工具：Quartus II
器件：EP4CE15F17C8
1.File->New Project Wizard：
2.点击两个Next，进入Family&Device Settings，选择器件
3.Finish，建立工程完毕，点击Tools->SOPC Builder，输入名字后，OK
4.修改clk_0为100MHz
5.component library中搜索nios，双击Nios II Processer
6.Finish
7.搜索epcs，双击epcs Serial。。。Finish
8.搜索sdram，双击sdram controller，配置如下，sdram芯片为H57V2562GTR
9.搜索sysid，双击system id，finish
10.搜索jtag，双击JTAG UART，finish。搜索timer，双击Interval timer，finish。
11.修改epcs和sdram基址：0x0000000,0x04000000
12.双击cpu_0，配置reset vector和exception vector。
13.修改各个模块的base地址，如图：
14.点击Generate
15.Generate成功。
16.File-New
17.save as nios.bdf，空白处双击，添加mynios kernel，OK
18.双击空白处：MegaWizard Plug-In Manager
19.设置时钟：
20.Finish，此时nios.bdf
21.分别右键模块，选择Generate Pins。。。在分别对引脚名字进行重新命名。
22.Assignments->Import Assignments，导入mynios.csv，这是之前编好的引脚配置信息：

编译时发现问题，NIOS II模块和工程名字一样引起冲突，打开Tools->SOPC Builder,打开之前的SOPC文件，Save as kernel.sopc，Generate。将mynios用kernel替换掉，如图：（另外将nios.bdf重新命名为mynios.bdf，与工程名保持一致）
23.Assignments->Device，选择Device and Pins Options，Dual-purpose中全部设置为regular IO：
24.编译整个工程，生成mynios.sof文件。Tools->NIOS II Software Build Tools for Eclipse,new->NIOS II Application and BSP from Template。选择SOPC information file，并给工程名字起名，template选择Hello uCOS II开始uCOS的工程建立：
25.finish。编译整个工程，Run as-> NIOS II Hardware。其中hello_ucosii.c：

* Description: *
* The following is a simple hello world program running MicroC/OS-II.The *
* purpose of the design is to be a very simple application that just *
* demonstrates MicroC/OS-II running on NIOS II.The design doesn't account*
* for issues such as checking system call return codes. etc. *
* *
* Requirements: *
* -Supported Example Hardware Platforms *
* Standard *
* Full Featured *
* Low Cost *
* -Supported Development Boards *
* Nios II Development Board, Stratix II Edition *
* Nios Development Board, Stratix Professional Edition *
* Nios Development Board, Stratix Edition *
* Nios Development Board, Cyclone Edition *
* -System Library Settings *
* RTOS Type - MicroC/OS-II *
* Periodic System Timer *
* -Know Issues *
* If this design is run on the ISS, terminal output will take several*
* minutes per iteration. *
