used. For the output

information on the command complete feature, it is recommendations given by UUU itself. This feature is not used

here.

7. Power off the board.

8. Change the boot device as eMMC or SD card.

• To boot from eMMC, change sw1101 to 01110010 and change sw1102 to 00101010.

• To boot from SD card, change sw1101 to 01000110 and change sw1102 to 00110100.

3.3.2 Using the uuu_imx_android_flash tool to invoke UUU and

fastboot tool to flash images

The uuu_imx_android_flash shell script and windows batch file are provided to flash Android images with much more

flexibility.
