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
TIOBE has updated the programming language rankings for July 2016, and the biggest highlight this month is that the low-level assembly language has once again entered the top 10. Many people are surprised by the reasons that have led this low-level programming language to re-enter the top 10. They do not understand why a language … Read more

01 What is a BootLoader? It is a boot program, which is the first program to execute after hardware reset. Its main job is to initialize the environment for the operating system to run, such as memory, timers, buffers, etc. Once this is done, it loads the operating system’s code into memory, and then the … Read more

Low-Level Systems Application Development If you want to do application development, then you should learn C, data structures, JAVA, and so on. There is nothing particularly different about embedded application development compared to PC application development. You might say that optimization is necessary in embedded systems, and yes, optimization is required, but an unoptimized program … Read more
Recently, I have been learning about system porting. During the process of learning and debugging, I encountered and solved many problems, but I always felt a vague sense of confusion about our development results. Upon reflection, the main reason is that we do not have a profound understanding of our development environment. Sometimes, a few … Read more
For embedded Linux systems, the process from powering on to the operating system startup requires a boot process, which is reflected in the boot program, known as the Bootloader. Concept and Role of Bootloader The Bootloader is the boot program for embedded systems, and it is the first program that runs after the system powers … Read more
When it comes to flashing firmware, everyone is familiar with it. The essence of flashing is to update all or part of the programs in the chip and external memory of embedded products. Based on the various methods of programming chips involved from PCB production to R&D debugging, assembly, and finally to the user, today … Read more
