Hi Andy,
Same issue here and you can probably find a set of emails form me in this list
that went unanswered. I spent quite some time debugging this just to find out
that apparently this is not supported. The issue in my opinion is that sofware
does not initialize the streamer for the second inp
Hi,
If your block is sending small amounts of bursty data the timeout being printed
is irrelevant as it just indicates no data has been sent for a given time lapse
not that no data has been received at all.

Hello,
I've implemented a DDS signal on the USRP device. In radio_legacy.v, I
input get_tx_I and get_tx_Q as my I and Q channels.
always @(posedge radio_clk) begin tx[31:16] <= (run_tx) ?
get_tx_I[31:16] : tx_idle[31:16]; // I channel tx[15:0] <= (run_tx) ?
get_tx_Q[31:16] : tx_idle[15:0]; //
Hi all,
After discussion on IRC and few questions (by Brian Padalino and Marcus
D. Leech), that made me not so sure about how I made the measurement, I
found the reason for frequency offset.
It wasn't fault of USRP B210 or broken cable providing 10MHz reference
signal. The issue was a bit more co
Hi all,
I am trying to create a custom RFNoC block with 2 inputs and 1 output. I have
attached my block code as well as the XML files for the UHD and GNU radio
integration. The block behaves as expected when I run the testbench. However,

We are in process of debugging an out of tree module that we created. It is
a source object that generates a given sequence.
We have compiled and loaded in our X310 device and all looks good. But when
we run it, we get no output.
Below is some of the output from the device.
Two questions:

Thank you for the follow up. Is this the only resolution?
Thank you

Hello Daniele Disco:
Unfortunately, at this time, the kernel driver for the PCIe Kit only
supports up to kernel 4.2, and you are using kernel 4.10. Would you be able
to downgrade you kernel, perhaps by using Ubuntu 14.04? We are working to
add support for newer kernels to the PCIe driver, but I do

With the X310 we have also taken the PCI-Express Connectivity Kit.

Dear All,
I'm sending OFDM frames in a bursty manner, i.e., a have slots of 1 ms with
14 OFDM symbols.
These 1 ms slots are transmitted from time to time and I'm using SOB and
EOB to make it a busrty transmission.
What I have noticed is that some samples at the beginning of the slot are
being mi
Dear All,
One question, when I send a packet to the USRP using a timed command, if
that packet is late (L) does the USRP transmit it or not?
We have been running some tests where it seems even when packets are late
(L) they are being transmitted.
What is the expected behavior when using timed tr
Hello Kau-Uwe,
You have to point your Makefile where the IP is located so that it can
build it for simulation. You can base this on the Makefile for the FIR
filter, for example [1], where the IP specific settings are introduced.
In your specific use case, it should be something like:

Hello Dixon,
Daniel's suggestion works, but that would mean adding a hard-coded path
into the fpga build system. It does the trick, but it is not recommended.
The OOT module has its own Makefile.srcs that intends to contain all the
HDL code that is required for the module. The procedure is the sa
