Actually no, I want the code that enables a single usrp to receive signals
on two daughterboards. Sorry about the confusion on that; I assumed the
"multi" in the filenames was referring to multiple daughterboards, I had
forgotten there's a multi-usrp capability as well.
The standard host and fpga code support multiple daughterboards as
long as they are sharing the same interp and decim rates.
For examples of this please take a look at
gnuradio-examples/python/multi-antenna/*
So, with that cleared up, can you verify which file specifically I should
load into Quartus? There is only one usrp_std.qpf project file in
usrp/fpga/toplevel/usrp_std
so it is unclear to me how to compile for the two-daughter board case as
opposed to the single. Do I need to configure something in the project
file for the two-daughterboard case?
There is nothing for you to do. The standard code supports two
daughterboards. On the fpga it's handled via the muxes implemented in the
FPGA. See http://gnuradio.org/trac/wiki/UsrpRfxDiagrams
thanks,

p.s.- on a positive note, at least my efforts to date have revealed what
updates the multi_usrp.qsf file needs to compile!
Thanks!
Eric
