Arduino for STM32

'Couldn't find the DFU device: [1EAF:0003]'.
All I am getting is this when I try to program stm32 using arduino ide.Any way to solve this?

COM port is not visible because there is no COM port until you upload program that has COM port enabled.
Those bootloaders (maple bootloader and HID bootloader) do not use COM port for upload. They detect board by specific ID. COM port is needed only to reset board from Arduino IDE and enter ...

you need to install a sketch as like

void setup() {
Serial.begin();
while(!Serial); // optional, wait for host to connect
pinMode(LED_BUILTIN, OUTPUT);
}

#define CR '\r'
#define LF '\n'

void loop() {
Serial.println("hello world");
if(Serial.available()) {
int16_t c = Serial.read ...
