Issue in running sample-app with intel flexran

[Rajisha]

Hi,

We are trying to run sample application of DU and RU following the link https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/Setup-Configuration_fh.html#a-1-setup-configuration.

While we are launching the application we are getting Error: "Loading file ./usecase/mu0_10mhz/ant_0.bin to DL IFFT IN IQ Samples in binary format: can't open file ./usecase/mu0_10mhz/ant_0.bin!".

We learnt from oran documentation on ODU-L that Octave software is required for generating IQ samples for that.

Can someone guide us on how to generate those samples using Octave and gen_test.m file.

icc version 19.1.2.254

dpdk version: 19.11

OS:CentOS Linux release 7.7.1908

Ok, now able to generate the IQ samples after installing Octave.

Tried running the sample-app,

./build/sample-app -c ./usecase/mu0_10mhz/config_file_o_du.dat -p 2 0000:17:02.1 0000:17:02.0

Hi Team,

Is there any input on this issue?

While running the sample-app, we are seeing below error.

EAL: Detected 128 lcore(s)
EAL: Detected 4 NUMA nodes

EAL: Multi-process socket /var/run/dpdk/wls_0/mp_socket

Is there any config issue? Are we missing anything?

and configured DU and RU on different servers.
