Re: [coreboot] [Coreboot] About (re)flash BIOS utility

Hi Idwer & peter

Yes,i already have compile crossgcc utility before 'make menuconfig'.
Like Idwer said , The output debug code "0x02" not found from coreboot
source code.
So i don't have debug direction .
My mainboard is company customization by sandybridge platform and flash
chip is Winbond W25Q64V 8M
Hardware spec please see attached file.

So should i need to try use flashrom utility or still use vendors provide
flash utility ??

Thanks for your reply and help!!
