USRP2 firmware and FPGA code for MIMO

Hi,

I’m trying to implement 2x2 MIMO systems using four USRP2s, two of which
are
connected by MIMO Cable and only one USRP2 is connected to computer
through
ethernet.

After I look through the related discussions and document on the
website. As
far as I know, the SD card for USRP2 connected to computer should be
loaded
with firmware and FPGA code as “master”. The other SD card for USRP2
connected with MIMO cable should loaded with other firmware and FPGA
code as
“Slave”. However, from the previous discussion
(OSDIR) , the
link
in that page is not found. I can not find the page to download related
files. Besides, I also find that there is some file like packet_router!?
is
necessary. But I still can not find the download page.

Does any one have any idea?
Please let me know.
Thanks.

Fisheep

Well, its implemented in uhd. No special images required. And it works
seamlessly in gr-uhd for gnuradio:
