Being able to display values for counters, sensors and other debugging information is an important part of software development for microcontrollers.  Writing software for PCs is much easier in this regard as there is already a monitor to which you c…

PSoC 5 supports programming through the serial wire debug (SWD) interface. There are two signals in SWD interface: data signal (SWDIO) and a clock for data signal (SWDCK). The host programmer always drives the clock line, whereas either the programme…

SW-DP (Serial Wire Debug Port) Analyzer plugin for the Saleae Logic The SW-DP protocol is described by the following publicly available documents: DDI 0316 CoreSight™ DAP-Lite Technical Reference Manual Programming Internal Flash Over the Serial Wire…

1 Debug Interface Overview 1.1 Serial Wire Debug Serial Wire Debug (SWD) is a two-wire protocol for accessing the ARM debug interface. It is part of the ARM Debug Interface Specification v5 and is an alternative to JTAG. The physical layer of SWD con…

Serial Wire Debugging the STM32 via the Bus Pirate 2 October 2010 Step 1 - The Bus Pirate Step 2 - Debug Port Communications Step 3 - Access Port Communications Step 4 - Processor State Step 5 - Programming the Flash Step 6 - Optimizing Conclusion So…

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…

Serial Wire Debug (SWD) provides a debug port for severely pin limited packages, often the case for small package microcontrollers but also complex ASICs where limiting pin-count is critical and can be the controlling factor in device costs. SWD repl…

一.概述 1.说明 笔者已经写了一篇Linux下STM32开发环境的搭建 ,这两篇文章的最区别在于开发环境所处的系统平台不一样,而其实这个区别对于开发环境的搭建其实影响不大,制作局部上的操作上发生了改变.鉴于此,本文没有必要对windows下搭建STM32开发环境的详细过程进行阐述,读者可以结合Linux下STM32开发环境的搭建和本文进行windows下STM32开发环境的搭建. 2.开发环境描述 硬件开发板:野火STM32开发板 Cortex-M3型号:STM32F103VET6 下载器与调…

One of the basic needs of the embedded software development through the terminal to output debugging information, generally two ways to achieve: one is the COM port on the UART and PC using a serial cable connecting plate through the PC HyperTerminal…

ARM Cortex-M processor-based devices use the ARM CoreSight technology which introduces powerful new debug and trace capabilities. Debug features: Run Control of the processor allowing you to start and stop programs Single Step one source or assembler…
