有人知道這可能是怎麼回事嗎?

==============================================================================

我拿以前在別台PC上做好的project直接下到fpga是沒問題的

可是只要重新compilation之後就會出現這個問題

我想...是不是tool本身出問題的機會比較大?

好吧...我的問題解決了...我自己回答...

最原本我是使用QII5.1, Nios II 5.1, MegaCore5.1

換電腦QII5.1, Nios II 5.0, MegaCore5.0 出問題...

最後全部裝5.1就好了...

晕，原来是q2和nios2不匹配。还从来没有装过不匹配的这两个。
