The mpDemon from Macraigor Sytems provides the embedded system developer with a fast, flexible, yet cost-effective JTAG/BDM debugging connection to PowerPC targets. Host connection can be made via Ethernet, parallel port, or serial port. The mpDemon supports multiple devices on the scan chain and automatically senses target voltage down to 1.8V. The mpDemon provides setup menus via either serial or web interface and has built-in support for the GDB Remote protocol, allowing any GDB session to connect to it via Ethernet.

The mpDemon is compatible with Macraigor’s free OCD Commander debugger and free GDB distribution under both Windows and Linux operating systems. Many other third-party debuggers also support the mpDemon. See our web site for a list of debugger partners. The mpDemon can also be used for in-circuit Flash memory programming using the Macraigor OCD Flash Programmer application.
