Hi,
I have problem with flashing W25Q256JVFQwith latest git version of flashrom.
root/Temp/flashrom/flashrom -p buspirate_spi:dev=/dev/ttyACM0 -c W25Q256.V -w Upall_VTH52X1D.20180622.bin flashrom p1.0-100-gcabe320 on Linux 4.14.0-kali3-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). Bus Pirate firmware 6.1 and older does not support SPI speeds above 2 MHz. Limiting speed to 2 MHz. It is recommended to upgrade to firmware 6.2 or newer.
