Cortex-A8平台的μC／OS-Ⅱ及LwIP协议栈的移植与实现
TRANSPLANTATION AND REALISATION OF μC/OS-Ⅱ AND LwIP PROTOCOL STACK ON CORTEX-A8 PLATFORM
摘要
Abstract
We propose a scheme which realises the function of accessing to the Ethernet using embedded device with real-time operating system.Cortex-A8 platform of TMS320DM8168 DaVinciTM digital media processor launched by TI is used for the transplantation ofμC/OS-Ⅱand LwIP protocol stack and to implement the embedded TCP/IP network protocol.Through studying the core architecture structure of Cortex-A8,we elaborate on the key points of transplantation ofμC/OS-Ⅱand LwIP for Cortex-A8 and the implementation of LwIP efficient mailbox mechanism,and give some of the key codes.It is verified through the test of system multi-task scheduling and Web server function application that the transplanted operating system runs in order,and the network traffic is success.On embedded devices the embedded TCP/IP protocol has been realised,this makes the embedded real-time operating system device has the function of Ethernet access.关键词
