# ARM Debug Interface V5 (ADI_V5) utility

# ... Mostly for SWJ-DP (not SW-DP or JTAG-DP, since
|
|
# SW-DP and JTAG-DP targets don't need to switch based
|
|
# on which transport is active.
|
|
#
|
|
# declare a JTAG or SWD Debug Access Point (DAP)
|
|
# based on the transport in use with this session.
|
|
# You can't access JTAG ops when SWD is active, etc.
|
|
|
|
# params are currently what "jtag newtap" uses
|
|
# because OpenOCD internals are still strongly biased
|
|
# to JTAG .... but for SWD, "irlen" etc are ignored,
|
|
# and the internals work differently
|
|
|
|
# for now, ignore non-JTAG and non-SWD transports
|
|
# (e.g. initial flash programming via SPI or UART)
|
|
|
|
# split out "chip" and "tag" so we can someday handle
|
|
# them more uniformly irlen too...)
