Research And Implementation Of Embedded Debugger Communication Method Based On Ethernet

With the wide application of embedded system, its research has been more and more important. Its development is different from desktop software, which is in the way of Host/Client. Its crossed debugger is divided into the Host and the Client, which need to communicate in the debugging. At present the serial port communication is used widely because it is implemented simply and executed conveniently. But its intrinsic default, such as limited distance, slow velocity and bad anti-jamming, restrains the performance of debugger, which can not satisfy the Real-time need of embedded system. The way of Ethernet port can overcome the disadvantage of serial port. It can not only afford the steady and reliable data transmission, but also be better than the serial port on the side of distance and velocity.At present the Internet protocol has been very ripe. The Internet Engineer Committee has defined the Internet protocol criterion in the RFC files, which has been adopted widely as a standard. So the author puts forward a method based on Ethernet, and realizes the communication between the Host and Client via the Ethernet port.This paper introduces the trait of embedded hardware platform and software debugging, summarizes embedded Bootloader technique, and aimed at the hardware trait cuts down the redundant parts for achieving the hardware setting at the least cost of system resource. Based on this Bootloader, the author introduces the T-Monitor debugger function and its capability. This paper mainly studies and transplants the Internet protocol, and realizes the Ethernet communication module, which not only ensures the exact transmission of data and files, but also satisfies the request of embedded resource, which is a steady and efficient method.
