OFDM reference design nomac.bit not working

I removed radio boards in slot 1 and 4 from WARP v2 kits and only keep those radio boards in slots 2 and 3.

I setup the IP of host PCs connected to WARP as 10.0.0.200 and 10.0.0.201. They are still not able to ping each other.

Please help!

Something I observed:

1. After I wrote the nomac.bit image to WARP, radio board in slot 2 has a yellow LED while radio board in slot 3 has all red LED.
2. The two host PC can ping each other directly with ethernet cable connection.
3. I can see the green LED blinking near to ethernet port when I ping from host PC which means WARP receive packets from the host PC.
4. In another post, I read that radio in slot 2 is transmitting if I ping from the host PC. I can observe the very week green LED blink near the yellow LED also. D10, D13, D18, D20 never blink.

5. I tried both reference design 18.0 and 16.1. Ping does not work for both design.
However, I tried dummy mode on 16.1 and found the receiver is receiving packets. D10 and D13 are always green while d18 and D20 green alternatively.
18.1 Dummy mode is disabled.


Thanks.

Re: OFDM reference design nomac.bit not working

Update.

I have OFDM reference design 18.0 working now.
What I have did is I have one WARP board changed (when tested with 16.1 dummy mode, it's not working properly) and also I moved the two WARPs closer (1m)
Previously, i put them around 6m away from each other.

OFDM reference design 16.1 pinging still not working.
