[ECOS] Re: ppc-gdb-ecos-reboot question

[Bob <bobvrpf at gmail dot com>]

I found that it might be because that hdlcDrv::initIpIf is
reinitializing the ethernet port.

Do I have to take that ethernet init part off the downloaded file,
which is a standalone app.

Or there're other good work-around?

Thanks,

Bob
