Hello However, we are stuck in debugging the system: we think we are sending stuff properly, but we can not read anything from the python socket, coming from our roach 2 fpga. Try running tcpdump on the receiving PC. If you are using tgtap logic, you should see occasional arp traffic from the

We haven't actually used the 1GbE core at all at SKA-SA, but AFAIK, it's the same and tgtap should work out the box. Henno's actually the authoritative source for all things 1GbE. He might be able to offer more tomorrow. Jason On 21 Jan 2013, at 15:52, Marc Welz wrote: Hello A question
