Supported Debuggers and Tools
The usb
2
Demon is fully compatible with all of Macraigor’s software tools, including our
free OCD Commander debugger, free GNU toolkit distributions, OCD Flash Programmer
application, and our production line test tools.
In addition, several commercial third-party debuggers can interface to the usb
2
Demon. A
partial list of our debugger partners includes:
• Accelerated Technology/ Mentor Graphics
• Allant (ARM)
• Arc (Metaware)
• Altium
• DDC-I
• Green Hills Software
• IAR Systems
• Metrowerks
• Microcross
• Microsoft
• Paradigm Systems
• Red Hat
• Viosoft

Theory of Operation
The usb
2
Demon operates as a converter between the target JTAG/BDM signals and host
debugging commands. Power is supplied by the USB interface so that no external supply
is necessary. The buffers that interface to the target OCD signals are powered by the target
itself, allowing the usb
2
Demon to automatically match target voltages between 5.0 V and
2.2 V.

The usb
2
Demon is a BDM/JTAG interface used in the
design, debug, and programming of microprocessor
and microcontroller based embedded systems. One
side of the usb
2
Demon interfaces to a USB 1.1 or USB
2.0 port of a host PC and the other side connects to
an OCD (On-Chip Debug) port on the target system. As
with all Macraigor interface devices, the usb
2
Demon
can simultaneously debug up to 255 devices on a
single scan chain. In addition, up to 16 usb
2
Demons
can be connected to a single host machine.
The usb
2
Demon is designed to be a major upgrade
from the Wiggler series of OCD connections and, for
many targets, is also significantly faster than a Raven.
It supports configurable JTAG/BDM clock rates up tp
20 MHz .
The usb
2
Demon is compatible with Windows and Linux
hosts. Supported versions of Linux are Red Hat 7.2 – 9
and Fedora Core 2.
