I have a Dell Inspiron 5559 Laptop which contains a Winbond 25Q128FVSQ Chip. I tried running flashrom natively on the laptop and got the usual EC warning so i stopped there. I then desoldered the SMD chip off the motherboard and hooked it up to a RPI and connected it through the SPI protocol. Flashrom then recognized it as a "Generic" flash chip and would not allow the data to be read as it was still unrecognized.
did you connect all input pins of the flash chip? A common error is to leave /HOLD and /WP floating. But they need a defined state. /HOLD has to be pulled up (towards VCC). /WP up too (might as well be down depen- ding on the chip's configuration, but up always works).
