genericSTM32F405RG serial not working

[JyeSmith]

Hi,

Im having an problems with serial on the F405. Below is the ini and script. The bluepill works as expected, and changing to the F405 results in the led blinking but no serial.

Serial upload works as expected with uart1 (PA9 and PA10) on both targets

Is there something Im missing? or an actual issue?

Cheers

platform = ststm32@14.0.1
framework = arduino
; board = genericSTM32F103C8
board = genericSTM32F405RG
upload_protocol = serial
monitor_speed = 9600

#include <Arduino.h>

// #define LEDPIN PC13 // genericSTM32F103C8
#define LEDPIN PA8 // genericSTM32F405RG

void setup() {
  Serial.setTx(PA9);
  Serial.setRx(PA10);
  Serial.begin(9600); 
  pinMode(LEDPIN, OUTPUT);
}

void loop() {
  Serial.println("Hello World!");  
  digitalWrite(LEDPIN, HIGH);
  delay(250);
  digitalWrite(LEDPIN, LOW);
  delay(250);
}

I got the below working 👍

.ini

    platform = ststm32@14.0.1
    framework = arduino
    board = genericSTM32F405RG
    upload_protocol = serial

    build_flags = 
       -DSERIAL_UART_INSTANCE=1
       -DPIN_SERIAL_RX=PA10
       -DPIN_SERIAL_TX=PA9
