CPRI on stratix IV GT board

I'm trying to use CPRI IP core on a stratix IV GT board.Actually the supported device familys from the user guide do not include stratix IV GT. However, the similar stratix IV GX is included. but when I set the project device as stratix IV GT, I can generate CPRI core. Then I tried to set the project device as Max10, which absolutely does not support this IP core,I can't generate as I expected. The only problem is that I can't simulate my design under GT. So I only verified simulatoin under GX. When I tested my design on real board, I found that although the Interface response signal "waitrequeset" is functional, the CPRI CPU interface can not be read or written.And other CPRI functions like reset, 8b/10b ,RX status display are right. Now I just want to know whether the cpri core supports stratix iv gt.

One kind of warning that may matters is :

"Synthesized away the following RAM node"……

note that I got almost the same warning,and exact the same critical warning when I set the device as GX during compilation.

Here I attach the warnings during the compiling.

Thanks in advance!
