Most of this patch updates documentation and comments for various Luminary boards, supporting two bug fixes by helping to make sense of the current mess: - Recent rev C lm3s811 eval boards didn't work. They must use the ICDI layout, which sets up some signals that the older boards didn't need. This is actually safe and appropriate for *all* recent boards ... so just make "luminary.cfg" use the ICDI layout. - "luminary-lm3s811.cfg", was previously unusable! No VID/PID; and the wrong vendor string. Make it work, but reserve it for older boards where the ICDI layout is wrong. - Default the LM3748 eval board to "luminary.cfg", like the other boards. If someone uses an external JTAG adapter, all boards will use the same workaround (override that default). The difference between the two FT2232 layouts is that eventually the EVB layout will fail cleanly when asked to enable SWO trace, but the ICDI layout will as cleanly be able to enable it. Folk using "luminary.cfg" with Rev B boards won't see anything going wrong until SWO support is (someday) added. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

# 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.
