This repository is a "simple" guide on how to build U-Boot, Linux kernel, and Rootfs from scratch for the linux embedded system.

You'll need the following programs installed on your machine

• GNU Make for running the Makefile
• python and python-dev
• swig: Generate scripting interfaces to C/C++ code
• ccache: caches the output of C/C++ compilation so that the next time
• dh-autoreconf: debhelper add-on to call autoreconf and clean up after the build
• net-tools: NET-3 networking toolkit, required for building OpenVPN
• cmake: for building some opensoucre apps

In ubuntu, run the following command to install all of them:

sudo apt-get install -y build-essential python python-dev swig ccache net-tools dh-autoreconf cmake

git clone https://github.com/hhdang6637/embedded_linux_skeleton.git

To compile and run the example project, run the following commands:

export MODEL=arm_vexpress_a9cd embedded_linux_skeletonmake

After that, we have theuboot,kernel, androotfs image files atbuild/bin/

• Install QEMU:

sudo apt install qemu-system-arm

• Run QEMU with Kernel and Rootfs:

First, run the following command:

./qemu_scripts/qemu_kernel_roofs_start.sh
