I added the following line to devices.txt:
Name="W25Q128FVSIG",ID="EF4018",Class="W25X10",Category="SERIAL_EPROM",MFG="Winbond",Vcc="3.6V",CodeSize="16777216",Adapter="ADP-081, ADP-027 adapter";
I can properly ID the chip, but reading end in a frozen window without any read progress. Does 3X not support w25Q128? If so, does 4X support the chip?
