Open On-Chip Debugger

The Open On-Chip Debugger OpenOCD aims to provide debugging, in-system programming and boundary-scan testing for embedded target devices. OpenOCD uses a “hardware interface dongle” to communicate with the JTAG IEEE 1149.1 compliant taps on your target board. OpenOCD currently supports many types of hardware dongles USB based, parallel port based, and other standalone boxes that run OpenOCD internally. It allows MIPS, ARM7, ARM9, XScale and Cortex based cores to be debugged via the GDB protocol. Flash writing is supported for external CFI compatible NOR flashes, NAND and several internal flashes.
