7.2.1 Development Environment Setup and Compilation Instructions

This chapter introduces the requirements and setup of the cross-compilation development environment, as well as instructions for downloading the source code and compiling the system image.

Cross-compilation Development Environment​

Cross-compilation is a method of developing and building software on a host machine, with the resulting software deployed to the development board for execution.

  • Host Characteristics: The host machine typically has higher performance and larger memory capacity, which significantly accelerates the build process.
  • Tool Support: The host machine can support more development tools, enhancing development efficiency.

Setting up a cross-compilation environment is an essential step in the development process. The following diagram illustrates the overall framework of the cross-compilation environment:
