Hi Jack,
Is it normal for the debug messages to say 'ICAP init FAIL'?
Unfortunately syslog is not very helpful either, here's a summary:
May 23 10:48:32 Antenna-PC dnsmasq-dhcp[29048]: DHCPDISCOVER(eth3)
00:40:89:41:13:02
May 23 10:48:32 Antenna-PC dnsmasq-dhcp[29048]: DHCPOFFER(eth3)
169.254.39.125 00:40:89:41:13:02
May 23 10:48:45 Antenna-PC dnsmasq-dhcp[29048]: DHCPDISCOVER(eth3)
00:40:89:41:13:02
May 23 10:48:45 Antenna-PC dnsmasq-dhcp[29048]: DHCPOFFER(eth3)
169.254.39.125 00:40:89:41:13:02
...
After some testing I can't see anything wrong with the NIC I'm using, same
for the DHCP server. I also compiled a modified golden image that used SFP
port 1 instead of port 0, but ran into the same problems.
I also noticed that the following debug message appears consistently 240
seconds after programming:
IP A9FE0313 NM FFFF0000 GW 00000000
TAPCP server ready
but there is no network traffic or logs suggesting that this IP was
obtained by the DHCP server. Nonetheless, I tried connecting to it using
this IP but had no success there either.
fpga = casperfpga.CasperFpga('169.254.3.19', port=69)
Thanks,
Jake Jones.
