Hello,
There is a new version of Lwip stack coming out. Has anyone try it? Is there available eternetif.c file using XMC lib? Can someone share it? What are the plans to create some examples with this version by DAVE team?

I don't know, thats really confusing in the lwip-source.
But trust me, it is lwip2.0RC1, i downloaded it yesterday from their homepage( http://git.savannah.gnu.org/cgit/lwip.git/snapshot/STABLE-2_0_0_RC1.tar.gz )

why do you still have DHCP_BOUND in main() instead of DHCP_STATE_BOUND?

It seems that i never tested dhcp using lwip 2.0. You are right, it should be DHCP_STATE_BOUND.

The posted sources did not work out of the box for me. It did not establish a DHCP connection; in dhcp_start() I got an assert "netif is not up, old style port?".
Somewhere I found the hint that I must call "netif_set_up(&xnetif)" before "dhcp_start(&xnetif)". Using this I now can establish a DHCP connection and the XMC now is sending UDP packets.
My problem now is: I cannot ping the XMC board. What is missing?
Best regards
Lothar

The board is sending udp-packets at maximum speed, therefore, there is no time to answer ping packets. Try to comment out the udp-send functions.
Nevertheless, i think there is a second problem, because i observed, that the ping response times grow if i send continuously ping requests.

Did anybody tried email? It was working very well. But I suddenly when I came back to the last project. It nearly stopped working. Only 2 emails out of thousands of tests.
The SMTP protocol seems to run on my side to completeness. The server aspmx.l.google.com answers in between correctly to MCU. But the email does not arrive to gmail anymore.
Why can be wrong?

@shenj : no, I did not try.
@red : I used Your sources and set up a simple udp echo server. Now I can ping the board. When I fire UDP datagrams fastly (300us) to the board I am obviously loosing telegrams and after some time the board becomes unrewponsive - no ping possible any more.
Loosing telegrams does not worry me but the fact that high trafic load makes the board crash is quite worrying to me. Is that normal? Are You sure that there is no bug somewhere?
At a UDP request rate of 1ms all seems to work fine - but this is too slow for my purpose.
Do You have an idea?

I still use the LWIP 1.4.1, which is very stable.
