Serial Wire Debug Specification

Serial Wire Debug Bus description and SWD information. SWD in a Bus-based Debug and Trace Environment In Figure 1, the combined Serial Wire and JTAG Debug Port (SWJ-DP) is shown as the debug interface to a SOC. 1.1 Serial Wire Debug Serial Wire Debug (SWD). It is part of the ARM Debug Interface Specification v5 and is an alternative to JTAG. The physical layer of SWD. The Debug Adapter (ISA3) converts between the Ember JTAG and Serial Wire. • Program or debug EM35x applications using Serial Wire. And current specs.

Serial Wire Debug bus Description SWD bus: [Serial Wire Debug], defines a point-to-point two wire serial bus developed by ARM in 2004. In some cases the Serial Wire Debug uses the acronym [SW-DB] when referring to the Serial Wire Debug interface. SWD is designed to replace the normal 5-pin port with a clock and single bi-directional data pin, providing all the normal JTAG debug and test functionality. SWD avoids the need to use scan chains for debug. SWD uses an ARM standard bi-directional wire protocol, defined in the ARM Debug Interface, to pass data to and from the debugger and the target system.

The SWD bus is a standard interface for ARM-based devices. The new multi-drop SWD released in 2009 is fully backwards compatible with the previous version, retaining existing single point-to-point host equipment connections, and enables a device to power down completely while that device is not selected, reducing power consumption. Power Tools Pro 5.2 Download there. The ARM multi-drop SWD has been designed to be fully interoperable with the recently announced IEEE 1149.7 standard. Seems like the names Serial Wire Debug and Single Wire Debug are interchangeable.
