Essential Kernel Course for BSP Engineers: 2.6 Complete Analysis of the Dynamic Loading Process of Kernel Modules from Compilation and Linking to insmod

This article will provide a complete analysis of the dynamic loading process of kernel modules. To emphasize, we are organizing the dynamic loading process in this section, which involves compiling into a <span>ko</span> file and using the <span>insmod</span> method to load it, which differs from the <span>built-in</span> process where the kernel automatically loads modules. First, … Read more

The Architect's Secret Weapon: Decoding the Java SPI Plugin Mechanism

Silence is golden, but it will eventually shine. Hello everyone, I am Silent. As a Java developer, have you ever encountered this dilemma: as the project grows larger and features keep piling up, you find that the core code’s coupling degree is increasing, and replacing a certain component requires significant changes, even a complete refactor? … Read more

A Complete Guide to Function Pointers in C: From Basics to Advanced Applications

Function pointers are a powerful feature in the C programming language, allowing programs to pass, store, and dynamically call functions as data, providing great flexibility in code design. This article will systematically explain function pointers from their definition syntax, basic usage to advanced applications (callback mechanisms, state machines, plugin systems, object-oriented simulation), combining core insights … Read more

SpringBoot + SPI Mechanism: Easily Implement Pluggable Components

Java SPI (Service Provider Interface) is a service provider interface that provides a service discovery and loading mechanism in Java, allowing developers to define multiple implementations for an interface and dynamically discover and load these implementations at runtime. The core of the Java SPI mechanism is that it provides a way for service providers to … Read more

Java SPI Mechanism: The 'Service Dispatcher' Hidden in the META-INF Directory

Core Idea of SPI Mechanism SPI (Service Provider Interface) is a service discovery mechanism that allows frameworks or libraries to dynamically load implementation classes of interfaces at runtime, achieving module decoupling and pluggable extensions. The core process is as follows: Define the interface (Service Provider Interface). Write multiple implementation classes for the interface. Register the … Read more

A Method for Dynamically Loading Functions in MCU

by
A Method for Dynamically Loading Functions in MCU

We have all heard of static libraries and dynamic libraries. Static libraries are quite familiar to everyone, especially in microcontroller development. Dynamic libraries, however, are rarely seen in the microcontroller field. Today, I would like to share a method for dynamically loading functions, which is somewhat similar to dynamic libraries. Project Address: printf("hello world!"); Introduction … Read more

Dynamic APP Loading Techniques for Microcontrollers

by
Dynamic APP Loading Techniques for Microcontrollers

Dynamic APP loading techniques for microcontrollers are similar to applications on mobile phones and computers, allowing programs to be loaded from various sources such as SD cards, NAND, NOR, eMMC, etc., into execution spaces like SRAM, SDRAM, QSPI Flash, and internal Flash. Moreover, if MPU support is available, it can isolate APPs; if an APP … Read more
