- #
- # There are a number of evaluation kits for Stellaris Cortex-M3 chips.
- # Currently they all bundle ftdi 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 ftdi 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.
