Invoking the Debugger
2-20
Note: You Cannot Use the –a and –p Options at the Same Time
the –a and –p options are mutually exclusive; only one can be used (accord-
ing to your hardware configuration)
.
If you used a wrong setting, you’ll see this error message when you try to in-
voke the debugger:
CANNOT INITIALIZE TARGET SYSTEM ! !
– Check I/O configuration
– Check cabling and target power
Entering the profiling environment (–profile option)
The –profile option allows you to bring up the debugger in a profiling environ-
ment so that you can collect statistics about code execution. Note that only a
subset of the base debugger features is available in the profiling environment.
Loading the symbol table only (–s option)
If you supply a filename when you invoke the debugger, you can use the –s
option to tell the debugger to load only the file’s symbol table (without the file’s
object code). This is similar to the debugger’s SLOAD command.
Identifying a new initialization file (–t option)
The –t option allows you to specify an initialization command file that will be
used instead of init.cmd. If –t is present on the command line, the file specified
by filename will be invoked as the command file instead of init.cmd.
Loading without the symbol table (–v option)
The –v option prevents the debugger from loading the entire symbol table
when you load an object file. The debugger loads only the global symbols and
later loads local symbols as it needs them. This speeds up the loading time and
consumes less memory space.
The –v option affects all loads, including those performed when you invoke the
debugger and those performed with the LOAD command within the debugger
environment.
Ignoring D_OPTIONS (–x option)
The –x option tells the debugger to ignore any information supplied with the
D_OPTIONS. For more information about D_OPTIONS, please refer to
Set-
ting up the environment variables in Section 2.6.
