CX4-to-HSMC Adapter on Arria-II GX

I have ordered a couple of these adapters to be used with the Arria II GX kit as well. I shall find out soon... but I am wondering what you may be suspecting in terms of compatibility. Because, both the sides of the adapter are standard. i.e. hsmc and cx4. Are you thinking that the cx-4 pins may not be connected to the correct transceivers on the a2gx board?

I'm curious about how it works for you, too. I have a few of the adapters that I may want to use with new dev kit.

One quirk with the adapter was that the tx polarity was flipped so I had to force tx_invpolarity in FPGA design. Wondering if that's still the case with the adapter you got.

Thanks!
