Hi
I added the packages CYGPKG_NET_LWIP v3_0 and CYGPKG_IO_ETH_DRIVERS v3_0
to my (proven) template, configured tcp and started the build. But hellas
- it runs on a severe problem:
<cut>

Does anybody know how to fix this problem? And what's about these
warnings? Thanks for help.

I got the same error once while trying to add lwIP to my SAM7X
template (using the GUI tool).
I started afresh and things worked! I also chose one of the
pre-defined configs i.e lwip_eth.

I am not so happy: The error persists. Any other hint?

Now it builds succesfully. It seems that the macro
CYGPKG_IO_ETH_DRIVERS_STAND_ALONE
was the problem. Disabling it and it worked. However, I do not understand
what this
macro does - or does not. Has anyone a hint what this "stand-alone" means
in this
context. Thank you.

In this context, "standalone" describes a TCP/IP stack which does not
use the eCos kernel. Such a stack might be provided by RedBoot or by
application code. The various eCos ethernet drivers will be built
without interrupt handlers if CYGPKG_IO_ETH_DRIVERS_STAND_ALONE is enabled.
