I'm using UHD 4.0 and building an FPGA for the E320 USRP.
I'm trying to follow the guide for debugging FPGA images on the Ettus website
AN-121.
I'm using the rfnoc_image_builder command to build the image, and have added
the -g option to open the GUI during the build process: udd_image_builder
Just noticed that I'd put uhd_image_builder, I did of course mean
rfnoc_image_builder.
Still not having any luck with this, seems to just ignore the -g option.

If I remember correctly, I believe DPDK tries to dlopen() *everything*
in the directory specified by the dpdk_driver parameter
Hi Mark,
This is curious. If I recall, someone else was having trouble with -g, but
it worked for me last time I tried it. I will try it again to see if I can
reproduce anything. In the meantime, you can run rfnoc_image_builder and
make in separate steps. See if this works:

Actually, it is not there. I did a find on the entire root file system
and that file does not exist on the E310 device.

So, do a find on "ld-linux*"
Either the compile built for the wrong architecture, or your filesystem

Hi Aaron,
This did indeed help. Now I am able to run ONCE successfully. After that
I get an error. Same behavior on both systems. Not yet sure how to clear
the error. I played with dpdk_link_timeout and even tried resetting the

That command produced no results, either.
If I am following the instructions at

Hello,
Is there any way to get the PPS pulse from PS side (ARM) in the USRP N300? I
would like to know if the PPS is mapped through the /dev/pps or if it is
embedded into GPSDO module.
Thanks,
Roberto

Hi all,
I am trying to get to work a simple signal recorder with an USRP1 via USB.
With a bare metal installation I got no samples drop with fs=8MHz.
Now, with a VM and the USRP connected to the ESXI I need to go down to
fs=4MHz.
I was wondering whether somebody has tried this and knows how to
