Macraigor Raven Parallel Port Debug

Macraigor Raven Parallel Port Interface Debugging

The Raven is a BDM/JTAG interface used in the design, debug, and programming of microprocessor and microcontroller based embedded systems. One side of the Raven interfaces to the parallel 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 Raven can simultaneously debug up to 255 devices on a single scan chain.

Raven is designed to be a major upgrade from the Wiggler series of OCDconnections. It supports configurable JTAG clock rates between 60 KHz and 8 MHz. The Raven will perform best with those ports that are EPP (enhanced parallel port) compatible but will also work with most other parallel port modes. The Raven is compatible with Windows and Linux hosts. Supported versions of Linux are Red Hat 7.2-9 and Fedora Core 2.

Supported Debuggers and Tools

The Raven 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 interface to the Raven. 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 Raven operates as a parallel to JTAG/BDM and JTAG/BDM to parallel converter between OCD signals and host debugging commands. Power is supplied by an external five volt power supply. The buffers that interface to the target OCD signals are lowered by the target itself, allowing the Raven to automatically match target voltages between 5.0 V and 2.2 V.
