Macraigor Systems is shipping a new USB2 debug interface, and has ported its proprietary on-chip debugging technology to Linux. This allows the company's Ethernet, parallel, and USB debugging interfaces to be used under Linux development hosts, through GNU toolchains available for a wide variety of processor… architectures, according to the company.

Macraigor says its “usb2Demon” works with on-chip debug interfaces that include JTAG, E-JTAG, OnCE, and COP, at Hi-Speed USB 2.0 transfer rates up to 480Mbit/sec, depending on the capabilities of the processor.

The company says the usb2demon debug interface incorporates proprietary on-chip debugging technology called “OCDemon,” and that a new port of OCDemon to Linux allows the use of Linux development hosts, in conjunction with its freely distributed GNU toolsets that include OCDemon drivers. A “LibRemote” download is also available for those wishing to use other GNU toolsets. Toolsets are available for ARM, MIPS, PowerPC, XScale, and other architectures.

Other Macraigor OCDemon debug interfaces said to support Linux development hosts include an Ethernet-based “mpDemon” model pictured at right, and a parallel-port based “Raven” model. The company also offers a USB1 interface called Wiggler, and a tiny USB sprite JTAG-to-USB converter.

Managing partner James MacGregor stated, “Macraigor Systems is committed to providing hardware and software JTAG debug interface solutions at the best price/performance point.”

Availability

The Macraigor usb2Demon starts at $750, and is currently available for 17- and 20-pin ARM7; 17- and 20-port Cirrus ARM7; Intel XScale; Freescale MPC603e, 7xx, and 82xx; and for Triscend A7. The Raven parallel port debug interface also costs $750. The mpDemon Ethernet debug interface is priced at $1,800.

In addition to GNU toolsets for Linux and Windows development hosts, Macraigor distributes sample applications aimed at helping users get started quickly, it says.
