本文基于Linux系统以及PC机与嵌入式Linux系统中的通信方式,详细讲述PC机上编译环境的建立、编译选项的配置、修改以及运行时的参数设置等。在此基础上,建立了主机和从机的联通环境,阐述了此环境下的工作状态,并通过串口将应用程序在向从机上移植的过程,分析了现有解决问题的方法。 This article is based on the Linux system and PC and embedded Linux system in the communication mode, detailing the establishment of the compiler environment on the PC, compiler options configuration, modify, and run-time parameter settings. On this basis, the establishment of the host and the slave of the Unicom environment, elaborates the working conditions in this environment, and through the serial port applications to the process of porting from the machine, analysis of the existing methods to solve the problem.
