Well, if you have configured the Sequential mode, I guess this is a
problem with the indexer of eclipse. Eclipse seems to not have found
the CYGIMP_LWIP_MODE_Sequential. I've had similar problems.
The way I currently work inside eclipse is to create a C/C++ project
using the 'build' directory as the projectss main directory (the
directory where you run ecosconfig).
Do you mean "as workspace"?
Create a new 'C Project' and select 'Makefile Project' -> 'Empty
Project'. Specify a project name and as the 'Location' use the build
directory where you have your ecos source tree.
Then I add the ecos repository as a
linked folder (I usually directly add the packages folder, as this is
There are several ways of doing this. What is the method of your
choice?
I understand your link in "path2ECOSroot"/packages ?
Exactly. Right click on the project you just created in the 'Project
Explorer' on the left. Then select 'New' -> 'Folder'. Enter a 'Folder
name' like 'ecos' and click the 'Advanced >>' button then select the
path of your ecos repository (or it's packages subfolder).
This is just the way I use eclipse with my eCos projects. I have my
sources split up in multiple ecos repositories, which I all add as
linked folders. Only drawback is that I you cannot use version control
on these folders. But I'm used to do this on the console anyway. Maybe
there are better ways of doing this?!?

Hi Simon
I did what I understood from your text - and it got messy. It seems I did
not understand correctly ;-).
Anyway, I reverted back to my own eclipse-methodology and also decided to
go for your most recent lwip-port
http://download.westlicht.ch/lwip-20090903.tar.gz (which Mandeep had
mentioned). And with this it looks much more promising.
Running the tcpecho.c program, I can see that the DHCP-server on our LAN
recognizes the board, even assigns it an address, but somehow the thing is
not really working. I have not sent any tcp-packages to the board yet, but
I get a lot of timeout errors in the debug output (see attachment). Only -
I do not understand why and what all this output means. Something seems to
be unconfigured yet and this then causes these timeouts? How to fix that?
Further: How do I send tcp-packet to port 7. Will a browser where I enter
192.168.0.10:7 send a tcp-package to port 7?
Thanks for help and regards
Robert
