Hi,

my core provider gave me another core wrapper. this solved the SDRAM problem for the moment. However he gave me no reason why it happened... :(

Thank you Michal and David anyway.

Best regards,
Raul Camaras

Hi Raul, If you have problem with memory, you should set constraints for memory controller. But anyway constrains on your IP should help too. Regards, Michal > > Hi Michal, > > thanks for your email.
