Some new discover : If a use only one of the two NIC I have on my
system, everything work fine. When using two NIC, interrupts all the
time, even if no network activity, even if doing nothing and ARP
response are not catch by network stack. So the problem is a conflict
between both interfaces. Here is my driver declaration (for the i386
platform), maybe something wrong there :

The previous post "[ECOS] Cannot sendto multicast using FreeBSD stack"
put me on the way!!
No IP packet are send, but ARP is done. But it seem that the stack
doesn't get the ARP reply witch is on the wire. When calling send(),
for the fist calls, send() return > 0, but with errno=2 (No such
entry) then send() return -1 wiht erron=364 (Host is down). Can this
be because I have 2 NIC that share the same interrupt ?
2008/1/10, Antoine Zen-Ruffinen <antoine.zen@gmail.com>:
Sorry for the preceding message that was not send to the list, little
mistake from me (cliqued "reply" and not "reply to all").
Yes my application print about DHCP transaction and it is ok. I have
added some prints in every driver function in order to trace what it
is doing. The output is interesting :
1) The NIC is making interrupts all the time
2) The network stack never call the send() function.
Here is the output :

Please keep your replies on the eCos list!
**EVERYONE** please get this straight. Replies made by me on the

just the interested party. Private email support consultation and

The target platform is an embed PC with NS dp83816 NIC. I've port the
eCos driver my self for the PC platform.
I configure eCos with the configtool, just using the template I made
and the "net" package.
No, I didn't run a standard eCos network test program. But I build an
redboot with this configuration. If I type ping -n 1000 -r 1 -h
192.168.165.18 (is my host PC) everything went fine !
This is only partly relevant - RedBoot uses a completely different
network stack than normal eCos applications. Also, RedBoot does
not use interrupts, which the eCos stacks rely on.
I know that nothing was send : 1 becose network activity led doesn't
blink, 2 I monitor network with Wireshark (Ethereal). the monitoring
trace show the TFTP exchange and the DHCP init but nothing more. It
look like this :

Did your eCos application print anything about the DHCP transaction?
I'm betting that it did not (which would imply you are having trouble
with receive interrupts from your driver)

Hi List folks,
I've a problem with the TCP/IP stack:
- I use TFTP to load my program in redboot. That work fine.
- My application start, call init_all_network_interfaces(), it do the
DHCP stuff. That work fine.
- Then I open a socket and try to send / receive data. No packet is even send.
Does someone has already seen such problem ?
Any idea ?
We'll need more data than this in order to help.
* What's the target platform?
* How did you configure eCos for your failing application?
* Have you run any of the standard eCos network test programs?
* How do you know nothing was sent? What sort of debugging
have you tried so far?
