[CubeMX feature request]Please add an user section after the HAL_Init()

Dear STM32 Cube MX developers!

I am facing with the following problem, and I have not been able to find a proper solution:

I am using a STM32F103 with CDC stack via USB.

I have to add a code snippet to force the re-enumeration between the debug sessions.

Here is the generated code:

/* USER CODE BEGIN 1 */

uint8_t i, checksum; /* USER CODE END 1 */ /* MCU Configuration----------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* Configure the system clock */ SystemClock_Config(); /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_USART1_UART_Init(); MX_USB_DEVICE_Init(); /* USER CODE BEGIN 2 */ /* USER CODE END 2 */ /* Infinite loop */ /* USER CODE BEGIN WHILE */�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�? */

I need to add my code after the

SystemClock_Config();

but before the

MX_USB_DEVICE_Init();

I have not found any user generated sections between these two sections.

Hi

Marton.Miklos

‌,

Thanks for the suggestion! I will forward this to MX our team.

Hello

Marton.Miklos

,

Just for my information and to know where we can put the user section you want, which code do you want to put between the SystemClock_config and USB_Device_Init?

By the way, will it solve your issue if we put the user section begin and end just after the SystemClock_config (hence before the GPIO_Init)?

Hello Eric,

Thank you for your quick response!

I am developing an USB CDC based application for a STM32F103 based board, and my board did not get re-enumerated between debug sessions unless I pull the D+ line to ground for 100 ms, (The re-enumeration would be required for the host application.)

It is going to be an USB powered board, so this feature will not be in the final firmware, but I need it during the development.

Technically the best would be placing user sections to all of the MX_*_Init() functions (MX_USB_DEVICE_Init in my case).

I know the following idea would goes beyond the topic of this question, but I would recommend to extend the CubeMX code parser in such a way that users could put code everywhere between a general comment pair like this:

/* USER CODE BEGIN Custom code */ 
... 
/* USER CODE END Custom code */�?�?�?�?�?�?�?

Hello

Marton.Miklos

,

I will keep you informed as soon as we have some news about the target release where the fix will be delivered.

Hi Eric,

Do you any updates on this?

Thanks in advance!

Hello

Marton.Miklos

, We propose to add a pre, and post, user code sections into MX_USB_DEVICE_Init function. Then it will looks like: void MX_USB_DEVICE_Init(void) { /* USER CODE BEGIN USB_DEVICE_Init_PreTreatment */

/* USER CODE END USB_DEVICE_Init_PreTreatment */

/* Init Device Library,Add Supported Class and Start the library*/

USBD_Init(&hUsbDeviceFS, &FS_Desc, DEVICE_FS); USBD_RegisterClass(&hUsbDeviceFS, &USBD_AUDIO); USBD_AUDIO_RegisterInterface(&hUsbDeviceFS, &USBD_AUDIO_fops_FS); USBD_Start(&hUsbDeviceFS);

/* USER CODE BEGIN USB_DEVICE_Init_PostTreatment */

/* USER CODE END USB_DEVICE_Init_PostTreatment */

}

To be sure it will fullfill your needs, could you please share your ioc ?

This will be in CubeMX4.23 planned in Q3 2

Kind Regards Sirma

Hello

‌

Amazing news!

ThesePreTreatment and PosTreatment sections will be added to each function or just to the MX_USB_DEVICE_Init?

Here is my ioc file:

https://www.dropbox.com/s/nje8srs0gfpoqas/xlineusb.ioc?dl=0

And here is my current code:

/* init function */ void MX_USB_DEVICE_Init(void){ /* USER CODE BEGIN Workaround */ GPIO_InitTypeDef GPIO_InitStruct; /*Configure GPIO pin Output Level */ HAL_GPIO_WritePin(USB_R_P_GPIO_Port, USB_R_P_Pin, GPIO_PIN_RESET); /*Configure USB DP pin as GPIO */ __HAL_RCC_GPIOA_CLK_ENABLE(); GPIO_InitStruct.Pin = USB_R_P_Pin; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(USB_R_P_GPIO_Port, &GPIO_InitStruct); HAL_Delay(150); HAL_GPIO_WritePin(USB_R_P_GPIO_Port, USB_R_P_Pin, GPIO_PIN_SET); /* USER CODE END Workaround */ /* Init Device Library,Add Supported Class and Start the library*/ USBD_Init(&hUsbDeviceFS, &FS_Desc, DEVICE_FS); USBD_RegisterClass(&hUsbDeviceFS, &USBD_CDC); USBD_CDC_RegisterInterface(&hUsbDeviceFS, &USBD_Interface_fops_FS); USBD_Start(&hUsbDeviceFS);}�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?
