+# OpenSDA is the on-board debugger, some boards have a CMSIS-DAP compatible
+# interface, other boards comes pre-flashed with a Segger J-Link compatible
+# firmware. The OpenSDA controller can be re-flashed to provide either of the two.
+# Both interfaces work with OpenOCD, but we need to tell which one we have on
+# our debugger.
