Update...
I figured it out. The conversation "Re: [USRP-users] GRC + RFNoC + Radio
Loopback" was kind of helpful.

Hi Jim,
try to add the file multTest.v (with the complete absolute path) in the
Makefile.srcs located at .../uhd/fpga-src/usrp3/top/x300/.
At least this worked for me.
Best regards,

Hi,
I am trying to figure out how to add additional Verilog code in a separate .v
file and have it build. For a simple proof-of-concept test, I started with the
"tutorial" module and the "gain" block, as per the instructions in the "Getting
Started" document. I then substituted this code in t
The mapping of channel to radio is a bit muddied. In most cases, each
channel will map to a different radio by default. The exception is
TwinRX. In that case, each pair of channels is mapped to a radio. And
yes, a stream command for multiple channels will duplicate the commands to
all radios.
Thanks again. Two more clarifications...
- When you say each "radio" has a separate queue, does that translate
into each "channel" has a separate queue? Assuming so, then I suppose a
streaming command that is for multiple channels will create an entry in
each of the queues.

Hi Rob,
Yes. The queue is a simple FIFO and does no reordering, so the commands
must be in time order. Each radio has a separate command queue, so they
will not interfere with each other.
All commands go to the same queue, whether timed or not, so care must be
taken with all commands issued to
Thanks Michael,
So, do all "timed" commands sent to the command queue need to be in
strictly ascending order (in time)? In other words, will a disordered
queue always produce a Late error or does it depend on how much disordered?
Are there any other "timed" commands to worry about besides the fol
Hi Rob,
Yes, that would be a problem. There is a single command queue for both TX
and RX commands to the radio, so something has to collate the T/R switching
commands with the RX streaming command so none of the commands arrive late.
Regards,
Michael

Hi Mark,
Update UHD to a newer version. The head of the maint branch or the latest
3.10.2.0 release should work. The ADC self test is skipped when supplying
"recover_mb_eeprom" as of UHD 3.10.0.0.

Michael

Just following up on the message I sent out 8 days ago. Does anyone have any
resolution to this issue? I have seen other people have the problem, but have
yet to find a fix.
Thanks

Hi ,
It would be great if any one could address this issue
I need to toggle between channels and collect data ,
by recreating the rx_streamer I am getting an assertion error.
I tried using rx_streamer.reset() but that didn't seem to destroy the
previous stream

Hello MarcusOkay. I gave your suggestions a try. Using Network manager, I
edited the existing connection settings, to manual, changed the the IP4
address to 192.168.10.3 and the netmask to 255.255.255.0 and left the gateway
address blank. After making these changes I restarted the VM and procee
Hello,
I apologize for my terrible English,
I have a problem with buffer overflow.
Tell me, please, what optimization measures do you use when working?
How the problem is observed:
I have 6 b205mini devices, and I noticed that I was up to a maximum of
205MHz per second. ie, either 5 devices on 41
The key issues was "square wave". Once that waveform is used, as opposed to
a sine wave, everything works as expected in a wider range of Vpp values.
Thanks,

I still haven't gotten anywhere with this. Can someone tell me if they've
gotten a B205 Mini working through Virtual Box with Ubuntu 16.04?
