Hi Aurelian,
Thanks for the bug report. I've just downloaded your image above and tested it against a fresh build of OpenBIOS r1235 here and it works fine for me (QEMU 1.7, gcc 4.7.1, sparc-elf-gcc cross-compile on Debian amd64). Is there anything else about your build environment that may be different somehow?
I have tried on almost the same build environment than you, and I also on a native gcc 4.8 compiler on sparc. For me this also doesn't work with the OpenBIOS version provided in QEMU 1.7.0, using the following command:
qemu-system-sparc -hda /tmp/debian_etch_sparc_small.qcow2
Best regards, Aurelien
Hi Aurelien,
Ahhh I see now - there was a change a while back to the way in which boot ordering information was passed from QEMU to OpenBIOS (with respect to default devices) in order to determine default boot devices. The net result was that things didn't work without an explicit boot device specified added to the QEMU command line.
At the moment, you should be able to boot by adding "-boot c" to your QEMU command line. I'm not sure why that particular commit triggers the bug in your case though. Do you think that booting QEMU in this way without a specified boot device is a bug? If so, any insight as to what causes this would be gratefully appreciated.
ATB,
Mark.
