Well, I've rebuilt and reloaded the FPGA image, and.... it works. Both
from the embedded and the host, including gnu-radio.
I presumably did nothing different, and used the same YAML as last
time. Of course, I must have done something in the middle that is
beyond me.
In my defense, the error was quite strange :)
Thank you for your time and your help.
Lautaro.
This whole time, I assumed you were using a factory FPGA image.

Hello Rob,
You are right, the UHD version running on the embedded is 4.1.0.4.
In any case, I don't quite get why the examples running on the
ettus don't work either.
If I run ./benchmark_rate --rx_rate 1e6 --tx_rate 1e6
--rx_channels 1 --tx_channels 0, I get:

On the other hand, If I include tx channel "1" in any way (2Tx 2Rx

The only message that is different between tests and calls my
attention is: "[WARNING] [MPM.RPCServer] A timeout event occured!"
Any ideas?
In the meantime I'll try to reload the file system and the default
FPGA image, I'll let you know if I've any news.
Thank you,
Lautaro.

Hi Lautaro,
When you run embedded, what is the version that runs? I am
wondering if your embedded file system (and also MPM version)
is old and does not match the UHD version 4.1.0.5 that you are
using on a host workstation. If this is the case, perhaps
reload the file system using "dd" (don't use bmaptool).
Another thought would be to try benchmark_rate with 2 channels
tx and 2 channels rx (at a slow rate) and see if the lights
come on.

Hi everyone,
I'm trying to run a simple example on an Ettus E310.
I'm using an E312 with UHD 4.1.0.5 and gnuradio v3.8.0.5.
Everything seems to work okay, but I can not manage to get
the second channel (TRX-B) to transmit anything. FYI: I
can receive from both channels RX-A and RX-B.
The problem came up when I tried to transmit something via
gnu-radio, changing the "subdev" arg to "A:1" instead of
leaving it blank as I normally do.
When I pressed start, everything seemed to compile fine,
but the GUI freezes (something that did not happen when
using TRX-A).
To see if gnu-radio was the problem, I logged in the
embedded linux and tried some uhd examples from
usr/lib/uhd/examples.
As expected, I ran ./tx_waveforms --rate 1e6 --freq 100e6
--subdev A:0 and the tx light turned on and I could see
something on my oscilloscope. Also, a few "LLLLL" appeared
on the console.
When I ran:
./tx_waveforms --rate 1e6 --freq 100e6 --subdev A:1,
everything looks the same but no light, no signal, and no
"LLLLL" are displayed on the console. Just the message
"press ctrl+C to stop streaming".
Any help would be very much appreciated.
Regards,
Lautaro.
