If a Missing program code message is displayed in the trace, it means that the program was executed at addresses where no code image is available in the download file. The debugger needs a complete code image for the correct trace reconstruction. The code not reported in the download file or a self-modifying code cannot be traced.
To analyze which code is missing in the trace:
1. Click on the last valid trace frame before the Missing program code message. This will point to the belonging program point in the source or Disassembly Window.
2. Set a breakpoint there.
3. Run the program until the breakpoint is hit.
4. Step the program (F11) from that point on to see where the program goes.
