Fail on CHIP "W25Q256.V"

[Igor Omelchenko]

Hello!

Tried to flash BIOS on "W25Q256.V" chip, got below  errors:
 (Tried with 24-45k spispeed. tried with -n and without -n)
Thanks for your amazing work!

squid@squid:~$ sudo flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=24000
-n -w  /squid/Squid/Files/SES5_000000_2020WW45.1.01.bin
flashrom  on Linux 4.14.108-ti-r137 (armv7l)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found Winbond flash chip "W25Q256.V" (32768 kB, SPI) on linux_spi.

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 check the possible failure reasons that aren't a fault of flashrom:
1) old flashrom version. Compile the latest version from the source code
2) unreliable connection or too long cables between a flasher and a chip
