Trion T20 FPGA Questions

A Couple HostMot2 / Efinix Trion FPGA questions.

• Is SPI a option or only Ethernet & PCI at present? I did not see a spi _efx.vhd but I may have over looked it. 
• Any reason a T20Q144C4 could not be used instead of the T20F256C4 with Hostmot2? I feel like I may be over looking something obvious for the sake of solderability while perusing the source files.

SPI should work though a Efinix specific top level file would need to be
made from the Xilinx source.  Efinix tools don't automatically
translate "Z" types into tristate pins so you have to export the signal
_and_ enable pins from the top level file. Note for the current SPI source
(GCSPI) The SPI clock must be routed to a FPGA clock pin.

Any package is OK

Thanks for the quick response, This should get me going in the right direction. Currently I have only gone so far as to generate new .bin files when required for my 7i92t/7i96s cards.

Awesome, glad to hear it.
