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

The noinit section is familiar to most of us developers working with microcontrollers. If this section is used, it will be automatically allocated by the compiler to a region in the chip’s SRAM (note that it is in the RAM area, not Flash). Variables defined in this section will not be re-initialized during any chip … Read more
Assembly Language, for those who have never delved deeply into it, can be incredibly arcane. Since our computers are developed based on assembly language, understanding this content will greatly help us clarify how the CPU works. The X86 computer is fully backward compatible with the IBM PC – from the top level of the system … Read more
