Nucleo F767ZI - Led LD4 RED
Hi,
I'm new to stm32 boards and I'm using it on platformIO with Arduino framework.
I have problems with the led LD4 (st-link led).
- When I use the USB cable (JP3 jumper on U5V -> powering the board using usb) the power led LD6 is green but the LD4 is red. When I upload the code the LD4 blinks red and then stable red again once flash is completed and nothing happens (in the code I turn on/off led LD1 and print something).
- When I use external power (7.6V battery on VIN, JP3 jumper on VIN) the power led LD6 is green, the LD4 is green as well. Once I upload the code the LD4 blinks red and then stable red again once flash is completed and nothing happens.
- Also, I tried doing the same thing with framework STM32cube but no luck (same behaviour).
Could you help me, what am I doing wrong?
- This is my .ini file:
#include <Arduino.h>
#define LED_PIN PB0 // Default user LED (LD1)
void setup() {
Serial.begin(115200);
pinMode(LED_PIN, OUTPUT);
Serial.println("Setup Complete");
}
void loop() {
digitalWrite(LED_PIN, HIGH); // Turn LED on
delay(500);
digitalWrite(LED_PIN, LOW); // Turn LED off
delay(500);
}
- This is the output after flashing:
