Design Linux embedded operating system for HZDJ Test Equipment of Main Break
Li Zhong-Qi (School of Electrical and Electronic engineering at East China Jiao tong University, Nanchang 330013 , China) Abstract: To design Linux embedded operating system for HZDJ Test Equipment of Main Break is introduced. Linux is a modern mature operating system with open source code and suitable to embedded field, which has steady kernel, powerful function, better features of hardware compatibility and software flexibility. In this system, the kernel of Linux-2.4.18-14 is used. The system mainly includes Grub boot loader, initialization programs, device files, uClibc lib files, MiniGUI and MySQL database, based on which the user programs are built.
