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

[Khouloud ZEMMELI]

@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.

[Khouloud ZEMMELI]

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

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

[MQi.1]

I met the same error:

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(&hlpuart1) != HAL_OK)
 {
 Error_Handler();
 }
 /* USER CODE BEGIN LPUART1_Init 2 */
 
 /* USER CODE END LPUART1_Init 2 */
 
}

what maybe the reason?

[Khouloud ZEMMELI]

Hi @MQi.1​ 

Can you please explain what's your problem ?

Thanks, Khouloud

[MQi.1]

And, under it was another "error: invalid storage class for function"

static void MX_GPIO_Init(void)
{
 GPIO_InitTypeDef GPIO_InitStruct = {0};
 
 /* GPIO Ports Clock Enable */
 __HAL_RCC_GPIOG_CLK_ENABLE();
 HAL_PWREx_EnableVddIO2();
 __HAL_RCC_GPIOB_CLK_ENABLE();
 
 
 /*Configure GPIO pin Output Level */
 HAL_GPIO_WritePin(LED_BLUE_GPIO_Port, LED_BLUE_Pin, GPIO_PIN_RESET);
 
 /*Configure GPIO pin : LED_BLUE_Pin */
 GPIO_InitStruct.Pin = LED_BLUE_Pin;
 GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
 GPIO_InitStruct.Pull = GPIO_NOPULL;
 GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
 HAL_GPIO_Init(LED_BLUE_GPIO_Port, &GPIO_InitStruct);
 
}
