The last time we talked about how to build a LinuxDevelopment environment. This time, we will build our own cross-compiling environment for ARM-Linux based on different target platforms.There are many ways to build a cross-compiler environment. different architectures, different operations, and even different kernel ve

We also need to install a cross-compilation tool before we can formally begin to write the bare-metal program. What is a cross-compilation tool? It is actually compiling the program on the x86 Ubuntu host and can run the build tool in the ARM environment. GCC is the local compilation tool, which has been installed at the beginning of this article. Now we need to

Before embedded development, you must first establish a cross-compilation environment, which is a development environment consisting of a set of compilers, connectors, and libc libraries. This article describes the establishment process and operation steps of the embedded cross-compilation environment, hoping to help y

(Platform Plugins for Embedded Linux Devices) Eglfs: EGL is the interface between OpenGL and the local window system. QT can be used for context and surface management with EGL, but the API does not include platform-specific: Creating a local window (which is not necessarily a real window on the screen) still has to be done through a platform-specific method.
