Hello Alfin,

thanks for your report. Have you connected all input pins of the flash
chip to the programmer? The behavior shown in the log extract could be
coming from a floating write protection pin. That's pin #9 (diagonally
opposite to the pin #1 marker on the 16-pin sop/soic package). I'd
check if that pin is pulled-high towards VCC (pin #2). Likewise all
other *input* pins should be driven - either statically to GND or
VCC (ideally by resistors), or dynamically by the programmer's clock
and data out pins. HTH
