mastering-embeded-linux-programming

This is a complete guide to bring a embedded board using qemu steps by steps. Start from building a cross-compiler, u-boot, linux and root filesystem.

For more details, the guide steps can be looked at the book: mastering embedded linux programming.

Build with docker

If your PC is running unbuntu with different version of 20.04 as this guide. To avoid errors(mismatch linux version, can not install requirement packages, etc) when building, there is a simple docker in this guide that can be used.

  • Build docker: 
    cd DockerBuild
docker build -t build_machine_crosstoolng .
  • Run docker in attach mode: 
    docker run -t -d --name crosstoolNg build_machine_crosstoolng
  • Enter the container in interact mode 
    docker exec -it crosstoolNg bash

Output:
dummier@63e01c29ddaa:~$
dummier@63e01c29ddaa:~$

Then you will be in the terminal, from there you can start to build with the command line followed this guide.
