To achieve more flexibility, two script files are provided to invoke UUU to automatically flash all Android images.
• uuu_imx_android_flash.sh for Linux OS
• uuu_imx_android_flash.bat for Windows OS
For this release, these two scripts are validated on UUU 1.2.91 version. Download corresponding version from github:
• For Linux OS, download the file named "uuu".
• For Windows OS, download the file named "uuu.exe".
Because the two script files will direclty invoke UUU, make sure that UUU is in a path contained by the system environment
variable of "PATH".
Perform the following steps to download the board images:
1. Download the UUU binary file from github as described before. Install UUU into a directory contained by the system
environment variable of "PATH".
2. Make the board enter serial download mode.
• For Rev. B boards, change the first two bits of board's sw1101 to 10 (from 1-2 bit) to enter serial download
mode.
• For Rev. C boards, change the first four bits of board's sw1101 to 1010 (from 1-4 bit) to enter serial download
mode.
3. Power on the board. Use the USB cable on the board OTG port to connect your PC with the board.
4. Decompress release_package/android_p9.0.0_2.0.0-ga_image_8mmevk.tar.gz, which contains the image files and
uuu_imx_android_flash tool.
5. Execute the uuu_imx_android_flash tool to flash images.
The uuu_imx_android_flash tool can be executed with options to get help information and specify the images to be
flashed. For i.MX 8M Mini board, related options are described as follows
