Instruction Trace Window

The Instruction Trace Window shows the history of executed instructions. The window is:

  • Enabled for all non-Cortex-M processor-based devices when using the µVision Simulator. (Refer to Trace Data Window for Cortex-M processor-based devices.)
  • Enabled only for ARM devices when debugging on target hardware.
  • For non-ARM devices, use the Disassembly Window with similar features when debugging on hardware.

Instruction Trace buttonOpen the window from the toolbar or from the menu View – Trace - Instruction Trace Window. Enable the flag View – Trace - Enable Trace Recording.

Instruction Trace Menu

Instruction Trace Window

Where

Filter Allows selecting the following display modes:
  • Execution-Mixed shows the source code and the assembler code.
  • Execution-Asm shows the assembler code only.
  • Execution-Source shows the source code only.
Nr. Is a number reflecting the order of the executed instructions.
Address Is the memory address of the instruction.
Opcode Is the operation code.
Instruction Is the instruction itself. Can be the assembly or source code.

Double-click any row to jump to the source code and disassembly line that corresponds to the instruction.

Note

  • The window's look and feel might vary with the driver settings of the debugging environment.
  • Refer to Configure Cortex-M Devices for Tracing of the ULINKpro, ULINK2, or CMSIS-DAP manual when using target hardware.
