Debug interface
There are two debug interface options provided: the on-board OpenSDA circuit and an external ARM
Cortex JTAG connector. The ARM Cortex SWD connector (J19) is a standard 2x10-pin connector that
provides an external debugger cable access to the SWD interface of the KV311Z128VLH7P.
Alternatively, the on-board OpenSDA debug interface can be used to access the debug interface of the
KV311Z128VLH7P .
OpenSDA
An on-board K20DX128VFM5- based OpenSDA circuit provides a SWD debug interface to the
KV311Z128VLH7P. A standard USB-A male to micro-B male cable (provided) can be used for
debugging via the USB connector (CN1).
The OpenSDA interface also provides a USB to serial bridge. Drivers for the OpenSDA interface are
provided in the IDE you use. Updated Windows drivers and more utilities can be found online at
http://www.pemicro.com/opensda .
Cortex debug connector
The Cortex Debug connector is a 20-pin (0.05") connector providing access to the SWD signals
available on the KV11 device. If the OpenSDA is powered and J13 is used cutting the trace on J11
