A few days ago I posted about some success booting my ip28 AKA Indigo2 R10000 Impact Ready. A updated version of the bootlog is appended. Used Tools: - CVS binutils, hacked to allow assembly and linking of 64bit non-pic executables. - GCC snapshot as of 2001-05-01 with some patch by Ralf to work better for R10000 and one more by myself. - CVS linux from oss, patched to recognize an ip28 and to work in a real 64bit address space. The Patches are available at http://www.csv.ica.uni-stuttgart.de/homes/ths/linux-mips/src The script I use to crosscompile is at http://www.csv.ica.uni-stuttgart.de/homes/ths/linux-mips/edit Current State: The Kernel boots via bootp/tftp/nfs into an initshell, execution of not too complex programs may or may not succeed, it's pretty at random. /sbin/init itself seems to run, too, but all(?) spawned processes crash due to unaligned access/illegal instruction in kernel space. The serial console drops characters on high throughput. If you want to try it out, the kernel is available at http://www.csv.ica.uni-stuttgart.de/homes/ths/linux-mips/mips64-linux-ip28-2001-07-20.tar.gz Thiemo ------------------------------------------------- >> bootp(): init=/bin/sash Setting $netaddr to 10.0.0.5 (from server rembrandt) Obtaining from server rembrandt 1750384+278528+259632 entry: 0xa8000000201b4000 ARCH: SGI-IP28 PROMLIB: ARC firmware Version 64 Revision 0 Linux version 2.4.5-1 (ths@rembrandt) (gcc version 3.1 20010501 (experimental)) #78 Mon Jul 16 17:06:48 CEST 2001 Loading R10000 MMU routines.
