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.org
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~
