Issue in launching sample-app with Intel Flexran

Hi Team,

 

We could launch Flexran sample-app on 2 different servers (one used as DU and another one as RU).

We followed this link: https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/Setup-Configuration_fh.html

and added probing and dpdk binding for the VFs on both servers.

But we don't see any Rx counter and the Rx IQ samples shows (0,0) only.

Can anyone help in capturing the packets while running sample-app?

Or is there any change required?

 

Thank you.
