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 ???
