Timeline window—Interrupt Log graph

In this section:

What do you want to do?

The Interrupt Log graph displays interrupts collected by the trace system. In other words, the graph provides a graphical view of the interrupt events during the execution of your application.

Note

There is a limit on the number of saved logs. When this limit is exceeded, the oldest entries in the buffer are erased.

Requirements

One of these alternatives:

  • The C-SPY simulator. Not available for all cores and devices.

  • An I-jet or I-jet Trace in-circuit debugging probe, and an SWD interface between the debug probe and the target system

  • A J-Link or J-Trace debug probe with an SWD interface between the debug probe and the target system

  • An ST-LINK debug probe with an SWD interface between the debug probe and the target system

  • A TI XDS debug probe and an SWD interface between the debug probe and the target system

Display area

  • The label shown at the top left of the graph area displays the names of the interrupts.

  • The graph itself shows active interrupts as a thick horizontal bar where the white figure indicates the time spent in the interrupt. This graph is a graphical representation of the information in the Interrupt Log window, see Interrupt Log window.

At the bottom of the window, there is a common time axis that uses seconds as the time unit.
