Introducing swddude I love the ARM Cortex-M series of microcontrollers.   The sheer computational power they pack into a teensy, low-power package is almost embarrassing. But, many Cortex-M parts are small — 4x4 millimeters small — and don’t have the…
Implementation of Serial Wire JTAG flash programming in ARM Cortex M3 Processors The goal of the project was to use the Serial Wire JTAG protocol implemented in the ARM cortex processors for programming the flash memory of it. JTAG was actually imple…

ARM7 ARM9 ARM Cortex M3 M4 区别 arm7 arm9 可以类比386和奔腾, 不同代,arm9相比arm7指令集和性能都有所增强,arm7和arm9都有带mmu和无mmu的版本,不过大多的arm7都不带,而大多的arm9的都带.所以一般是arm7跑实时操作系统像ucos做简单的控制应用,而arm9跑linux,cortex是更新一代,分高端的A系列和和低端的M系列,来接arm9和arm7的班 一般情况下ARM7 Cortex-M3 Cortex-M4可以认为是一类,M3…

JTAG was the traditional mechanism for debug connections for ARM7/9 parts, but with the Cortex-M family, ARM introduced the Serial Wire Debug (SWD) Interface. SWD is designed to reduce the pin count required for debug from the 5 used by JTAG (includi…
Cortex-m3启动代码分析笔记 启动代码文件名是STM32F10X.S,它的作用先总结下,然后再分析. 启动代码作用一般是: 1)堆和栈的初始化: 2)中断向量表定义: 3)地址重映射及中断向量表的转移: 4)设置系统时钟频率: 5)中断寄存器的初始化: 6)进入C应用程序. (1)按启动代码的次序,先看堆和栈的初始化: Stack_Size EQU 0x00000200 ;定义Stack_Size为0x00000200 AREA STACK, NOINIT, READWRITE, ALIG…
