# 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...) if [catch {transport select}] { echo "Error: unable to select a session transport. Can't continue." shutdown } proc swj_newdap {chip tag args} { if [using_hla] { eval hla newtap $chip $tag $args } elseif [using_jtag] { eval jtag newtap $chip $tag $args } elseif [using_swd] { eval swd newdap $chip $tag $args } }
