The Novena laptop is a reasonably priced laptop with an FPGA and a
stretch goal to supply an SDR board with every laptop. There are two
days left on their fundraising campaign. I think that some of you
might think this is pretty cool.

Hi David,
I tried everything you suggested, and here's what I got:
1) I don't see any new messages with dmesg on ROACH2 after the attempted
connection; maybe I did something wrong? I have never used dmesg before.
2) I

Thanks a lot for your help!

If the answer is that we need to set up netboot to boot via dhcp+tftp+nfs,
there is another constraint: we want our final system to make use of a

Hey guys,
I've got several designs where I consistently clock 512 64-bit samples into

tgtap does three things.
It resolves ARP, which is great.
It creates a tap interface, which is of dubious value. (Does anyone
know which packets received on 10gbe are passed along to the tap
interface? It better not be a lot of them, because there's no way

hi daniel h,
i suggest casper collaborators only use one of the operating systems
supported by xilinx. see the list of supported OS's at:

I think Daniel said that
Alternatively, putting:
mii-tool -A 100baseTx,10baseT eth0
in a startup script on the roach should do the job with much less fiddling.
(And whoever packages etch for the roach should add ethtool.)

Dear Roach
OpenOnload (openonload.org) claims to get remarkable numbers of
received frames per second from userspace. Have any of you tried it?
One of the supported NICs (Solarflare SFN4112F) is quite reasonably priced.

I've found the 10GbE transmit side to be very finnicky. I can get it
to work reliably if I manually reset it after loading the model and if
I don't rely on the tx_afull signal. I think what goes wrong is that
I see tx_afull, send end of frame, then start sending the next frame.

Sadly the list is out of date: some of the switches are no longer in
production. The XG700, for example, is great and cheap
We have two new lab machines running Fedora 13 64-bit. They both have
Xilinx 11.4 (I think). One has Matlab 2009b and one has 2010a. Both
seem to work (they build bof files OK).
What's supposed to break?

I haven't tried it on the ROACH, but we've had great results (i.e.
much better than 1 ms) with the IEEE Precision Time Protocol (using
ptpd, from ptpd.sourceforge.net). You might want to give that a try
before you resort to fancier solutions.
