Contacting Support
Before contacting support, assure that you have tried to solve your problem by following the steps out-
lined in section
. 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.)
