Hello Sir,

The DPRAM's type in DSP Builder is set to Auto but M512 can not be used for true dual port blocks. Only M4K and MRAMs got this ability. M512 can be set only in a simple dual port RAM mode. Anyway, thank you very much for your response, I'm now quite sure that i need to redesign my project. There is no simple solution.

Best Regards

Joel
