Design and Implementation of Ethernet Communication Method Based on Embedded Debugger WangWenjie, LuanXin (College of Information Science and Engineering, Ocean University of China, Qingdao 266071) Abstract: This paper introduces how to debug embedded software by Ethernet interface in the embedded debugger. The network communication between the host computer and the board has been implemented. To study the Ethernet driver and network protocol is aimed at the embedded board S3C4510B, and the redundant part has been deleted. This implementation both insures the remote debugging by Ethernet and satisfies the request that the embedded system calls for the embedded resources. Key words: embedded board; network protocol; embedded debugger
