Hi guys,when I used BF609 with DDR2(MT47H64M16),I had made a  mistake , I forgot to connect the signal of DMC_UDQS_n,DMC_LDQS_n,DMC_UDM,DMC_LDM to DDR2 the relevant pin.

 

I had found that setting  the EMR1.bit 10=1'b1 and MSK.bit9=1'b1 could solve the problem of  disconnection of DMC_UDQS_n and DMC_LDQS_n.

 

Is there any way to slove the problem of disconnection of DMC_UDM and DMC_LDM? 

 

Thanks for your attention!
