结果SOPC里面的器件型号没改过来,改完一些之后还是有版本不匹配的问题。

本来我认为默认的Timestamp是1445258994,实际上要改为1445258956
其实:1445258994(13:51:51 2015/10/19),实际上要改为1445258956(23:44:34 2012/03/27)

网上说这是由于相移的原因。这个地址是属于sdaram的,重新编辑sdaram参数没有异常,判断那应该是osh.tcl文件分配地址有问题,打开osh.tcl发现分配地址没有重复问题。
网上解决方案:http://www.amobbs.com/thread-5476091-1-1.html
果然,由于osh.tcl中是S_NCAS,而工程中是S_nCAS,管脚没有绑定。然而这个问题并没有排除。
然后又搜了一些解决办法:
1,检查cpu地址是否设置的正确;
2,检查你的SDRAM(或SRAM)数据口确实用的是双向,而不是OUTPUT;(重要)
3,pll的相位差是否设置正确,一般会设在-45度---(-60度)。

想起当初修改内核的时候一直是未更新。

这是由于我直接在IDE下建工程烧进去造成的,重新再Quartus中编译一下,下载,然后Run As就成功了,出现以下代码:
nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0
nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)
Hello from Nios II!
这时候查阅到的Timestamp是1445308947。
总结:Timestamp时间戳不匹配,去Quartus II中重新编译一遍下载。
