A model of remote debugger supporting multiple types of connection

Software debugging plays an important role in the software development process. Traditional remote debuggers are allowed to use only serial port or ethernet connection to communicate with target. The data transfer rate of serial connection is slow. Ethernet connection needs ethernet card, but it is too large to be used on small embedded devices. For these reasons, we propose a model of remote debugger supporting multiple types of connection, such as serial port, ethernet, USB, Bluetooth and other debug channels to adapt to the diversity of embedded hardware environment. This model has better convenience, and the data transfer rate has been improved greatly than traditional remote debugger for embedded systems.
