Bug in generated code for MX_LPUART1_UART_Init

[STawn.1]

In a project for a STM32L4S7ZITx with LPUART1 enabled the following code is generated:

/**
  * @brief LPUART1 Initialization Function
  * @param None
  * @retval None
  */
static void MX_LPUART1_UART_Init(void)
{
 
  /* USER CODE BEGIN LPUART1_Init 0 */
 
  /* USER CODE END LPUART1_Init 0 */
 
  /* USER CODE BEGIN LPUART1_Init 1 */
 
  /* USER CODE END LPUART1_Init 1 */
  hlpuart1.Instance = LPUART1;
  hlpuart1.Init.BaudRate = 115200;
  hlpuart1.Init.WordLength = UART_WORDLENGTH_8B;
  hlpuart1.Init.StopBits = UART_STOPBITS_1;
  hlpuart1.Init.Parity = UART_PARITY_NONE;
  hlpuart1.Init.Mode = UART_MODE_TX_RX;
  hlpuart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;
  hlpuart1.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE;
  hlpuart1.Init.ClockPrescaler = UART_PRESCALER_DIV1;
  hlpuart1.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT;
  hlpuart1.FifoMode = UART_FIFOMODE_DISABLE;
  if (HAL_UART_Init(&hlpuart1) != HAL_OK)
  {
    Error_Handler();
  }
  if (HAL_UARTEx_SetTxFifoThreshold(&hlpuart1, UART_TXFIFO_THRESHOLD_1_8) != HAL_OK)
  {
    Error_Handler();
  }
  if (HAL_UARTEx_SetRxFifoThreshold(&hlpuart1, UART_RXFIFO_THRESHOLD_1_8) != HAL_OK)
  {
    Error_Handler();
  }
  if (HAL_UARTEx_DisableFifoMode(&huart1) != HAL_OK)
  {
    Error_Handler();
  }
  /* USER CODE BEGIN LPUART1_Init 2 */
 
  /* USER CODE END LPUART1_Init 2 */
 
}

Line 39 is the only place that huart1 is referenced in any of the generated code. I assume this is meant to be hlpuart1.

Hello @STawn.1​ 

It will be internally checked

@STawn.1​  Issue confirmed and it will be fixed,

Thanks for your feedback.

Chiming in that this issue also just affected me today, so it is still not fixed.

Hello @CBald​ 

The fix will be available for the next CubeMX release (6.1.0).

I'd like to add to this bug: it also happens in the LPUART1_IRQHandler:

void LPUART1_IRQHandler(void)
{
  /* USER CODE BEGIN LPUART1_IRQn 0 */
 
  /* USER CODE END LPUART1_IRQn 0 */
  HAL_UART_IRQHandler(&huart1);            //<--- Here, huart1 should be hlpuart1
  /* USER CODE BEGIN LPUART1_IRQn 1 */
 
  /* USER CODE END LPUART1_IRQn 1 */
}

Hi @Mhd​ 

Could you please share your ioc file ?

Thanks

Khouloud

[CBald]

Mine exhibits the same behavior, huart instead of hlpuart in the IRQHandler

See attached file

@Mhd​  & @CBald​  fix is done, it will be available in the next release.

Thanks for your feedbacks
