Good day, Few days ago i've bought new Winbond W25Q64BVDAIG flash, getting errors during erasing or writing. Read is good. W25Q64FV... is errased and flashed well. W25Q64BVDAIG flashing works fine in WindowsXP by CH341A - USB Programmer 1.30. In Willem LPT Programmer set to 3.3V works fine too.  CH341A  - black.     W25Q64BV... during error device stops respond with "run" led on, needs reinsert to USB to get it again. ~$ sudo flashrom --programmer ch341a_spi -r Z77EXT62.90A.bin [sudo] пароль для xxxxxx: flashrom v1.2 on Linux 5.10.0-17.1-liquorix-amd64 (x86_64) flashrom is free software, get the source code at   https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
