MIMO Blocks in GRC

I’m preparing to start some work on MIMO with my USRP N210’s and I’m
a little trouble. When I run the GRC my only two options under the UHD
heading are “UHD:USRP Source” and UHD:USRP Sink". My problem is, I’ve
on many forum posts where people say they are using the UHD MIMO USRP
blocks. I also see the files corresponding to that on the GNURadio
repository but I can’t seem to get my GRC to update so that they show up
the GRC. I apologize if this is a very simple task, but I’ve tried
the repo as a source in Ubuntu and tried downloading the files manually
nothing works. Any help is greatly appreciated, thanks in advance!

Install the latest gnuradio from the master branch. When configuring the
UHD source or sink block, set the reference source to MIMO Cable for one
of the motherboards. From the block’s perspective the MIMO cable isnt
special, its just another source of time and clock reference.

The UHD source and sink blocks have been “unified” so that there is no
longer a separate set of MIMO UHD source/sink blocks.

Configure all your channels (I think the current UHD source support 32
channels), configure the clocking regime, and away you go.
