Troubleshooting
6.1.1
General Procedure
If you experience problems with a SAM-ICE, follow the steps below to solve these problems:
1.
Close all running applications on your host system.
2.
Disconnect the SAM-ICE device from USB.
3.
Power-off target.
4.
Re-connect SAM-ICE to host system (attach USB cable).
5.
Power-on target.
6.
Try your target application again. It the problem disappears, you are done; otherwise continue.
7.
Close all applications running on your host system again.
8.
Disconnect the SAM-ICE device from USB.
9.
Power-off target.
10. Re-connect SAM-ICE to host system (attach USB cable).
11. Power-on target.
12. Start
JLink.exe
.
13. If
JLink.exe
reports the SAM-ICE serial number and the target processor’s core ID, the SAM-ICE
is working properly and cannot be the cause of your problem.
14. If
JLink.exe
is unable to read the target processor’s core ID, you should analyze the communica-
tion between your target and SAM-ICE with a logic analyzer or oscilloscope.
15. If your problem persists and you own an original SAM-ICE (not an OEM version), see
6.1.2
Typical Problem Scenarios
6.1.2.1
SAM-ICE LED is off
Meaning:
– The USB connection does not work.
Corrective action:
– Check the USB connection. Try to re-initialize SAM-ICE by disconnecting and reconnecting it.
Make sure that the connectors are firmly attached. Check the cable connections on your SAM-
ICE and the computer. If this does not solve the problem, please check if your cable is defective.
If the USB cable is ok, try a different PC.
