5.2 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.
| Squid Cable pin | SAM-ICE pin |
|---|---|
| 1 (VCC) | 1 (VTref) |
| 2 (SWDIO/TMS) | 7 (TMS) |
| 3 (GND) | 4 (GND) |
| 4 (SWCLK/TCK) | 9 (TCK) |
| 5 (GND) | 6 (GND) |
| 6 (SWO/TDO) | 13 (TDO) (1) |
| 7 (Not used) | |
| 8 (Not used) | |
| 9 (Not used) | |
| 10 (RESET) | 15 (RESET) |
Note:
- Optional, if the device has this functionality.
Important:
If contention with the on-board EDBG occur, power the Xplained Pro board from another input like the external power header or from the target USB. Physically removing the connection between the EDBG and the debug header by removing 0Ω resistors, where available, or cutting the tracks to the EDBG can also be done.
