+# Luminary Micro Stellaris Evaluation Kits

+#
+# There are a number of evaluation kits for Stellaris Cortex-M3 chips.
+# Currently they all bundle FT2232 based debug support.  When that is
+# used (instead of an external adapter), use this config file in one
+# of these two modes:
+#
+# - Eval board debug ... debug of the Stellaris chip via port A.
+#
+# - Other board debug ... same thing, but the board acts as a debug
+#   adapter for another board (using a standard ARM JTAG connector).
+#   The Stellaris chip stays in reset.
+#
+# Those support both JTAG and SWD.  SWD is an ARM-only two-wire debug
+# protocol; in 2009, OpenOCD does not support SWD.
+#
+# Port B of the FT2232 chip is normally used as a serial link to the
+# Stellaris chip.  On most boards (but not older LM3S811 eval boards),
+# when SWD is used Port B may instead be used to read low-bandwidth
+# "SWO trace" data, including so-called "printf style" output from
+# firmware via the ITM module as well as profile data.
