Hi all,
I was trying to run the ex_1layer example for neural networks on FPGA.
Although the flowgraph starts, I get a series of ''timeout on chan0" and
no output is produced.
Any suggestion?
Thanks,
Francesco
Below is my code:

Hi all,
I am trying to add the schmidlcox, fft and and eq to my X310.
Looks like the S&C block does not meet timing constraints. This is the
report from Vivado.
Any help would be much appreciated, thank you...

Hi guys,
I am responding to the following thread:
http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2018-August/057669.html
I am having the same problem while running the uhd_image_builder.py with
the default images for X310.
See below:

Dear all,
I am trying to load my customized firmware into an USRP N210. I have
tried the following but it defaults to the default image, regardless of
the input:
frank@frank-iMac:~$ uhd_image_loader
--args="type=usrp2,addr=192.168.10.2"
--fw-path="/opt/uhd/firmware/usrp2/build/usrp2p/usrp2p
Hi Marcus,
This is the output of the command:
frank@frank-iMac:~$ which uhd_image_loader
/opt/uhd_gnuradio_installs/bin/uhd_image_loader
And yes, the file should be ok:
frank@frank-iMac:/opt/uhd$ ls -la
/opt/uhd/firmware/usrp2/build/usrp2p/usrp2p_txrx_uhd.bin
-rwxr-xr-x 1 frank frank 16383 Se
Hi all,
I've built an N210 image using the source code provided by Ettus--
When I try to burn the FPGA image onto the N210, though, I receive the
following error:
frank@frank-iMac:~$ uhd_image_loader
--args="type=usrp2,addr=192.168.10.2" --no-fw
--fpga-path=/home/frank/u2plus.bit

Dear all,
I have some questions regarding the DDC implementation (ddc_chain.v, usrp2):
1) Why do we need two half-band filters (one large and one small) after the
CIC? What is their purpose? Can’t we use just one half-band?
2) What is the purpose of the scale factor multiplication after hb2? Wha
a function of the decimation (all of this because we're doing
fixpoint math). We try and negate this as much as possible by
multiplying the output with a compensation factor.
