Pin 30 not working on Teensy 3.2

[roko]

So, I bought Teensy 3.2 and everything works fine except for pin 30. Digital write does nothing and analog read gives me values like anything isn't connected. Why is this a problem? Any help would be appreciated.

I can't say why it's not working for you, but I can confirm it does indeed work if you run this code and connect a LED+resistor.

void setup() {
  pinMode(30, OUTPUT);
}

void loop() {
  digitalWrite(30, HIGH);
  delay(1000);
  digitalWrite(30, LOW);
  delay(100);
}

The LED definitely does blink. Here's a photo.

I've tried and it's simply dead all surrounding pin do indeed seem to work.

I suspect it's possible to kill a single pin with the rest of the chip still OK, by destroying that pin's output buffer, for example by a large enough ESD hit.

EDIT: You can also get the same effect with one bad solder joint on the chip's pin, which you could confirm if you have steady hands and a fine enough probe.

I guess you are right but it could be also bad solder joint at that pin on chip.
