Re: [gentoo-embedded] Some question about gentoo/openmoko

[Christoph Spielmann]

Hi! I can't answer your questions as i'm one of the cross-compilers but i do
have one question: You said you are using gentoo on the freerunner. Does
that mean you use it as the main OS (including phone related stuff)? Because
almost everybody had to give up (including myself yesterday) using Gentoo on
a daily basis because we all had troubles getting the phone-related stuff to
work reliably. The funny thing is that almost everybody faces different
problems (using shr i can call other ppl without problems but i can't answer
incoming calls and for dagger for example it's exactly the other way
around).

To answer one question: Well if the sheevaplug uses a arm4-softfloat
processor it should be possible to use it for native-compilation fir the
phone (i guess that's what you want to do) But i think it would be easier
just to get the gta02-devboard from openmoko as this has exaclty the same
hardware as the freerunner itself.

HTH,

Christoph
