Abstract

Communications between a device and a debugging system are effectuated by programming an ICE with a first logic set, which enables the ICE to establish communications with the device and determine a unique identifier thereof. The ICE communicates the device'"'"'s unique identifier back to a host computer. The host computer matches the unique identifier to a second logic set and a plug-in module. The host computer then programs the ICE with the second logic set and activates the plug-in module. The second logic set allow the ICE and the device to execute program instructions downloaded with the second logic set in lock-step fashion. The plug-in module allows the host computer to interact in the debugging process as necessary. This achieves flexibility, because any ICE may be programmed to communicate with any device.
