Abstract

The emergence of multi-core wireless sensor nodes brings a new opportunity to the popularity of wireless sensor networks. At the same time, there arises the question “How to effectively debug concurrent tasks on a multi-core wireless sensor node?” In this paper, based on the uClinux operating system, we design TMCD (Task-level Multi-Core Debugger), a remote task-level debugger to support embedded multi-core programming. TMCD is an improvement of GDB (GNU Project Debugger). It can not only distribute multiple processes or threads among multiple cores, but also obtain the real-time information of each core and the debugee. We utilize TMCD on a dual-core platform. It shows that TMCD can effectively support multi-core programming.
