MON251 User's Guide

Restrictions

There are a few restrictions to using the MON51 Monitor to debug your target programs.

• All programs to be debugged must be located in RAM space. This is because breakpoints are set by replacing instructions in your program with an TRAP instruction. This operation, while completely transparent, may affect the operation of your target program.
• The memory mapping of a CPU board with MON251 is selected with hardware components and the Monitor configuration file. It is not possible to use Debug — Memory Map to change the memory mapping of the target system.
• The Performance Analyzer, Call Stack, Code Coverage, and Step Out capabilities are not available.
• The View — Periodic Window Update option is not available.
• Breakpoint Options are handled directly by MON251. However, when access or conditional breakpoints are set, the application is executed in single steps and not in real time. Single-step execution is at least 1,000 times slower then real time execution.
