Setting Up the Debugger Environment
9 Installing the EVM and the Debugger
Identifying directories that contain source files (D_SRC variable)
The debugger uses the D_SRC environment variable to name directories that
contain program source files The command for assigning the environment
variable is as follows:
SET D_SRC=
pathname1; pathname 2 . . .
Do not precede the equal sign with a space. The pathnames are directories
that contain program source files. You can separate pathnames with a semico-
lon or with blanks.
Setting default debugger options (D_OPTIONS variable)
You might find it useful to set default debugger options using the D_OPTIONS
environment variable. When you use D_OPTIONS, the debugger uses the op-
tions or input filenames that you specify every time you run the debugger. The
command for assigning the environment variable is as follows:
SET D_OPTIONS=[
object filename] [debugger options]
Do not precede the equal sign with a space. This tells the debugger to load the
specified object file and use the specified options each time you invoke the
debugger. These are the options that you can identify with D_OPTIONS:
Option Brief Description
–b[b] Select the screen size
–i pathname Identify additional directories for source files
–min Select the minimal debugging mode
–p port address Identify the port address (see Identifying the correct I/O
switches on page 10)
–profile Enter profiling environment
–s Load the symbol table only
–t filename Identify a new initialization file
–v Load without the symbol table
Note that you can override D_OPTIONS by invoking the debugger with the –x
option.
For more information about options, see the invocation instructions in the
TMS320C5x C Source Debugger User’s Guide.
