Comprehensive guide for using the Loongson 1B development board, covering hardware, Linux setup, bootloader, and application examples.
The Loongson 1B Development Board User Manual provides detailed information on the board's hardware resources, including CPU, memory, interfaces, and peripherals. It also explains how to set up a Linux development environment on a host PC, compile the PMON bootloader and Linux kernel, and flash them onto the board.
Additional sections cover application porting, a series of development experiments (e.g., ADC, PWM, networking), and extensive appendices with tool usage instructions such as Minicom, EJTAG, and NFS configuration. This manual is written in Chinese.
