Connecting a SAM-ICE to an Xplained Pro Board

Xplained Pro kits featuring a 10-pin 50mil debug connector can use external debug tools like SAM-ICE

™

or Atmel-ICE instead of the built-in EDBG. Devices using SWD interface on-board will have a connector

with the pinout compatible with the Cortex Debug Connector.

You can connect the SAM-ICE to the debug connector on an Xplained Pro using either an Atmel-ICE

adapter, SAM-ICE adapter, or a 10-pin 50-mil header to squid cable. When using a squid cable, see the

table and figures below for how to connect the SAM-ICE to the Xplained Pro board.
