1. Compiling U-Boot First, let’s review how to compile U-Boot. (1) Set temporary environment variables export ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- (2) Specify board configuration and generate .config file make xxx_defconfig (3) Compile make -j8 (4) Clean build make distclean Next, we will analyze the top-level Makefile in the U-Boot root directory to explore what happens behind these … Read more
The Linux kernel source code contains numerous files, and understanding the relationships between Makefile, Kconfig, and .config is crucial for navigating the kernel compilation system. Issues arise when trying to compile and modify the kernel, integrate your own drivers, or configure the kernel. All of these problems relate to Makefile, Kconfig, and .config. Below, I … Read more
Automatically check if target files or source files exist. If the source files are not found, exit the make process. If the target files are found, skip this make step. Automatically check for changes in target files or source files. If the source files are modified, regenerate the corresponding target files. Easy to run multiple … Read more

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
Follow for more updates, let’s go From Zero To Hero! Introduction In Go language development, we want to standardize code style so that each member can format code with one click and check for syntax errors; we want to run unit tests, generate test reports, and compile, package, and release projects with one click, which … Read more
