Is there any massively insurmountable reason that this project wouldn't work with a Trion T20 FPGA? I did notice that SRAM was mentioned in a previous post, does this require an external SRAM chip or does it use internal FPGA resources?

It should be possible since the HM2 source that supports the T20
is available. I would expect that the on-chip RAM is sufficient

I did notice that in litehm2.py there are imports for "M12L64322a" and "GENSDRPHY", though they do not appear to be used anywhere. I just wanted to confirm that they aren't required for functionality.

How do I use two 901T boards connected to the switch at the same time?
In addition to setting the IP address of the card 10.10.10.10 and 10.10.10.11 , how does the HAL know that it is the only IO pin

You load the driver with multiple ip addresses specified
The hal pins/parameters will have different board numbers.

Its also important with multiple cards to use the read-request function
so that the second card does not have wait for the first card to respond
before its read data request is sent.

Sorry for the late reply. Yes, the SDRAM is not used, only internal resources (BRAM).
