problems running hello in fiasco
by Fabian Sturm 26 Mar '03

26 Mar '03

Hello! I have a problem running the hello world example on fiasco. I downloaded the latest CVS version from 25.4 of fiasco and compiled it like it is described on the web. Except that the sigma0/rmgr binaries were in l4/bin/x86_586/l4v2 and not directly in l4/bin as described. I then created the following grub entry: title Fiasco, hello world root (hd0,4) kernel=/fiasco/rmgr -sigma0 module=/fiasco/main -nokdb module=/fiasco/sigma0 module=/fiasco/hello When I then boot into it I see some … [View More]

If you have overlapping modules you have no chance whatsoever. So you better fix that ;) I'm not too familiar with the FIASCO kernel boot process, but usually the problem is GRUB, not the kernel. GRUB loads the modules after all loaded elf sections of the initial kernel (which is RMGR in your case). RMGR then tries to load the modules as ELF files and figures out that some elf sections collide with the module locations and barks. This was the reason to add the modaddr feature to GRUB allowing … [View More]to relocate the load address in main mem. Simply try sticking a modaddr=0x<whatevermemoryyouhave-16MB> after the kernel=rmgr line. Note, that this is only available in the Dresden version of GRUB, not the GNU GRUB (at least AFAIK). So bake yourself a boot floppy from http://os.inf.tu-dresden.de/~fm3/grub.html. The Linux error message is due to the kernel-debugger console in L4Linux. At the end Linux tries to open the console but since it does not support all required features Lx simply falls back to VGA. So this error can be ignored even if it sounds scary. - Volkmar PS: Please post in English -- most subscribers of this list don't understand a word of German (except maybe "Bier" ;) > -----Original Message----- > From: Rudolf Weber [mailto:rfweber@tesionmail.de] > Sent: Saturday, March 15, 2003 8:21 PM > To: l4-hackers(a)os.inf.tu-dresden.de > Subject: Problem beim starten von l4linux auf fiasco > > > Hallo, > > Vorbemerkung: > Das starten von glinux bringt einen Fehler überlappender Module, > Der Fiasco beginnt da, wo glinux liegt, > folgende Änderung habe ich gemacht: > --- ./l4/kernel/fiasco/src/Makerules.BOOT.vorrudi 2003-02-25 > 11:34:43.000000000 +0100 > +++ ./l4/kernel/fiasco/src/Makerules.BOOT 2003-03-15 > 16:13:58.000000000 +0100 > @@ -7,7 +7,7 @@ > $(BOOT): kernel.o $(OBJ_BOOT) $(LIBKERN) $(MINILIBC) > @echo " ...

RE: enabling/disabling trampoline
by Volkmar Uhlig 15 Mar '03

This sounds like a problem with RMGR. Try either running L4Linux not using the "flat clan structure" (make xconfig) or enable the "Jochen compatibility/bug mode" for Hazelnut. Have you tried running the binaries of the provided RC2 tarball? They also contain a working L4Linux binary. - Volkmar > -----Original Message----- > From: Cristiano Ligieri Pereira [mailto:cpereira@ics.uci.edu] > Sent: Thursday, March 13, 2003 9:01 PM > To: Espen Skoglund > Cc: l4-hackers > Subject: … [View More]
