Date: Sat, 31 Mar 2007 02:01:36 +0300 From: Oleksandr Tymoshenko <gonzo@xxxxxxxxxxxx> To: freebsd-mips@xxxxxxxxxxx, freebsd-embedded@xxxxxxxxxxx Subject: FreeBSD/MIPS project status update On behalf of FreeBSD/MIPS team I'm proud to announce that project has reached single-user stage. On the moment FreeBSD/MIPS runs only in malta board emulation mode of GXemul though adm5120 support is on it's way and people with real MIPS-based hardware can start playing with latest repo snapshot bringing FreeBSD on it. Many thanks to all who contributed with their time, efforts and experience. Especially to #bsdmips crowd for patience to newbies :) Attached mips.txt is a "recording" of sample GXemul session. Current p4 repo snapshot: http://kanar.ci0.org/mips2.tar.gz Check http://wiki.freebsd.org/FreeBSD/mips for sample build script P4 URL: http://perforce.freebsd.org/depotTreeBrowser.cgi?FSPC=//depot/projects/mips2/... -- gonzo GXemul 0.4.1 Copyright (C) 2003-2006 Anders Gavare Read the source code and/or documentation for other Copyright messages.
