Hello sir/madam,
I am working with a warp v3 and using WARPLab_Reference_Design_7.3.0._I downloaded the W3_WARPLab_7.3.0_2RF.bit bitstream and board hex display is showing <01>.Before that i have set MTU setting of my PC to maximum.This is 1432+28 =1460.I was trying to do Ping Max Payload Test.I set ip address of my PC to 10.0.0.1(and i tried with 10.0.0.200 also) I tried to ping the board by using command ping -l 8000 10.0.0.1.but I can not ping the board.I am no getting reply from board.Please help me for this problem.
I am using,
Windows 7,64 bit PC and i directly connected ethernet cable to board from my PC.
Thank you....

Sending a ping of 8000 bytes when your MTU is only 1460 will cause IP fragmentation, which the IP stack on WARP used by WARPLab does not support. Do normal sized pings work when you just try "ping 10.0.0.1"?

The issue is that the host IP address in the wl_setup script should be the same IP address as your host machine.
The warning:
Warning: No interface found. Please ensure that your network interface is connected
and configured with static IP 10.0.0.250
> In wl_setup at 306
is very important b/c WARPLab could not find a network interface which it could use. If you change the IP address of the PC to 10.0.0.250, then it should work.
One other thing to test is that you are able to successfully ping your node from the command prompt before running wl_initNodes in Matlab. Sometimes when messing around with IP addresses, the ARP table can get out of sync. From the command prompt, you can run "arp-a" to see the ARP table. It should look something like:
C:\Users\mango>arp -a Interface: 10.0.0.250 --- 0xb Internet Address Physical Address Type 10.0.0.1 40-d8-55-04-22-aa dynamic 10.0.0.255 ff-ff-ff-ff-ff-ff static ...

Thanks for your reply...
I followed the procedure you have mentioned,I set my PC ip adrress to 10.0.0.250.So host IP address in the wl_setup(10.0.0.250) script become same IP address of my PC,but if ping the node,it is not successful.I am using only one warp v3 node,i directly connected node to my PC (windows 7,64 bit with matlab 2011a and xilinx 13.4 installed) by ethernet cable.The PC is having inbuilt RJ45 Ethernet network port.
I have set DIP switch to 0000 and downloaded W3_WARPLab_7.3.0_2RF.bit bitstream,the hex display of node is displaying 01.
The result of ping will be look like this,

Can you try going through a gigabit Ethernet switch rather than directly? It's possible that your computer isn't implementing automatic crossover needed for direct connection like that. Also, just to verify, your computer has a gigabit Ethernet NIC correct? If it's running Windows 7 64-bit, I'm sure it does, but I'm just making sure. If for some reason it's only 100Mbps, then you'd have to change the C-Code in WARPLab to reduce the Ethernet speed in that design.

Thanks for your reply..
I am using WARPLab7.How to modify it for 100Mbps ethernet switch..?
and one more question..
Open firewall for UDP ports (10000 and [9000:9000+numNodes-1]) what it means...?(I have seen this line in PC requirements of warp site)
Thank you...

Changing the Ethernet link speed requires:
-Downloading the reference design archive
-Launching the Xilinx SDK to the SDK_Workspace in the reference design
-Importing the provided SDK projects
-Editing wl_transport.h to change WL_ETH_A_SPEED to 100
-Compiling the updated software and configuring the WARP node with your updated bitstream
However I would strongly encourage using 1Gb Ethernet. You will achieve much better performance with WARPLab over a 1Gb link than 100Mb.
Offline
Thank you so much for your reply...
I have tried with 1Gb Ethernet switch...everything is working fine(SISO,MIMO) with 2 warp v3 nodes.But i want implement SISO and MIMO with only one node.Please tell me, which file(code) of WARPLab_Reference_Design_7.3.0 i have to modify..
kindly oblige...
Offline
If you start with the Examples section of WARPLab ( http://warpproject.org/trac/wiki/WARPLab/Examples ). It is pretty straight forward to modify the SISO example ( http://warpproject.org/trac/browser/Res … iso_txrx.m ) to use the two RF interfaces on one node vs one RF interface on two nodes (ie you make the RX and TX nodes the same node and make sure the RF TX/RX interfaces use RFA and RFB respectively).
Similarly, if you have a 4 radio node (i.e. a WARP kit plus a [http://mangocomm.com/products/modules/fmc-rf-2x245 FMC radio board]), you could modify the MIMO example ( http://warpproject.org/trac/browser/Res … imo_txrx.m ) to use RFA & RFB to transmit and RFC & RFD to receive.
The main thing is to be carful with is connecting the RF interfaces together. Please refer to the WARP Hardware User's Guide: http://warpproject.org/trac/wiki/Hardwa … /WARPv3/RF for more details on the RF interface. Please note the last sentence: "To connect two WARP v3 kits via a coax cable, ensure there is at lest 40dB series attenuation." If you do not have attenuation, you may damage the RF interface.

Hello sir/madam,
I want to clarify one thing about WARP V3.
Can WARP V3 provide the capability to upconvert the baseband signal to RF Frequencies ?
Offline
Hi,
I face some problem related to WARP V3 hardware.
When I try to program the WARP v3 board with .bit file of WARPLab reference design I got the following error in terminal.

Both the LED of RF A is continuously blinking and LED display have the value E2.
what is this error ?Is it some damage of the Radio controller?

Unfortunately, that error message means there is a hardware problem. To start the RMA process, please contact Mango support via email at support[at]mangocomm.com.
