Re: [openrisc] How to make ping work on or1ksim

[sip@delta.dk]

Hi,

I have done as suggested, but it still does not work. I have noticed
that the sim.cfg file found in orp/..../uClinux-2.0.x has parameters
not supported be the lastest or1ksim. Does anyone know for sure that
the ping is still working with the newest simulator, and if so, how
shall the sim.cfg look like and which options must be enabled/disabled
(besides --enable-ethphy) when configuring/compiling the or1ksim.

Soeren
