Hello Anton, In the past I have seen such logging code added to a BIOS code base. It was for Phoenix legacy if I remember correctly. A challenge with this method is using it to exactly pinpoint a problem. For this board I have the luxury of a jtag debugging setup, the Sage SmartProbe. This arrangement is very handy for boot time reduction. I do a crude form of profiling by breaking in randomly during post. I still find it spending some time in lzma decode of ramstage. That time was reduced by the -flto compiler option. Thanks, Scott -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
