Thanks David.
I tried flashrom1.2 , W25Q128FW and W25Q256.W are not in the support list.
I want use Raspberry only to flash W25Q128FW and W25Q256.W.

Hi Yulia,
Can you add W25Q128FW and W25Q256.W to flashrom support list to use Raspberry only? Thanks for your responding.

Hi Amin,

Sorry for the late reply, do you still need any other support?
Thanks.

Yulia

Hi Amin,
Please note that the W25Q128FW is a 1.8V chip, while Raspberry PI IOs are 3.3V.

For Dediprog, pass in the `voltage` parameter, e.g. `flashrom -p dediprog:voltage=1.8 -r foo.bin`

Also, as Mike mentioned it will help if we know the version of flashrom which you are trying to use. Some distributions provide very old versions.

Hi David Hendricks,
“No EEPROM/flash device found” pop after I added below code to flashchips.c and flashchips.h to install flashrom in Raspberry 4B.
pi@raspberrypi:~ $ sudo flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=4096
flashrom  on Linux 4.19.57-v7l+ (armv7l)
flashrom is free software, get the source code at https://flashrom.orghttps://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fflashrom.org%2F&data=02%7C01%7CAmin.Wu%40amd.com%7C0918f84b12cd4e6ccaa908d7f22d7c7c%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637244149513350601&sdata=zPYtudefIHhxJ%2BC6cDnySYIVwQC30n4QvnuPa0xZbco%3D&reserved=0

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

Do you have any suggestions? Thanks 😊

Hi Winbond,
Do you have a plan to support flash bios for W25Q128FW and W25Q256.W via flashrom in Raspberry?

Hi David, Hendricks,
Can you share the flashrom link to download which support W25Q128FW and W25Q256.W?
Now I used DediProg to flash these bioschip. I can try with raspberry to flash when I get the flashrom from you. 😊
It is great help for me if flashrom support W25Q128FW and W25Q256.W. I tried edit flashchip.c and flashchip.h, but flash fail and fail. ☹
Thank you flashrom developer. Good job! Flashrom~Yes~
