Re: [ECOS] Ethernet driver question

["Jürgen Lambrecht" <J.Lambrecht@televic.com>]

I think the problem could be that your hardware driver has not been compiled.
If you are using an existing board supported by eCos, and are using the net template of the board, then it must be something else.

Can you better discribe all of it.

First try to make RedBoot running.
Enable all networking debugging and check it at the serial output.
To see all network options, look through your ecos.ecc file made at compilation:
- CYGPKG_NET_FREEBSD_LOGGING, CYGPKG_NET_DEBUG, CYGDBG_NET_SHOW_MBUFS; for debugging in general: CYGPKG_INFRA_DEBUG, CYGDBG_INFRA_DEBUG_TRACE_ASSERT_FANCY
- in redboot you can enable network debugging as an option with fconfig

Success,
