Hi All,

I was going to post my solution soon but was too busy. So,

Yes I was able to solve the issue. The problem was that since i was only using the Dq_dqs2_bidir IP to write data out so i was not using the Read_data_out lines coming to the core from dq_dqs2 IP.

So i added the following code to use the read_data lines and the error "RDEN not legally connected or configured" was not occuring anymore.

process(core_clk)

begin

if(rising_edge(core_clk) ) then

read_datacore <= read_data_out;

end if;

end process;

Hope it solves your problem too :)

Best regards
