Download zImage fatal error

Hello all,

I have question.

I connect two designs - nios2 and some part of fpga design for IF(radiofrequency) processing and after compilation, where i try to download the zImage, it finished with this report:

----------------------------------

--------------------------------------

Where is error ? From the first time, when i connect these designs, compilation finished with timing warning, but now it reports:

-----------------------------------------------------------------------+

; Ignored Timing Assignments ;

+---------------------------------------------------------------+

; Option ; Setting ; From ; To ; Entity Name ; Help ;

--------------------------------------------------------------+

; Cut Timing Path ; On ; * ; data_in_d1 ; std_2s180_reset_clk_domain_synch_module ; No timing path applicable to specified source and destination ;

--------------------------

Is it jtag error or timing constraints ?

Thank you for answer.
