hi:the problem I meet while run the NIOSII ESD 10.0 sp1. verify failed between address 0xXX and 0xXX; the address belongs to the sdram,I have check my project to make sure the dq[15..0] is bir-director and the connection is solid and so on... the problem is still there. So, I want to ask if the custom component of SOPC is the reason or not ?? I have add a SOPC component written of my own,but the quartusII project compiled successfully. best regard
HiI had similar behaviour. It was the watchdog (of my own) which resets NIOS cpu. Please, describe more : You program the Flash ROM or you just download programm into RAM ?
