The command for system services is saved in the /usr/etc/rc.local file of the development board’s root filesystem. Some development boards need to hold down ctrl+c to enter the Linux SHELL prompt after booting to automatically run graphical interface programs. In fact, you can achieve the goal of automatically running user applications at boot by commenting … Read more
Abstract: The cross-development environment is the foundation of embedded Linux development. The subsequent development process is almost entirely based on this environment. ARM, as a high-performance, low-cost embedded RISC microprocessor, has become the most widely used embedded processor. This article includes the hardware structure of the 32-bit ARM920T core “GEC2410” development board and the concept … Read more
The previous article “Analysis of WiFi Configuration Scripts in Embedded Linux” introduced how to configure WiFi on embedded Linux development boards using shell scripts to call tools like wpa_supplicant. This article will introduce how to achieve the same functionality through C++ programming. 1. Preparation My development board previously had a script set to automatically start … Read more
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
Before discussing the issues in this article, let’s first talk about a topic: “Currently, CP Autosar supports Some/IP and DDS (Data Distribution Service). DDS seems just another protocol; is it really necessary to implement DDS in vehicles?” Regarding this question, I would like to share my personal understanding. In CP Autosar, Some/IP appeared earlier, and … Read more
