NetFPGA SUME Server Recommendation

[ashishkashinath]

Hey folks, Do you know of a compatible server configuration (motherboard with appropriate PCIe 3.0 support) with which we can install the NetFPGA SUME board. If you could tell us a link for a recent product we could buy, it would be great. The thread in digilent https://forum.digilentinc.com/topic/16243-netfpga-sume-server-recommendation/#comment-39284

Asking since we tried connecting the SUME to a Dell T630 server having a PCIe3.0 slot, which doesn't seem to detect the board in lspci or dmesg.

Update: The board seems to get detected on tty console when connecting a USB cable and logging in using minicom but Xilinx Vivado does not detect the board as a "Hardware Target".

Hi, in general: * the board in vivado should be detected via USB (JTAG) even if there is no PCIe connection. If the board is connected to your local computer this should work automatically in vivado. If it is connected to a remote server, you have to install xilinx hardware server there. * for PCIe: you have to: 1. load a working bitfile on the FPGA (which has a PCIe core, connected correctly) 2. restart the server (without powering off, otherwise the FPGA config is lost). 3. now you should see something in lspci I had a similar issue with an old computer (which had PCIe 3.0 ). However, only a 5 Gt/s configuration worked for me. Maybe you should try this. regards, Ralf

Thanks Ralf for the steps.
we were trying out the command : fpga -f reference_nic.bit to program the FPGA with the bitfile using the XMD tool.

But we get an error saying "cable is not connected to the host". (when in fact the SUME board is connected to the host on a PCIe3.0_G3 slot as well as is detected via the USB-UART in minicom)

We are using a Dell Poweredge T630 server with a 0NT78X motherboard having a PCIe3.0 slot.

Hi, Have you tried to open the hw-manager in vivado gui. So you see the board there?

Yes, we tried that, but the board does not get detected as a hardware target.

Here's a list of PC parts that we're using for CS344 at Stanford for reference.

If you're seeing the "cable is not connected to the host" error then I'd be suspicious that either: (1) the JTAG cable is not properly connected to the SUME board, (2) the JTAG cable itself is bad/incompatible, or (3) the JTAG connector on the SUME board is broken. (3) is the most cumbersome to repair. You can try looking for broken pins yourself and soldering them or you can submit an RMA to Digilent and ask them to repair for you.
