As we all know, embedded devices generally have limited storage and resources, which is why a command system for embedded devices called BusyBox has emerged. The characteristic of BusyBox is its powerful functionality while occupying a small storage capacity. Below, I will introduce how to download and compile BusyBox for your embedded device. Introduction to … Read more
Introduction In a previous article, we introduced how to use busybox to build a filesystem: https://www.guyuehome.com/detail?id=1928835293522231297 However, the filesystem built with busybox requires a lot of cross-compilation and manual addition of components, and some software needs to be ported by yourself, making the porting process quite cumbersome. There is another very practical method for building … Read more

Introduction This article provides a brief overview of some knowledge related to Embedded Linux, serving as a reference for those who, like me, wish to advance from microcontroller programming to Embedded Linux. With the increasing number of tutorials on Embedded Linux, I believe many friends studying microcontrollers have started to explore this area. What to … Read more
Introduction The project development requirement is to automatically create a user with a password after booting. The provided SDK only has the adduser command. This command requires terminal interaction when adding a user. It requires manually entering the password twice, so it cannot be created simply through a script. To achieve automatic password filling, we … Read more
