DDR3 "verify fail" when applying little modifications in Qsys

Honored Contributor II

Hi , 


I have designed a NIOS II-e based system running on DDR3 memory and the system works fine but when I do small modifications in QSys (eg. add an interval timer) in some cases I face "verify failed" when programming NIOS2. 


My platform is Stratix IV Development Kit. NIOS II processor is connected to DDR3 controller reset and clock(afi_half_clock: 75Mhz).  


Thanks in advance

I'm having the same problem with DE4 board when using DDR2 memory for instrucion of NIOS. Could you solve the problem?
