What is an SWD programmer?
SWD, also known as Serial Wire Debug is a 2-pin interface (SWDIO/SWCLK) of which it’s also an alternative JTAG interface that has the same JTAG protocol. SWD uses an ARM CPU standard bi-directional wire protocol, defined in the ARM Debug programmer.
What is the difference between JTAG and SWD?
SWD is an ARM specific protocol designed specifically for micro debugging. JTAG (Joint Test Action Group) was designed largely for chip and board testing. It is used for boundary scans, checking faults in chips/boards in production.
What is JTAG programmer?
Universal In-System Programming Tool. ScanExpress JTAG Programmer is a universal in-system programming (ISP) solution designed for convenience and versatility—a modular, multi-functional, and high-performance tool to program, read, and verify Flash memories, serial EEPROMs, CPLDS, FPGAs, and more.
How do you use particle debugger?
Click the bug icon in the VS Code / Workbench sidebar to open the debug sidebar. Click the debug configurations dropdown and select the Particle Debugger (Argon or Boron) option. Finally, click the green arrow next to the debug configuration dropdown to initiate the debug process.
What is SWD protocol?
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.
What are the SWD signals?
Serial Wire Debug (SWD) is commonly used on reduced pin-count target devices. SWD only requires two pins, instead of the four pins used by JTAG.
What is USB JTAG?
The JTAG-USB cable allows you to use your PC to connect to a JTAG scan chain or to access an SPI interface on a board equipped with the appropriate 6-pin header. In this way, you can program devices on Digilent programmable logic boards using the Digilent Adept Suite.
Why is JTAG needed?
JTAG is there for a reason…it’s there because Manufacturers need it for everything from validating proper assembly of the circuit board to loading firmware on the device… JTAG is incredibly useful to chip manufacturers during design, testing, and production phases.
How do you open the particle on a serial monitor?
In Particle Workbench (VS Code), open the command palette (Command-Shift-P on the Mac, Ctrl-Shift-P on Windows and Linux) and select Particle: Serial Monitor.
What is particle workbench?
Particle Workbench provides all the tools, libraries, and extensions you need for IoT development in a single, easy-to-install package. By utilizing Microsoft’s Visual Studio Code as an editor, you get a lightweight, yet powerful experience that can build, compile, and deploy code for your Particle-powered Products.
What is the role of the SWD connector?
JTAG/SWD Connector In SWD mode, two pins are used for debugging: one bi-directional pin (SWDIO) transfers the information and the second pin (SWDCLK) clocks the data. A third pin (SWO) delivers the trace data at minimum system cost.
How the SWD protocol works?
SWD uses an ARM CPU standard bi-directional wire protocol, defined in the ARM Debug Interface v5. This enables the debugger to become another AMBA bus master for access to system memory and peripheral or debug registers. The Debug Access Port (DAP) is split into two main control units.
What is SWD debugging?

Which MCUs have SWD interface of the following cores?
All the MCUs with SWD interface of the following cores : ARM7, ARM9, ARM11, Cortex-M0, Cortex-M3, Cortex-M4.
Where are the SWD interface pads located in WIO terminal?
For Wio Terminal, the SWD interface pads are on the bottom of the front side of Wio Terminal (Bare PCBA without casing). There are three jumper wires that need to be led out: Once the jumper wires are soldered on, we can connect them to the J-Link Debug programmer following the SWD Pin Map:
