General Makefile Application Guide for Advanced Embedded Programming

Introduction For development on Windows, many IDEs integrate compilers, such as Visual Studio, providing a “one-click compile” feature, allowing the user to compile, link, and generate target files with just one operation after coding. Linux development differs from Windows; the gcc/g++ compiler is generally used in Linux. If developing Linux programs for ARM, the arm-linux-gcc/arm-linux-g++ … Read more

Understanding Makefile, Kconfig, and .config in Linux Kernel

When compiling the Linux kernel, we often execute some commands in the top-level directory of the Linux kernel. Taking RK3288 as an example, commands include: make firefly-rk3288-linux_defconfig, make menuconfig, make firefly-rk3288.img, make zImage, etc. Without delving into the specific meanings yet, I would like to raise a few questions. (1) The Linux kernel is so … Read more
