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…

http://www.ethernut.de/en/hardware/turtelizer/ Introducing Turtelizer 2 Overview Turtelizer 2 had been developed to provide JTAG Flash programming and debugging of ARM based boards via USB. Typical target boards are Ethernut 3 , the Elektor Internet…

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…

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…

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…

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…

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…

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…

MDK开发环境从V4升级到V5后,支持包不再是集成到开发环境当中,而是封装在PACK中,需要自行安装,比较麻烦. 搭建MDK开发环境以及破解的方法,在前面的文章中有详细说明,这里不再赘述,有兴趣的可以参考:http://www.cnblogs.com/huanzxj/p/6200928.html 搭建好开发环境,在编译完代码需要下载的时候,需要选择下载算法:add flash programming algorithm,这时候可能会遇到本文锁讲述的问题,找不到与你使用的MCU 对应资源的软件算法…

注明来自 http://www.ssdfans.com/?p=5589 以MLC为例: 对FGF(Floating Gate Flash)技术的,MLC programming一般分两步走:先program Lower page,然后program Upper Page. 对某个Cell来说,当写入1时,无需Programming,阈值电压保持不变,还是处于E状态:当写入0时,必须进行Programming,使它的阈值电压落到D范围 ,即E->D. Programming某个page时,往其所在…
