I bought the 410-301(NetFPGA-SUME Virtex-7 FPGA Development Board)

As our pictures show：the board configured four 10G optical modules.
The driver of sume-riffa has been loaded, and we can see four network ports nf0~nf3 via lsconfig command.

The problem is we failed when we test the 10G loopback with the Github's Acceptance Test Project.

Anyone have good idea for it？

Are your connections like nf0-tx -> nf1-rx , nf0-rx <- nf1-tx and nf2-tx -> nf3-rx , nf2-rx <- nf3-tx ?

Is it a constant failure? meaning that out of 10 tries all of them are failing?

Have you checked the hardware test for the reference nic? Does it fail also?

Apparently you havent been granted access to the NetFPGA-SUME repo. Please register here first and then you can view the discussion.

Finally you should download the latest version (v1.10) of the source code in case you have an older one.

We download and run this script and got the log file(murugan.log).

We running below commands and got the log file (system.log) .

user@your-machine: sudo -i
root@your-machine:~# for i in {1..39}; do dmidecode -t $i >> system.log; done

murugan.log
system.log

Kindly note: our system is Ubuntu 18.04 rather than Ubuntu 14.04,16.04,20.04.

Our questions are:

  1. Can you finger out the problems according the log files?
  2. Does the version of the Ubuntu 18.04 affect the test results？

Can u view this discussion ?

  1. From the logs I cannot spot something unfortunately.
  2. If you have downloaded all the required libs and the correct python version, I believe u should not have any problem with 18.04
    Can you try to run the hardware tests for other reference projects? (like reference_nic, reference_switch )

In the loopback test. We successed when we test with 64kb test data. But we failed when we test with bigger data like 1600kb.

In addition, I‘m try to run the hardware tests for reference_nic. But it failed when we test loop back maxsize. Is it a hardware issue or a software issue?

Can you give some suggestions?
