Hi,
I'm looking to move a block to rfnoc implementation. We use GR3.9 and UHD
4.1.0.1 (hopefully even newer once B200 issues are rectified)
Going through github and ettus knowledge base, there does not seem to be
support for GR 3.9. The most recent branches are master (expected 🙂) and
maint-3.8-UH
Hi Tellrell,
Do not use the Xilinx SDK, only the Yocto one, i.e.
/usr/local/share/uhd/images/y/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi
You need to source the
"environment-setup-cortexa9t2hf-neon-oe-linux-gnueabi" file before cross
compiling. If you use cmake with building your application, yo
Hi Ivan,
I saw your other post. I think setting the SPP via stream args doesn't work
correctly. Try this instead:
spp = 1024
radio_block.set_properties(f"spp:0={spp}")
Also, if you are streaming over Ethernet (i.e. network mode), make sure
your MTU is set to 8000 on both the host and the E310.
Hello Ivan,
Are you steaming into the ARM processor / PS or are you streaming over the
network? Are you running a UHD app or using GNU Radio?

Thanks for both suggestions. I installed lm_sensors, and it seems to find
two of the temp sensors. Not sure which two, though:
# sensors
e31x_battery-virtual-0
Adapter: Virtual device
temp1: -273.0°C
e000b000ethernet00-mdio-0
Adapter: MDIO adapter
temp1:+28.0°C (crit = +1
Correction-- missed you said "outside of gnuradio." Basically everything below
minus gnuradio. if the sensors_lm package is available (as marcus stated),
parse that output or just manually parse the /sys or /proc (forgot which one)
file descriptor for the sensor when you find it.
Best of luck!
Concur on verifying-- that being said I know at least one of them (possibly
CPU) was available on the SG3 image a while back (I'm sure nothing much has
changed there but its been a while).
Then is would be very simple to write a simple custom GNURadio block (like
basically a command line script
Thanks for the reply, I'll go ahead and flash the whole SD.

How are you doing the steaming? Over what channel? Directly into the E310? I
don’t know what the MTU is of that channel but it would not surprise me if it
can’t handle larger packets.

Hi,
I try to set length of fft = 512 or 1024 for USRP E310 (RFNoC UHD 4),
but when the value is set I haven`t received the data. When the fft =
256 it`s work fine.
My graph looks like this:
0/Radio#0:0==>0/FFT#0:0
0/FFT#0:0==>0/SEP#0:0
Setup of my SEP is:
stream_endpoints:
ep0:
My approach would be to see if any of those sensors are understood by the
kernel lm_sensors subsystem.

I'm helping out on a project that's using an E310. Someone else is
doing the GNURadio code, but I need to read the temperature values
periodically (once every few seconds). My code will not be running in
GNURadio.
It looks like there are three temp sensors (Zynq, ADT7408, and the
AD9361).

Thank you, this is more or less what I needed. I did check the 5 example files,
but was missing the critical “get_mboard_sensor_names()" to understand what
sensors were available.
