I am using Nios2 dev kit(cyclone2), and quatus8.1, 

could rebuild sopc and compile example nios2 standard project successfully. 

but encountered the following problem when run sample application

Verifying 04000000 ( 0%) 

Verify failed between address 0x4000000 and 0x400FFFF 

Leaving target processor paused 

------------------------------------ 

I've found there is some post about verifi failed problem, 

but that seems because of customized H/W, 

I just used altera dev kit and sample project. 

so is it physical H/W problem? 

Could someone help me ? Thanks!
