About OpenOCD

OpenOCD is a 100% free software On-chip-debugger for commonly-found ARM JTAG probes such as wiggler, chamaeleon, jtag-key and others.

It provides a human-readable telnet interface for manually halting/resuming the target device, reading/writing registers and memory, etc.

In addition, it provides a RDI (remote debugger interface) on a TCP port. This interface can be used by gdb (the GNU Debugger).

The GTA01 development team uses OpenOCD with a wiggler compatible probe as their ICE solution.

Getting OpenOCD

Debian Package

We now have a Debian binary package of OpenOCD, available from Installing this package is the preferred method to install OpenOCD on your development machine like

dpkg --install openocd_82-1_i386.deb

Source Code

OpenOCD Revision 82 and later have been proven to work with our QT2410 and Neo1973 target board and wiggler as well as Amontect JTAGkey and JTAGkey tiny. You can e.g. check rev. 130 out of the OpenOCD subversion via

svn co -r 130


User:HaraldWelte has provided a openocd.cfg configuration file for use of OpenOCD with wiggler and the QT2410 target board.

Known Bugs

  • CP15 register read/write of ARM920T core not working

This has been reported upstream. Bugfix pending.

OpenOCD and Debug Board v2

If you wan to use OpenOCD with our Debug Board v2, and want to use the serial port simultaneously with OpenOCD, you need libftdi-0.8 or later. Chances are high that your distribution still ships an earlier version of libftdi, so you might want to download it from and build yourself.
