CubeMx problems with USER CODE SECTIONs

HI

I am using Cube32MX for the implementation of a USB Host + Fatfs to work with a pendrive connected to a stm32f407, generate code for SW4STM32 but in the usb_host.c file generated by Cube32MX the following appears.

#include 'usb_host.h'

#include 'usbh_core.h'

#include 'usbh_msc.h'

/* USB Host Core handle declaration */

USBH_HandleTypeDef hUsbHostFS;

ApplicationTypeDef Appli_state = APPLICATION_IDLE;

/**

* -- Insert your variables declaration here --

*/

/* USER CODE BEGIN 0 */

/* USER CODE END 0 */

/*

* user callbak declaration

*/

static void USBH_UserProcess (USBH_HandleTypeDef *phost, uint8_t id);

/**

* -- Insert your external function declaration here --

*/

/* USER CODE BEGIN 1 */

/* USER CODE END 1 */

/* init function */

void MX_USB_HOST_Init(void)

{

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

USBH_Init(&hUsbHostFS, USBH_UserProcess, HOST_FS);

USBH_RegisterClass(&hUsbHostFS, USBH_MSC_CLASS);

USBH_Start(&hUsbHostFS);

}

/*

* Background task

*/

void MX_USB_HOST_Process(void)

{

/* USB Host Background task */

USBH_Process(&hUsbHostFS);

}

/*

* user callbak definition

*/

static void USBH_UserProcess (USBH_HandleTypeDef *phost, uint8_t id)

{

/* USER CODE BEGIN 1 */

/* USER CODE END 1 */

}

As you can see in the USBH_UserProcess function, the user section number is repeated as well as at the beginning of the code in the dedicated section for the prototype of an external function.

I write a prototype and re-generate the code with Cube32MX prototype is copied inside the USBH_UserProcess function.

Now if I write code inside the user zone in the function USBH_UserProcess when regenerating code with Cube32Mx this erases the written code.

I think the fault is because the user zone number is repeated to one, I think it should be two but that is automatically generated by the Cube32Mx and I can not change it and I lose the code that I write inside that function when I have to

re-generating coded from Cube32Mx.

What would be the solution to the problem?

The Cube32Mx version is 4.19.0 STM32Cube v1.0

Thank you.

Hello,

You are absolutely right.

This has been corrected, and will be available in version 4.20 (very soon).

Thanks to have reported it.

Kind regards

Sirma
