OpenOCD is an ideal component for the GNU GCC toolchain for ARM processors. It can be controlled from the GNU debugger GDB and from a Telnet commandline interface. OpenOCD is capable of driving a variety of open JTAG hardware interfaces. One is the usbprog OpenOCD JTAG interface. It is licensed under the General Public License (GPL).
