General Settings

General Settings define the device's overall tracing behavior.

Target Driver Setup - Trace

  • Core Clock is the clock frequency the debugger uses to capture trace information from the target device if Use Core Clock is selected. This frequency must correspond to the system clock frequency in your target application, otherwise the captured data might not be valid.
  • Trace Enable defines whether tracing is turned on or off.
  • Specify a separate Trace Clock if it is not equal to the Core Clock. To be able to enter a value here, disable Use Core Clock.
  • Use Core Clock defines whether the core clock is used for tracing.

Note

  • Some applications start from RESET with a lower CPU Core Clock and switch to higher clock rate in the startup code. When debugging such applications, stop the program execution before the clock rate gets configured, and modify Core Clock to match the new clock rate. Use the menu Debug — Debug Settings..., or assign the new value to the VTREG CORE_CLK.
  • Pay attention to the messages displayed in the Status Bar.
