+# Dangerous Prototypes - Bus Blaster (with KT-Link buffer)
+#
+# The Bus Blaster has a configurable buffer between the FTDI FT2232H
+# and the JTAG header which allows it to emulate various debugger
+# types. This config works with KT-Link compatible implementation from
+# https://github.com/bharrisau/busblaster and is SWD-enabled.
