STM32C8T6 UART Not working

Trying to get STM32C8T6 UART to send data but nothing comes through. I configured the RCC, SYS, USART1 (baud 9600) and the integrated led on cubemx.  Tx connected to A9, Rx to A10. My code is as follows:   


UART_HandleTypeDef huart1;
uint8_t bufftx[10]="HELLO";
void SystemClock_Config(void);
int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_DMA_Init();
MX_USART1_UART_Init();
while (1)
{
HAL_GPIO_TogglePin(LED_GPIO_Port,LED_Pin);
HAL_UART_Transmit(&huart1, bufftx,10,100);
HAL_Delay(200);
}
}

As you can see there's not much to it. Im using the same code in my nucleo f103 and it works fine. Why doesnt it work on the blue pill?
