9-5 CDT370 Repair Guide
9.3 The Target System Doesn’t Respond
If the PC and CDT370 board work but the target system doesn’t respond, or
if a problem linked to the target connector causes the emulator to hang, follow
this procedure:
1) Check the target system power (must be on when you invoke the debug-
ger).
2) If OK, power off the target system, remove the target connector from target
system, and check for broken or bent pins.
3) If the problem remains, power off the target system and the CDT370. If an
add-on PC connection is used, power off the PC and remove the cover.
Then check that the target system cable is properly connected to the
CDT370 board. Refer to the Chapter 8.
4) Check that there is no short circuit or broken wire on the target connector.
5) Check the application hardware (look for short-circuit and supply prob-
lems).
6) If the problem remains, contact your local Texas Instruments Distributor.
