STM32F103RCT6

[EG-bit]

Hello, sorry for the trouble. I ran into a problem, it is not possible to correctly flash the microcontroller, that is, I configure the outputs and set it to a low state and the PD1 output is always set to the high level. When I set other outputs to the upper level, then nothing changes. When flashing through CubeIDE, everything is correctly stitched. Help please, I'm not good at programming, I'm just learning.

My test code:

#define R1    PA8
#define R2    PC8
#define R3    PC7
#define R4    PC6
#define R5    PB15
#define R6    PB14
#define R7    PB13
#define R8    PB12
#define R9    PD1
#define R10   PD0
#define R11   PC13
#define R12   PB9
#define R13   PB8
#define R14   PB4
#define R15   PB3
#define R16   PA15

const bool Relays[] = {R1,R2,R3,R4,R5,R6,R7,R8,R9,R10,R11,R12,R13,R14,R15,R16};

void setup() {

  for(int a = 0; a < 16; a++){
   pinMode(Relays[a], OUTPUT);
   digitalWrite(Relays[a], 0); 
  }
digitalWrite(R1, HIGH);  //Relay test
}

void loop() {
  // put your main code here, to run repeatedly:

}

Before flash you should be able to compile...

const uint32_t Relays[] = {R1, R2, R3};

void setup() {

  for (int a = 0; a < 3; a++) {
    pinMode(Relays[a], OUTPUT);
    digitalWrite(Relays[a], 0);

If it compile, maybe you not used this core.
