Hi All,
I have an Intel/Truxton (Tolapai/EP80579) type platform that I am using coreboot and seabios on. Up to now I have been using a pre-compiled binary from Kevin's download site:
http://linuxtogo.org/~kevin/SeaBIOS/seabios-0.5.1.tar.gz
and that has been working fine. (The coreboot is modified to support some changes on this particular hardware platform).
Now the problem is that I want to generate seabios binaries from source. And I can't seem to be able to compile a working one.
My host build system is a Ubuntu 9.10 x86_64 install (using the most up to date packages). This a gcc-4.4.1 and binutils-2.20 setup.
If I get the source seabios-0.5.1 package from Kevin's download page and compile that I end up with a bios.bin.elf that is:
-rwxr-xr-x 1 gerg gerg 1048716 2010-02-17 15:11 bios.bin.elf
Hmm, rather large :-) The actual contents maybe ok:
out/bios.bin.elf: file format elf32-i386
Sections: Idx Name Size VMA LMA File off Algn 0 .text 00013000 000ed000 000ed000 000ed000 2**4 CONTENTS, ALLOC, LOAD, READONLY, CODE
The file offset is looking bad here.
If I instead use a binutils-2.18 "ld" that I have lying around (doing "make LD=i386-linux-ld") then I end up with a more reasonable sized bios.bin.elf of 82060 bytes. But this bios.bin.elf just hangs after being loaded by coreboot on my target.
I tried compiling this same seabios version (0.5.1) on an older Fedora Core 9 system (also an x86_64 install), and again that produced a non-working bios.bin.elf.
I also got the latest seabios git tree and tried that. I also couldn't get a working seabios binary using that either.
What versions of gcc/binutils do others use? Does anyone have any ideas where by building could be going wrong?
Regards Greg
