NIOS II 安装uclinux的硬件要求

Hardware requirements

You should start with a minimal system with only,

• Nios II f or s core, with hardware multiplier, (f-core suggested, s-core is slower).
• sdram (minimum requirement 8MB),
• one full featured timer,
• a jtag/serial uart

Note in Linux, irq 0 means auto-detected, so you must not use irq 0 for ANY devices, except for timer.

It is possible to use e-core, but it will be very very slow.

It is possible to run without hardware multiplier, but you will need some hack.

硬件要求

你开始一个最小系统仅仅需要：

1、NIOS II f 或者s 处理器，带硬件乘法器（建议使用NIOS II /f,使用NIOS II/s很慢）

2、最小8M的SDRAM

3、一个全功能的定时器

4、JTAG/UART

备注：在Linux中，中断0意味着自动辨识，所以你不能把中断0分配给任何器件，除了定时器。没有硬件乘法器运行LINUX是可能的，但你需要一些hack。
