Hello,
I just updated my rfnoc workflow to UHD 4.0 this week. I've gone through the
process of creating an RFNoC block, building the corresponding FPGA image,
putting it on an E320 (had to upgrade MPM), and seeing the block is present
when executing uhd_usrp_probe. The problem is that the block

Several weeks ago I went through the tutorial for producing the example "gain"
block using rfnoc 3.8 and uhd 3.15. There were some bumps, but I did get that
working fine. For the past couple weeks, I've been working with UHD 4.0 and the
latest gr-ettus repo.
I posted a question a week o
xample (in-tree would be
easiest) to automatically include the DDC and then insert the command line
"block-id" optionally after the DDC.
- In my testbenches, I have occasionally seend CHDR error messages like you
mentioned and it seemed to solve them if I set "s_out_payload_tkeep=1&q
that you might not
need to modify the default example). I don't know a lot about the E320 so I'm
not really sure what control you have over the master clock rate (and
ultimately the radio output rate).

Hi Rob,
Per (https://files.ettus.com/manual/page_usrp_e3xx.html#e3xx_rasm_mender) I
used the following on an E320:
mender install /home/root/usrp_e320_fs.mender
I'm pretty sure I needed to add a force flag to it as well.

Hello,
I'm trying to add a Xilinx DDS to a custom RFNoC block (using UHD 4.0 and
associated gr-ettus repo). To do this, I started building the FPGA image using
the GUI option, stopped the build shortly after Vivado opened, and saved a
Vivado Project. Then, in Vivado I configured/added a Xilinx

Hello,
I have an E320 that I'm trying to get to auto-boot when power is applied (so
the button doesn't need pushed). I followed instructions here
(https://kb.ettus.com/E320_Getting_Started_Guide#Enable_Auto_Booting) to set
the autoboot flag, but it isn't working (not automatically booting when

I just setup an E320 with a 1Gbps SFP. I've updated the filesystem, FPGA load

and I created a gnuradio flowgraph and streamed samples ok. I did not test
throughput, though.
What concerns me is that when I conne

It's been a while since I did this, but I had issues bringing up the gui as
well. Here is a copy/paste of some notes I wrote for myself:
* Edit the file "$PREFIX/bin/rfnoc_image_builder".
* Find the line "gui=args.GUI" and change it to "GUI=args.GUI" and save it.
* Next, edit "$PREFI
Hi Mark,
I'm not sure if this is your problem, but I had a similar issue. After some
debugging, I found that for some reason, with the OOT RFNoC Block inserted, the
total size of the CHDR packet plus the Ethernet header that gets added on in
the FPGA would slightly exceed the MTU size (mine was
Hi Mark,
Yes, that is how I set spp in my flowgraph. I don't think this is the issue,
but The E320 Getting Started Guide says:
* Streaming via SFP0 at 1 Gb rates requires a MTU of 1500
* Streaming via SFP0 at 10 Gb rates requires a MTU of 8000
That is why I was using an MTU of 8000. May
