Hello,
We are attempting to run replay_samples_from_file example.
We run:
replay_samples_from_from_file --freq 1e9 --file ../test.dat
The program hangs:

Hello,
Using multi_usrp we were able to access our GPS data on X310 device. Using
RFNoc Device3 we can set clock and access time, is there a way to also
access GPS data?
Our system is written in C++. Please advise.
Thank you

Hello,
We have a custom RFNOC block that we have created. When we using
GNURadio/Python everything works fine. When follow the examples in
uhd/host/examples and generate an executable using C++, we get an error on
execution.
We noticed that on start up the python program has no issue locating

Hello,
We would like to repeatably stream a fixed number of data points (i.e. 4096

I suspect there are several ways that this can be optimized.

Hello,
On E310 with environment correctly set up, run: uhd_image_downloader (in
the instructions, it is assumed that you are not connected to Internet, so
an error is expected.
Your output should be:
UHD_IMAGES_DIR environment variable is set.
Default install location: /home/root/newinstall/
Can you try to specify image on command line.
Uhd_usrp_probe --args "fpga=__.bit"
Specify rfnoc E310 image.
If I remember correctly I had to always specify image.
Good luck

Hello,
I have used the first method multiple times with no issues.
Did you issue command or is your setup_env.sh file correctly configured.
You must run every time you get a new shell from E310:
source ./setup_env.sh
You may still be pointing at default version of GNU Radio installed on E310.
Thank you for the code.
I have an E310 and we are using latest version of RFNOC Development and

Hello Jose,
Based on the information you have posted I suspect it is an error in you
$ROOTDIR/rfnoc/blocks/$MODULE_NAME.xml file.
You may be reading a value before it has been initialized, look at
arguments section and make sure you are not reading a value before it has
been written.
Good luck.
Hello,
We have implemented in Python and it worked. Now we are trying to implement
the following code in CPP.
We would like to directly communicate with RFNOC in CPP. We have generated
the following code to implement RFNOC SIGGEN->DUC->RADIO.
When we enable SIGGEN the TX/RX will toggle, but we g
We are in process of debugging an out of tree module that we created. It is

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.

Hello,
We found two errors in the file:
1. samp_rate parameter is not defined.
2. There is an indention error. The lines with "self.$(id).set_arg("spp",

Thanks,

We have modified sig_gen module to create an OOT module and we are
