Hello,

I have instanced a generic sdram controller for a MicroBlaze on a Spartan 3. The problem is that the refresh is not functioning. The memory buss is totally quiescent except when reads or writes are occurring. Is there is some initialization command or signal I am overlooking.

Thanks,

Fayette

Are you sure the controller doesn't put the SDRAM into self-refresh mode between accesses ?
