uCOS 在 NIOS II 上的移植

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:

下载地址:http://download.csdn.net/detail/wu20093346/8205265

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:
