# 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...)
proc swj_newdap {chip tag args} {
if {[using_jtag]} { eval jtag newtap $chip $tag $args }
if {[using_swd]} { eval swd newdap $chip $tag $args }
if {[string equal [transport select] "cmsis-dap"]} { eval cmsis-dap newdap $chip $tag $args }
}
