9.1 The Debugger Menu Doesn’t Display
If the CDT370 board is connected inside the PC, refer to this page. If the
CDT370 board is connected through an RS-232 link, refer to page 9-3.
Add-on PC connection
1) If the screen displays nothing, follow normal troubleshooting procedures
and/or local repair procedures for the computer.
2) If the screen displays an error message when you invoke the debugger,
push the CDT370 reset button and try again.
3) Be sure there is no chip in the easy extract socket of the target connector.
4) If you are using a target system, disconnect the target connector from the
target system and try again. If it works with the target connector discon-
nected, see Section 9.3.
5) If the problem remains, be sure you invoke the proper communication port
and interrupt request line. Be sure also that the I/O address/IRQ used by
the CDT is not used by another card inside the PC.
6) Switch off your PC, remove the cover, and check that the CDT370’s config-
uration jumpers are correctly set and all components are firmly plugged
in their respective sockets.
7) If the CDT370 board seems to be well configured and you are using a tar-
get system, disconnect the target connector from the CDT 370 board and
try again. If the CDT370 works, the problem is linked to the target connec-
tor itself; see Section 9.3.
8) If all is OK and the debugger menu doesn’t display, please contact your
local Texas Instruments Distributor.
