Design of software and hardware platform based on ARM9 core

Embedded application system design includes two parts: hardware platform and software platform. The former is a hardware system with embedded microcontroller/microprocessor as the core; the latter is a software system built around embedded operating system. The two are inseparable in design, and it is necessary to bal

Detailed analysis of the ARM Linux boot process

The analysis of the ARM Linux boot process is what I want to introduce. The portability of embedded Linux allows us to see it in various electronic products. The Linux boot process is also different for processors with different architectures. This article takes the S3C2410 ARM processor as an example to analyze in de

ARM uses the terms flush and clean to refer to the basic operations on the cache.

Clearing the cache means clearing all the data stored in the cache. For the processor, the clear operation is to clear the valid bit of the corresponding cache line. When there is a change in the memory configuration, the whole or part of the cache may need to be cleared. Sometimes the term invalidate is used instead

Learn ARM development (6)

Last time, I talked about learning ARM assembly. OK, let's start now. My boot program is modified from UBOOT1.1.2. You can download the source code of UBOOT. Maybe you will ask where to download it? I don't need to answer this question. Just use GOOGLE and search for u-boot. You can find it. Since this boo
