NIOS II中用FLASH programmer正确下载程序,但跑不起来的怪问题,请高手进来帮忙解决一
硬件系统:EP2C8 + EPCS4 + SDRAM + LED + LCD硬件背景:用Verilog写的代码,编译,AS方式把POF文件下载到EPCS4,关电,上电,运行正常---LED正常闪烁烁,LCD正常显示图形。(确定EPCS电路没问题)
软件系统:NIOS II
问题所在:Run as 模式下,LED正常闪烁,LCD也能正常显示图形。下载到EPCS4时,关电,上电,LED能正常闪烁,LCD却没显示了!
用FLASH programmer下载时,打印出来的息信如下:

请高手指点了,折腾了N天了。。。问题还没得到解决。。。 高人呀?你们都在哪里啊?出来救救我吧。。。 mark 你Nios的reset地址选的EPCS controller的吗?
估计你把它选在SDRAM里了 我也遇到了一样的问题,后来发现是因为NiosII(9.0)对我用的CycloneIII的支持有bug,换了8.1之后就可以了,不知这个能否对楼主有所帮助。。。可以到Altera的网站上看看。。。。 按3楼的说法检查 回复【楼主位】coolala584520
-----------------------------------------------------------------------
我也遇到了同样的问题, nios9.1sp2 nios9.0sp2我都尝试了,不能运行程序,但是能烧写,和楼主的一模一样
解决的话通知我一下,liming_nefu@126.com 回复【6楼】liming_nefu

我用flash programmer9.1把elf和sof一并下载到epcs里,复位后程序能跑以来,但一断电再上电就不行了,后来用jtag再加载一遍sof发现程序能跑起来,说明用sof2flash下载配置文件到epcs不好使,改用用8.0的就好用了。 我也碰到这问题啦,请问FLASH programmer下载是用jtag,还是用AS模式下载程序到epcs? 我用的是quartus 9.0。 有没有解决啊,回复一下 MARK! 我最近也遇到了类似的问题,不过我的是这样的EP3C10+onchip-ram+EPCS4。run as hardware 就行,下载到EPCS里面上电后就是没反应,后来发现时NIOS II IDE9.0本身的软件的flash program的bug,升级到9.0 SP2 就没问题了~!!! 有的大虾说是因为sof文件加了压缩的缘故 mark 原来大家都遇到了这个问题~我也同问! 我有些时候又是可以的!nios太不稳定了~BS 楼主 ,问题解决了么,我最近学习飓风3的,用niosII 9.0也遇到了这个问题 mark 学习 有时候行,有时候不行!!不知道为什么,正在检查 楼主你好 我也遇到类似问题了 你怎么解决的呢? 楼主你好 我也遇到类似问题了 你怎么解决的呢?
