Hello, I want to start ethernet on stm32f7 but task always sticks on one place -
if (inHandlerMode())
{
if (xSemaphoreTakeFromISR(semaphore_id, &taskWoken) != pdTRUE) {
return osErrorOS;
}
portEND_SWITCHING_ISR(taskWoken);
}
else if (xSemaphoreTake(semaphore_id, ticks) != pdTRUE) {
return osErrorOS;
}

, and when I put breakpoint I receive this message:
Program received signal SIGINT, Interrupt.
0x08005352 in vPortRaiseBASEPRI () at C:/Projects/STM32F7/Middlewares/FreeRTOS/Source/Portable/GCC/ARM_CM7/r0p1/portmacro.h:215
215 __asm volatile

Any idea why is that. When I put my code in exmple of ethernet at stm it works fine.

I’m not sure where this code comes from.

	if (inHandlerMode())
	{
		if (xSemaphoreTakeFromISR(semaphore_id, &taskWoken) != pdTRUE)
		{
			return osErrorOS;
		}
		portEND_SWITCHING_ISR(taskWoken);
	}
	else if (xSemaphoreTake(semaphore_id, ticks) != pdTRUE)
	{
		return osErrorOS;
	}

It looks like inHandlerMode() returns true if the function is called from an ISR?

Where did you get your NetworkInterface.c from? Does that contain the above code?

NetworkInterface.c I didnt have this file.

int32_t osSemaphoreWait (osSemaphoreId semaphore_id, uint32_t millisec)
{
  TickType_t ticks;
  portBASE_TYPE taskWoken = pdFALSE;  
  
  
  if (semaphore_id == NULL) {
    return osErrorParameter;
  }
  
  ticks = 0;
  if (millisec == osWaitForever) {
    ticks = portMAX_DELAY;
  }
  else if (millisec != 0) {
    ticks = millisec / portTICK_PERIOD_MS;
    if (ticks == 0) {
      ticks = 1;
    }
  }
  
  if (inHandlerMode()) {
    if (xSemaphoreTakeFromISR(semaphore_id, &taskWoken) != pdTRUE) {
      return osErrorOS;
    }
	portEND_SWITCHING_ISR(taskWoken);
  }  
  else if (xSemaphoreTake(semaphore_id, ticks) != pdTRUE) {
    return osErrorOS;
  }
  
  return osOK;
}

This is whole function. It is in cmsis_os.c

There is a pre-configured STM32 Ethernet example here:

This is not a file that is provided in the official FreeRTOS
distribution. I think it is the CMSIS wrapper provided by ST.

Thank you, I’ll asked ST for more information
