• I am having problems with some pins of nodemcu & espruino. I tried all available pins (GPIO0 to GPIO16) and I can only 'turn on' the pins

    D0 >> GPIO0
    D1 >> TX
    D2 >> GPIO2
    D3 >> RX
    D4 >> GPIO4
    D5 >> GPIO5

    when I try to drive other pin I get the next error: "ERROR: Cannot change pins used for flash chip"
    How I can drive the pins GPIO12, GPIO13 & GPIO14 ???
