hello,


I had a bad bios flash, so i wanted to flash original bios using flashrom but it failed.

I was using Raspberry Pi 3, bios chip is winbond W25Q64FW

flashrom v0.9.9-r1954 on Linux 4.4.13-v7+ (armv7l)
flashrom is free software, get the source code at https://flashrom.org

Calibrating delay loop... OK.
Found Winbond flash chip "W25Q64.W" (8192 kB, SPI) on linux_spi.
Reading old flash chip contents... done.

Uh oh. Erase/write failed. Checking if anything has changed.

Apparently at least some data has changed.
Your flash chip is in an unknown state.
Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom at flashrom.org, thanks!
pi at raspberrypi:~ $


Thank you for any information.
