SAM-ICE LED is flashing at a high frequency
Meaning:
– SAM-ICE cannot be enumerated by the USB controller.
Most likely causes:
– a.) Another program is already using SAM-ICE.
– b.) The SAM-ICE USB driver does not work correctly.
Corrective action:
– a.) Close all running applications and try to reinitialize SAM-ICE by disconnecting and
reconnecting it.
– b.) If the LED blinks permanently, check the correct installation of the SAM-ICE USB driver.
Uninstall and reinstall the driver as shown in Section 3 .
SAM-ICE does not get any connection to the target
Most likely causes:
– a.) The JTAG cable is defective
– b.) The target hardware is defective
Corrective action:
– Follow the steps described in Section 6.1.1 .
Contacting Support
Before contacting support, assure that you have tried to solve your problem by following the steps out-
lined in section Section 6.1.1 . You may also try your SAM-ICE with another PC and, if possible, with
another target system to see if it works there. If the device functions correctly, the USB setup on the orig-
inal machine or your target hardware is the source of the problem, not SAM-ICE.
Make sure that you have the following information available for the support team:
A detailed description of the problem
SAM-ICE serial number
Output of JLink.exe if available
Your findings on the signal analysis
Information about your target hardware (processor, board etc.)
