Two DDR2 SDRAM controllers to do Ping Pong buffering

Hi,

I built two DDR2 SDRAM controllers to do Ping Pong buffering using MIG 2.1 .The device is virtex4FX60FF1152 and ISE

ver is 10.1. When it runs on device,one signal of controllers init_done  is high,while another always keep  low,that is one controller don't work at all.   Anybody  have same problem?

 

Thank you very much

Hello.

Have you checked both the controllers individually.

Whether the init_done pin for both goes high individually. 

Best of luck.
