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!! 2014-03-12 19:40 GMT+08:00 Idwer Vollering <[email protected]>: > > > > 2014-03-12 11:23 GMT+01:00 yu chyuan fu <[email protected]>: > > Hi All >> >> I am a novice with coreboot.
