Hi,
In case anyone finds this unresolved entry, I think I found the error I was
making, it probably had to do with thread handling. I would recommend
always creating a thread group (boost::thread_group tg), and then calling
two separate threads, one for RX

Hi Rob,
Thanks again for your response. Enabling UHD logging didn't give much more
information about my "No upstream blocks." message or about anything that
might give any clues to make the program work.
I'll attach my .cpp in this mail in case anyone sees anything off with it

Hi Jorge,
I don't immediately see what the problem is. I can tell you that it is
certainly possible to do what you are doing. You can do so with as few as
one rfnoc block or you can use a chain. I have done this often.
Typically, after I verify my custom rfnoc block with a testbench, I will

Hi Rob,
Thank you for your quick response. I'm sorry if I didn't specifically
mention that. I did connect the blocks calling the connect() function like
so:
uhd::rfnoc::graph::sptr txrx_graph = usrp3->create_graph("txrx");
usrp3->clear();
txrx_graph->connect(dmafifo_blockid, 0, gain_b
Hi Jorge,
I don't see any indication that you are calling the Connect() function to
connect the RFNoC blocks in the FPGA.

Hi Nick,
that would be great, thanks.

Haven't had time to look at it, but certainly you should be able to connect

I'll give it a shot in the next few days.

Hi Nick,
it is for a X300 type USRP.
Thanks for your reply,

AllI, I having another issue with this loopback implementation.
Using the Python code provided with radio Rx to radio TX or with fifos and
another block inbetween, the radios are not starting (Rx and TX lights off) for
master clock rates larger than 8 Msps. Sometimes I get lucky and it runs, buy
You have neglected to also modify gr-ettus to add these to the API.

Thank you for the code.
I have an E310 and we are using latest version of RFNOC Development and
these functions return an error:
stream_cmd=uhd.stream_cmd_t(uhd.stream_cmd_t.STREAM_MODE_START_CONTINUOUS)
#self.uhd_rfnoc_streamer_radio_0.issue_stream_cmd(stream_cmd)
self.uhd_rfnoc_
I got it working (lights now turn on), see the below code: not sure exactly
why this one works but hopefully someone will find it useful.

actually try this one.
I think I had the tx and rx mixed up. Neither still work though.

Thanks. At first blush this looks like it should work to me. I'll try it
out here.

You need to help us before we can help you. Can you tell me:
* What you're actually trying to do
* Your hardware setup
* Your UHD version
* Your flowgraph
* The results you expect
* The results you actually observe
Then maybe we can help.

I tried doing the changes in uhd, and gr-ettus. I also tried changing that
register value to 0 for the fpga and making a new e300.bit file.
Any recommendations on how to troubleshoot? Also as I referenced, I'm
doing this on a new e312 usrp.

It should still apply. Is there something specific you're having trouble
with?
