Hi, I am trying to patch my BIOS. To do so, I am trying to flash a patched image of my BIOS. Unfortunaltely, when I flash the image, I keep having the same error :
Verifying flash... FAILED at 0x00000010! Expected=0x5a, Found=0xff, failed byte count from 0x00000000-0x00ffffff: 0xa81085 Your flash chip is in an unknown state.
WP and HOLD are linked to 3.3V (as mentionned in the W25Q128 datasheethttps://www.mouser.fr/datasheet/2/949/w25q128jv_revf_03272018_plus-1489608.pdf#%5B%7B%22num%22%3A194%2C%22gen%22%3A0%7D%2C%7B%22name%22%3A%22XYZ%22%7D%2C69%2C364%2C0%5D)
I saw this mail archivehttps://www.mail-archive.com/flashrom@flashrom.org/msg14880.html where Shane has the exact same problem. Therefore, I believe I have a write protection problem (as I always have the same error byte at the same address).
Shane solved his problem using the flashrom GUI. I know it is not maintained anymore, but I can't even find an archive. Do you know where I could find one ?
Also, I see in the datasheet that I can send specific instructions to my EEPROM. I believe flashrom sends automatically these instructions, but is there a way for me to check that my chip is not stuck in readonly for example ?
Cordialy, Quentin Kaufman
