Setting Up the Debugger Environment

Identifying the correct I/O switches
See your entries in Table 2 on page 5. If you did not modify the I/O switches,
skip this subsection.
If you modified the I/O switch settings, you must use the debugger’s –p option
to identify the I/O space that the EVM is using. You can do this each time you
invoke the debugger, or you can specify this information by using the
D_OPTIONS environment variable. Table 3 lists the I/O switch settings and
the appropriate line that you can add to the autoexec.bat file.
Table 3. Identifying I/O Address Space
Switch #
Address Range 1 2 Add This Line
0x0240–0x025F on on None needed. This is the default value.
0x0280–0x029F on off
SET D_OPTIONS=–p 280
0x0320–0x033F off on
SET D_OPTIONS=–p 320
0x0340–0x035F off off
SET D_OPTIONS=–p 340
Note: I/O Address Space
1) The ’C5x EVM uses 96 bytes of the PC I/O space.
2) If you did not note the I/O switch settings, you may use a trial-and-error
approach to find the correct –p setting. If you use the wrong setting, you
will see this error message when you try to invoke the debugger:
CANNOT INITIALIZE THE EVM ! !
