Hello, hope you can help me, I have bricked my chromebox, been using a pomona clip via a raspberry pi on my spi, running flashrom, which finds my winbond chip but when i try to write to it, flashrom comes back with an error saying "image size (4096 B) doesn't match the flash chip's size (8388608 B)!"
That would mean that you try to write a 4 kB file to an 8 MB flash chip. flashrom won't allow that for good reasons. It seems like you are confusing two files IMHO. The 4 kB file is probably just the flash descriptor but that alone is probably not what you want to write.
and when i go to the properties of the image it is similar to the chip's size.
I certainly doubt that. It is more likely that you are comparing something else than flashrom does (i.e. you are looking at the wrong file).
Have tried using hex editor on windows and flashing that format but keep getting same error message, hope you can help me with regard to this, thankyou.
You probably want to use a pre-built image by John Lewis. They should have the correct size...
Have managed to flash John Lewis's latest rom to my stumpy chromebox, it has revived it and then I installed windows 10 64bit version used it flawlessly for a day, went to shut down and blue power on button just kept flashing so I decided to hold it until it went off, the next day I pressed the power button and now nothing happens, back to were I was before I flashed. (the fan spins for a second and stops for 2 or 3 seconds and repeats this process). Have tested the power supply with a multimeter for voltages and all seems to be good. Do you think my bios chip has failed or could it be more hardware related.

Hi,
it could be a completely unrelated hardware fault as well. I am not familiar with the chromebox and it certainly flashrom has no direct influence on the behavior of the device currently so I suggest you ask John or on the coreboot mailing list instead.
