Here you can choose from 5 desktop configuration types. Enter the corresponding number:

Function Description

This will write the configuration from tspi_3m_rk3576_buildroot_defconfig to output/.config for compilation.

You can use ./build.sh help to view other command parameters.

2⃣. Start compilation with one click:
