    rk356x-android13-*.tar.gz

  • Copy the source code compressed package to the compilation host directory If the compilation host is a virtual machine, do not place it in the shared directory for compilation.

  • Verify the integrity of the file using MD5

$ md5sum -c *.md5

  • Extract the source code compressed package

$ tar -zxvf rk356x-android13-*.tar.gz

Compile the Complete Image

Select the corresponding compilation command according to the CPU model. If the compilation fails, you can try to solve it yourself or contact the technical support team.

Configure the SDK compilation items

After the configuration is selected, the software will be configured for the selected device. If you need to switch devices, you need to reconfigure; otherwise, there is no need to configure multiple times.

Compile the complete image

Image generation directory: rockdev/Image-/update-.img

You can configure the compilation thread option and specify 32 threads.

Note: If the compilation fails when building Android without specific error messages, it is likely that the virtual machine configuration is too low. You can modify the default configuration in the build.sh file and try again.

Insufficient Configuration

Common log errors due to insufficient memory configuration

  • Killed appears

  • Solution: Increase the actual memory. Generally, 32G of memory is recommended for Android. If you cannot increase the actual memory, you can try to increase the size of the swap partition and use single-threaded compilation. Configure the thread option and specify single-threaded compilation.
