[ECOS] Anyone have lwIP working under eCos?

[Andrew M Hoerter]

I'm trying to get the latest lwIP code from CVS to work with the latest
eCos from CVS, but I'm encountering what must be a pretty basic problem.

I've read the lwIP/eCos README included in the contrib directory within
the lwIP tree, and have successfully applied the single diff to
the eCos repository provided in that directory as well.

When I attempt to compile eCos (having created an appropriate config file,
created a tree, etc.), I get the following error:

/opt/ecos/ecos-cvs/packages/devs/eth/intel/i82559/current/src/if_i82559.c:
2619:4:#error Empty i82559 ethernet DSR is compiled. Is this what you want?

Looking at the file, it's obvious some glue is needed to allow lwIP to
receive Ethernet frames from the driver.  When you compile in the FreeBSD
stack with eCos, that glue code is included where this #error happens.
But I can't find any mention of how to include the appropriate code for
lwIP, or perhaps I'm just supposed to gin it up myself?

Surely someone out there has this working, and can point me in the right
direction?

Thanks.

that glue is in io/eth/current/src/lwip and should be included if you
configure your ecos.ecc for lwip & eth like this
#ecosconfig add net_drivers 
after adding lwip. When you add lwip before that it defaults to using
SLIP since no eth support is there without a warning.You need to unset
standalone io eth support which is needed for redboot.

Yes, I've done that.

Okay, I've ensured that both CYGPKG_LWIP_SLIP and
CYGPKG_IO_ETH_DRIVERS_STAND_ALONE are set to 0 in my config file.  I still
get the same empty DSR warning.

Perhaps my config file is just hosed for some reason, although I've tried
recreating from scratch several times.  Do you have a working one you
could send me, so I can isolate what part of my setup is at fault here?

Thanks for the help.
