OpenOCD
OpenOCD JTAG server is a free on-chip debug solution for targets based on the ARM7, ARM9, Cortex-M3 and XSCALE family with Embedded-ICE (JTAG) facility. It enables source level debugging with the standard GNU Debugger gdb compiled for the ARM architecture. In addition internal and external FLASH memory programming is supported. Any GDBaware integrated development environment, e.g. Eclipse and Emacs, can benefit from OpenOCD.
“Free” means that it is licensed under the General Public License (GPL).
