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 available 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(see List of available command line options ), J-Link SWO
Viewer Cl can be directly started with parameters.
