Re: [ps2hacking-devel] Some answers on digest #38 and #39

Hi there,


I'm one of the ps2hacking project admins but not the owner/admin of
this list. I've been working on porting linux-2.4 kernel to PS2, and
been interested in getting Debian working on PS2 linux kit.


|Who is running this show ?
|see http://sourceforge.net/projects/ps2hacking/
|you can look up the project admins there. they seem to be mostly japanese 
|guys, but hey, maybe they could tell themself or you could ask them.
|That brings up a rather fundamental question : Is this only for linux-kit 
|owners or for the "home brew linux" too ? if this is sony-only, please 
|tell, because then the rest of this post is totally offtopic and we should 
|start a non-sony project and/or mailing list, though i would really 
|appreciate if "sony users" and "home brewers" could work together here as 
|far as this is possible. That would surely be more to the advance of the 
|homebrewers, but after all we (euro and usa) can not buy a linux kit - 
|which i will certainly do if it is ever released here.


This list is open to everyone who are interested in hacking PS2. 
It is not only for PS2linux-kit owners and linux hackers.
I don't like reverse engineering though, I hope we can work toghther
in other area.




|Built a MIPS kernel from the CVS sources at oss.sgi.com :
|I built a 2.4 kernel from SGI's CVS using their cross-toolchain. 
|I put it on a CD (BASF/EMTEC CeramGuard) together with a system.cnf 
|that i took from a game (GTA3 i think).It seems to boot up, at least the 
|ps2 doesn't complain about "please insert ps2 disc" and the screen 


The CVS tree at oss.sgi.com won't work since the processor of the PS2
is somehow different from typical MIPS variants.

AFAIK, the only working linux-2.4 kernel is our cvs tree at
http://sourceforge.net/projects/ps2hacking, but it will not boot up
without the kit since it depends on proprietary stuff (DVD that
contains bootloader and 'SBIOS') from Sony.

There is another CVS tree at http://sf.net/projects/linux-mips. 
their PS2 port seems imcomplete at present.


'normal' toolchains for MIPS variants also does not work because of
the nasty bugs of the processor. I can post source code of GPL'ed
stuff such as GNU toolchains, glibc, and most part of the linux-2.2
kernel comes with the kit. please let me know if you need them.


|non-sony kernel sources, i think i will try that. Could someone with a 
|linux kit post some hw info on the ps2, as far as your license allows 
|that?

The kit comes with some hw documents though, no one can legally offer
a copy of the document because of its license terms :-(
