Feiling OK2 440 Development Board User Manual

About this manual

The document provides step‑by‑step instructions for operating the Linux system that comes pre‑installed on the OK2 440 development board. It covers booting Linux, setting the board to auto‑start, selecting the file system, switching between mouse and touch screen, transferring files via serial, mounting NFS, SD card and USB drive, using CMOS and USB cameras, setting the system clock, testing audio and network, and using web server, Telnet, FTP, auto‑run and abort functions.

A separate development tutorial section shows how to install Red Hat 9.0, add new users, create a cross‑compilation environment, compile and configure the kernel, build file systems, configure drivers (UART, USB, SD/MMC, camera, LED, RTC), and develop graphical applications with Qt. It also includes examples of GUI programming, threading, and driver experiments. This manual is written in Chinese.
