Netdemo with Altera Cyclone V SoC development kit

[Adit Sahasrabudhe]

Just bumping this as I’m at a bit of a loss on it.

I’ve tried connecting the board to an Ixia traffic generator to send ARP requests, but the board does not respond. Additionally, the UDP traffic that the netdemo thinks it sends out is not seen at all at the other end. I feel like there is just some configuration of the driver that I am missing. I have tried the demo in loopback mode and it seems to be ok.

Thanks,
Adit

Subject: Netdemo with Altera Cyclone V SoC development kit

Hi,

I’m wondering if anyone has experience running the netdemo example on the Altera Cyclone V SoC development kit? The problem I’m having seems to be related to ARP tables, but I’m not quite sure.

My setup:
Host PC – Centos 6.6, using Eclipse to load and debug code. IP address of 192.168.0.5
Target board – Altera CV development kit, running netdemo example. IP address of 192.168.0.2 (see attached networkconfig.h file)

These systems are on a local network connected to each other via an ethernet switch, and are the only two devices attached. I have wireshark running on my host computer and it never sees any traffic from the device. The host is continually sending ARP requests that go unanswered. As a result, when I try to telnet or ping the device, I get the error “no route to host”. I can send the ‘u’ command to netdemo and it says it transmits UDP packets to 192.168.0.5, but again nothing shows up on wireshark. I have also attached the log from netdemo showing the ‘u’ and ’s’ commands.

Any insight is greatly appreciated.

Adit
