Hi all, I'm currently involved in a compiler course where we use mips assembly for pedagogical reasons. Up to recently, we were only using emulators: spim, gxemul, maybe qemu some day. That's nice, but not so fun, so I searched and found two real pieces of mips hardware: a SGI Indigo (IP20) and an Indigo2 (IP22). They're both operational (Irix+NetBSD on the IP20, NetBSD on the IP22). But since I'm rather a Debian user than a BSD one, I also tried the Debian/mips port:
- Concerning the IP20, I initially got confused by the Indigo vs. Indy naming convention and tried debian on it, of course with no luck, since (quoting http://www.linux-mips.org/wiki/IP20): "The indigo is not supported ... Steve Hill is working on taking the NetBSD port to Linux." Has somebody more infos on this project ? I would be interested in contributing (up to my modest means, e.g. testing stuff, etc). - What really puzzled me is my IP22, that obstinately refused to boot all the debian kernels I tried with it (sarge, woody, etch...), even if this machine seems to be supported according to debian docs. Each time, kernel gets downloaded via tftpboot, a message about initrd is displayed, and nothing more (see complete bootlog and some info found in the PROM at the end of the mail). -> in my suspect list is the video card, GU1-Extreme, that isn't supported by Xfree/Xorg. Could it prevent me to see anything, from the very start of the kernel booting ? I would be tempted to answer no, since I've tried today with a DIN-8 serial console cable, that works fine under NetBSD, and allows me to capture the bootlog that follows. But the linux boot stops at the same point as with regular keyboard+screen. Maybe is there some boot parameters to feed into the kernel ? -> Something wrong with the bootloader ? From my tests with NetBSD, I know that this PROM can only launch ecoff image, not elf. But all the kernel image I've tested are MIPSEB ECOFF executable (according to "file"). -> Could it be something wrong with the processor (R4000) ? To sum up, any hints/suggestion would be greatly appreciated... Pierre Letouzey ------------------------------------------------------------------------ Running power-on diagnostics...
