The Open On-Chip Debugger (openocd) aims to provide debugging, in-system
programming and boundary-scan testing for embedded target devices. The
targets are interfaced using JTAG (IEEE 1149.1) compliant hardware, but
this may be extended to other connection types in the future.

Openocd currently supports Wiggler (clones), FTDI FT2232 based JTAG
interfaces, the Amontec JTAG Accelerator, and the Gateworks GW1602. It
allows ARM7 (ARM7TDMI and ARM720t), ARM9 (ARM920t, ARM922t, ARM926ej-s,
ARM966ej-s), XScale (PXA25x, IXP42x) and Cortex-M3 (Luminary Stellaris
LM3) based cores to be debugged.

Flash writing is supported for external CFI compatible flashes (Intel
and AMD/Spansion command set) and several internal flashes (LPC2000,
AT91SAM7, STR7x, STR9x, LM3). Preliminary support for using the
LPC3180's NAND flash controller is included.


On OpenBSD only parallel port connection is supported for now.
