If you experience problems with a SAM-ICE, follow the steps below to solve these problems:
Close all running applications on your host system.
Disconnect the SAM-ICE device from USB.
Power-off target.
Re-connect SAM-ICE to host system (attach USB cable).
Power-on target.
Try your target application again. If the problem disappears, you are done; otherwise, continue.
Close all applications running on your host system again.
Disconnect the SAM-ICE device from USB.
Power-off target.
Re-connect SAM-ICE to host system (attach USB cable).
Power-on target.
Start JLink.exe.
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.
If JLink.exe is unable to read the target processor’s core ID, you should analyze the communication between your target and SAM-ICE with a logic analyzer or oscilloscope.
If your problem persists and you own an original SAM-ICE (not an OEM version), see section Typical Problem Scenarios.
