SWD其实和JTAG类似,是一种调试串口. JTAG大致了解了一下.JTAG(Joint Test Action Group)主要4 lines:TMS(模式选择),TCK(时钟),TDI(数据输入),TDO(数据输出).都是串行总线.JTAG model中通过状态机的方式,对cmd进行解析后控制TMS和TDI的输出. SWD(Serial Wire Debug)主要2 lines: SWDIO(双向串行数据线),SWDCLK(串行时钟线,Master drive).协议:ARM CPU sta
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
Serial Wire Debug interface The Serial Wire Debug protocol operates with a synchronous serial interface. This uses a single bidirectional data signal, and a clock signal. This section gives an overview of the physical Serial Wire Debug interface. Lin
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
SWD and JTAG selection mechanism SWJ-DP enables either an SWD or JTAG protocol to be used on the debug port. To do this, it implements a watcher circuit that detects a specific 16-bit selection sequence on the SWDIOTMS pin: A 16-bit sequence is used
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
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
