3.8 J-Link SWO Viewer
Free-of-charge utility for J-Link. Displays the terminal output of the target using the
SWO pin. The stimulus port(s) from which SWO data is received can be chosen by
using the port checkboxes 0 to 31. Can be used in parallel with a debugger or stand-
alone. This is especially useful when using debuggers which do not come with built-in
support for SWO such as most GDB / GDB+Eclipse based debug environments.
3.8.0.1 J-Link SWO Viewer CL
Command line-only version of SWO Viewer. All commands avaible for J-Link SWO
Viewer can be used with J-Link SWO Viewer Cl. Similar to the GUI Version,J-Link
SWO Viewer Cl asks for a device name or CPU clock speed at startup to be able to
calculate the correct SWO speed or to connect to a running J-Link GDB Server
Using the syntax given below(List of available command line options), you can
directly start J-Link SWO Viewer Cl with parameters.
