Posted on May 28, 2015 at 12:52Hi friends,
I create a sample project with:
- STM32Cube FW_F1 V1.0.0
- F103
- USB CDC
Shortly I found this lines in usbd_conf.c
[code]
/**
* @brief static single allocation.
* @param size: size of allocated memory
* @retval None
*/
void *USBD_static_malloc(uint32_t size)
{
static uint8_t mem[sizeof(USBD_CDC_HandleTypeDef)];
return mem;
}
/**
* @brief Dummy memory free
* @param *p pointer to allocated memory address
* @retval None
*/
void USBD_static_free(void *p)
{
free(p);
}
[/code]
As you can see, we don't have a real malloc, but we try to free a NON MALLOC pointer.
I think this is a BUG!
