I tried using LAB, but the LAB kernel build failed with what looked like linker errors: kernel/built-in.o: In function `getnstimeofday': (.text+0x15491): undefined reference to `__umoddi3' kernel/built-in.o: In function `do_gettimeofday': (.text+0x1553c): undefined reference to `__udivdi3' kernel/built-in.o: In function `do_gettimeofday': (.text+0x1555f): undefined reference to `__umoddi3' kernel/built-in.o: In function `update_wall_time': (.text+0x15c55): undefined reference to `__udivdi3' kernel/built-in.o: In function `update_wall_time': (.text+0x15c7f): undefined reference to `__umoddi3' make[1]: *** [vmlinux] Error 1 I highly doubt that the vanilla kernel from kernel.org had build issues, so I'm guessing one or more of the patches are suspect.

I thought the buildrom config/build process was going to take care of that, but I guess I was mistaken. If I understand correctly, leaving out the ~36k chunk will still allow me to have all the core functionality, just without VGA output.. Of course, when this is all done and working (crossing my fingers) I won't be able to resist adding that Tetris-like video game to the ROM. > > Serial console output seems to indicate that basic coreboot > > initialization was happening, but maybe never got to the > point where > > it could give me useful VGA output. > > Including the boot log once you decide which payload you want > to use would help us track it down. > I will definitely do that, as soon as I can get a successful build again. :) It built successfully before, since I chose FILO as my payload, but now with LAB, I haven't yet created a ROM image. Thanks again for your patience and help. -Bijoy -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
