One more piece of information. If in my device address list in Device3, I put
my 52.2 ip before the 42.2 ip, it seems to not die like before. This again
makes me think that it is grabbing things and randomly assigning which device
goes to which IP, yet something else has already the IPs, so it is a crap-shoot.

I needed to make some mods to your command, but it seems to have worked. Not
sure why it tried to list tx channels since I didn't request any, but it
doesn't seemed to have gotten in the way. I am guessing this points towards
your gr-ettus concerns.

I don't know for sure, but it might be possible to try:
benchmark_rate --args="addr0=...,addr1=..." --ref=external --sync=external
--rx_channels="0,1,2,3,4,5,6,7" --rx_rate=25e6
If this worked, it might show that the problem is in gr-ettus. But, you might
need to test the concept first using non-twinrx.

I'll check if fosphor is the issue, but it isn't for my non-twinrx test. I
currently have two X310s, dual receive, so 4 total receives, to a single host.
I had to much with settings to get it to work, but it certainly isn't an issue
in that setup.
I just double-checked and it isn't the fosphor block. I did notice that every
once in a while it actually seems to make connection (when I reduce my
throughput tremendously), but I don't see data. Without changing settings, I
would say it doesn't error out about 1/10 times. So I think there is some sort
of issue where it assigns IP addresses to the two devices, and then there is a
race condition with which one responds first....

If you use 2 X310 with non-TwinRx daughterboards, it can work with the same
flowgraph (including the fosphor block)? I ask because I am wondering if
there could be a bug in the fosphor block's handling of device number (either
gr-ettus or uhd).

That error at the end is usually what you see when you try to use a single
block twice without setting up the block select value. I have checked things
about 50 times, and I have everything setup right as device 1 and 2, and the
blocks (I started with a working flowgraph for non TwinRX X310s), but I keep
getting that error.
If feels like there is a UHD issue that when it is trying to setup which block
goes with which device, it thinks that there is only one device....

Perhaps run uhd_usrp_probe with --args="addr0=192.168.30.2,addr1=192.168.40.2"
and make sure that it is happy and shows you all of the blocks.

there could help me with the rfnoc side of things.

Rob,
I just figured it out (I found lots of people asking the question, but no
answers, so hopefully this can help someone else).
1st - Set the "device select" option to 0 and 1 for the different X310s
(usually you leave it at -1, but change the block select, but here we need to
mod it).
2nd - you need a single Device3 like usual
3rd - under the Device Arguments block, add in your two IP addresses using the
key of addr0 and addr1 like this: "addr0=192.168.30.2, addr1=192.168.40.2" (I
tried it both with and without the quotes and it works fine either way),
Now, Device 0 will get associated with addr0, and device 1 will get associates
with addr1.
I hope that makes sense and helps someone.

Hi Jason,
Given that under the hood, the stock multi_usrp (along with legacy_compat)
implements an RFNoC graph, it must be possible. I have run multiple X310s with
the stock multi_usrp. I have looked at legacy_compat pretty thoroughly and it
keeps track of blocks as a function of device number (motherboard). If I had a
2nd X310 handy, I would try it with my own non-stock multi_usrp object, but I
don't - sorry.

I can't seem to figure out a way to make it work, though I think there must be
a way. Both streams would be streaming to the same host machine for processing.
Thanks.
