Hi, 

I try to flash Winbond W25Q64FV via Raspberry Pi 3.

Datasheet : http://www.alldatasheet.com/datasheet-pdf/pdf/555558/WINBOND/W25Q64FV.html

It fails the same as 2016 post, "Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI)."

The attached file is output of flashrom 1.0 with -o option.

If you have any help, please inform me.
