The existing doc for "ft2232_layout evb_lm3s811" is unclear
and/or misleading ... can someone clarify?
Board docs say it supports JTAG in two modes.
- The one documented for OpenOCD is "pass through" ... the
EVM operates as a $49 (sez DigiKey) JTAG adapter without
TRST, SRST, or some other goodies.
- The one which is the main point of the board: nothing on
the 20-pin connector, so the ft2232 is used to debug the
Stellaris chip (Cortex M3 based).
My two questions: (a) are the current OpenOCD docs correct
to say that only the passthrough mode works?? (b) did the
engineers at Luminary ("now TI") do the sane thing and make
all their other EVBs use the same ft2232 layout ... is it
for some reason unique to this board?
