How to build STM32MPU distribution for Android
This article explains how to build the STM32MPU distribution for Android™. It is intended for Distribution Package users.
The environment must be installed using the Distribution Package adapted to your microprocessor device (see the list of Android Distribution Package).
In addition follow the PC prerequisites dedicated to Android to make sure all the packages required to use the environment are present.

Use the command below to list some interested aliases created by
If this is the first time you set up an environment to build Android, continue to read this article. Otherwise directly go to Choosing a build target.
2.1 Memory settings
The memory size and type can be changed. More information refer to How to customize the STM32MPU distribution for Android.
Locate the two lines below:
Current options are :
- PART_MEMORY_TYPE sd and PART_MEMORY_SIZE 8GiB
- PART_MEMORY_TYPE sd and PART_MEMORY_SIZE 4GiB
- PART_MEMORY_TYPE emmc and PART_MEMORY_SIZE 4GiB
When the file has been modified, relaunch the previous command:
Execute this <STM32Series> setup only once, for example for STM32MP1 Series:
It applies specific patches related to your <STM32Series> to customize Android and load the necessary libraries and modules.
2.3 Choosing a build target
To choose your target device, execute the command below:
build_type values are the following:
user: to generate an end-user production image;
userdebug: similar to an
userbuild but with root access and debug capabilities;
eng: development configuration with additional debugging tools.
2.4 Generating the image
You are now ready to compile. To do this, just launch the command:
Depending on your computer settings, several hours might be required to execute this command on the first build.
The result can be found in the
out folder. The generated partition images are located in
To flash images, refer to Flashing the built image.
