rapidio Gen1 and rapidio Gen2

Dear:

If i want to link two devices, one use rapdio Gen1(RapidIO Interconnect Specification,Revision 2.1) and the other use rapdio Gen2(the RapidIO v2.2 specification). can they work well?

I meet a problem, one device is TMS320C6455(The SRIO peripheral is compliant to V1.2 of the RapidIO Interconnect Specification), the other is Stratix V, if stratix V use gen1, They can establish the rapidio link and communicate each other, but if stratix V use gen2, they can not establish the link. Now i doubt the compatibility of altera rapdio core, who can give some clues to me?

Thank you very much.
