Hello, I am trying to send data from one SKARAB to another SKARAB over 40GbE. I have created two separate JASPER files, one for receiving and one for transmitting. Each design has one forty_gbe yellow block and are configured similar to Tutorial 2 on the casper website. In the JASPER file used for transmitting, I have placed a snapshot block on the tx_data signal for the forty_gbe block and am able to read the correct data from the snapshot block using casperfpga. While it appears that the correct data is being transmitted, nothing is received by the second SKARAB. In the JASPER file used for receiving data, I have a snapshot block on the rx_data signal, which should trigger once a valid frame is received. However, when I run fpga01.snapshots.snapshot2.print_snap(50) it just hangs, indicating nothing has been received.
I did notice that when I right click on the forty_gbe yellow block and go to Mask >> Edit Mask >> Parameters&Dialog, there is a menu that allows for the card slot location of the 40GbE card to be selected. Our SKARAB units have the 40GbE card populated on Mezzanine Slot 3, however only Card Slot 0 and 1 are available to be selected. Should this option be set to slot 3 in order to properly use the 40GbE ports? I should also mention that I have configured the tx_dest_ip block input to be 192.168.5.20 and the tx_dest_port to be 10000, which are the default values for the forty_gbe block. If there is anything else I should look at in order to properly configure the forty_gbe yellow blocks please advise.
