There are several different types of cables that are popular for hooking up to JTAG headers inside consumer electronic equipment. Most of these rely on a regular PC's parallel port to drive the JTAG signal lines. There are vendors of commercial JTAG cables that sell them at extravagent prices. For the home user or hobbyist, however, a better choice is usually to construct a cable at home from commonly available parts...Go

JTAG is a whole lot more than just programming of devices. It was designed to be used in test and qualification of systems down to the chip level. As such it can be used for debugging of Bootloaders, Drivers and other low level operations in embedded systems....Go

This is a parallel port JTAG Debugger circuit for Philips LPC2xxx ARM microcontrollers. I haven't built it yet - maybe there are still some bugs. It is intended to be backwards software compatible with "wiggler" JTAG debuggers. The circuit was originally based on Leon Heller's "wiggler" clone schematic, then tweaked by suggestions from the LPC2000 Yahoo Group members....Go
