   8 # There are a number of evaluation kits for Stellaris Cortex-M3 chips.
   9 # Currently they all bundle ftdi based debug support.  When that is
  10 # used (instead of an external adapter), use this config file in one
  11 # of these two modes:
  12 #
  13 # - Eval board debug ... debug of the Stellaris chip via port A.
  14 #
  15 # - Other board debug ... same thing, but the board acts as a debug
  16 #   adapter for another board (using a standard ARM JTAG connector).
  17 #   The Stellaris chip stays in reset.
  18 #
  19 # Those support both JTAG and SWD.  SWD is an ARM-only two-wire debug
  20 # protocol; in 2009, OpenOCD does not support SWD.
  21 #
  22 # Port B of the ftdi chip is normally used as a serial link to the
  23 # Stellaris chip.  On most boards (but not older LM3S811 eval boards),
  24 # when SWD is used Port B may instead be used to read low-bandwidth
  25 # "SWO trace" data, including so-called "printf style" output from
  26 # firmware via the ITM module as well as profile data.
