Infineon Debug Connector (16-pin)
The KIT_XMC4400_DC_V1 board supports
debugging via Infineon‟s device access server (DAS), when using
KIT_DRIVEMONI_USB_V2 as interface device. The latest release of DAS software can be downloaded from
. When using an external debugger, the on-board debugger has to be switched
off. This is done by connecting pin 6 to GNDISO. KIT_DRIVEMONI_USB_V2 already provides this connection
and the OBD is disabled as soon as the connector is plugged in.
Next to the SWD debug signals which are provided as unidirectional signals because of the galvanic isolation,
UART and CAN signals can be accessed through this connector as well. Figure 9 shows the pin assignment of
the connector, the following table lists the signals as well.
