This is based on work from: https://github.com/TheShed/OpenOCD-CMSIS-DAP/tree/cmsis-dap Main changes include moving over to using HIDAPI rather than libusb-1.0 and cleaning up to merge into master. Support for reset using srst has also been added. It has been tested on all the mbed boards as well as the Freedom board from Freescale. These boards only implement SWD mode, however JTAG mode has been tested with a Keil ULINK2 and a stm32 target - but requires a lot more work.

# 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...)
