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.

# This is an example of how to do a cross-build of OpenOCD using pkg-config.
|
|
# Cross-building with pkg-config is deceptively hard and most guides and
|
|
# tutorials are incomplete or give bad advice. Some of the traps that are easy
|
|
# to fall in but handled by this script are:
|
|
#
|
|
# * Polluting search paths and flags with values from the build system.
|
|
# * Faulty pkg-config wrappers shipped with distribution packaged cross-
|
|
# toolchains.
|
|
# * Build failing because pkg-config discards some paths even though they are
|
|
# correctly listed in the .pc file.
|
|
# * Getting successfully built binaries that cannot find runtime data because
|
|
# paths refer to the build file system.
|
|
#
|
|
# This script is probably more useful as a reference than as a complete build
|
|
# tool but for some configurations it may be usable as-is. It only cross-
|
|
# builds libusb-1.0 from source, but the script can be extended to build other
|
|
# prerequisities in a similar manner.
|
|
#
|
|
# Usage:
|
|
# export LIBUSB1_SRC=/path/to/libusb-1.0
|
|
# export HIDAPI_SRC=/path/to/hidapi
|
|
# export OPENOCD_CONFIG="--enable-..."
|
|
# cd /work/dir
|
|
# /path/to/openocd/contrib/cross-build.sh <host-triplet>
|
|
#
|
|
# For static linking, a workaround is to
|
|
# export LIBUSB1_CONFIG="--enable-static --disable-shared"
|
|
#
|
|
# All the paths must not contain any spaces.
