Hello everyone,
This is my first time ever using a teensy so this might be a dumb post but here it goes.
I cant seem to get my teensy 4.0 to work with external power to the Vin, without usb.
Ive followed this example:
https://www.pjrc.com/teensy/external_power.html
Ive cut the 5vin from the usb on the board.
The source is 5v (which ive tested with a multiemter) and connected the 5v to the 5v in of the teensy and the ground of the teensy to the ground of the source. And well, nothing, I cant get the Teensy to boot.
Ive tested with Leds to see if it was an issue with the power source but it works as expected.
The only bit of code running is the blink tutorial:
Any help would be greatly appreciated.

Code:
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop() {
digitalWrite(ledPin, HIGH); // set the LED on
delay(1000); // wait for a second
digitalWrite(ledPin, LOW); // set the LED off
delay(1000); // wait for a second
}
Any help would be greatly appreciated.
