I want to use the IWDG watchdog with the maximum possible time delay of approx. 30 seconds. As the device cannot be switched off, It has to go into standby mode (HAL_PWR_EnterSTANDBYMode) instead. The issue here is, that the watchdog would wake it u...

In order to access the QSPI flash, I suspend the Touchgfx task from another thread.The other thread has highest priority. Today the function hang somewhere, maybe at this place: (void) osThreadSuspend( Task_TouchGFXHandle ); while ( osThreadIsSuspen...

There is a nasty behaviour if an overrun occurs with uart communications. I don't know if this happens generally or with our configuration only (STM32F479NI, RTOS with CMSIS v1,HAL_UARTEx_ReceiveToIdle_DMA). The Application hangs because endless ir...

Is it safe not do change the touchgfx screen, switch QSPI from and back to memory mapped mode, and only change the screen afterwards? Does Touchgfx access the QSPI only if the screen is switched or does it also access the QSPI if e.g. only a timer va...

If I look into the sourcecode of the underlying rtos functions it is not so straight forward to see if there could occur any endless looping, as there are operations with lists. An endless loop would occur, if the task never becomes suspended. Maybe ...

Yes it works, which is exactly the same as the function HAL_IWDG_Init already makes. Now, I just call HAL_IWDG_Init with the new Init parameters.

It is a STM32F479. It will try.

Hello @Sarra.S,maybe you have misunderstood my question. I need the IWDG with the longer timeout. However, as it is not possible to deactivate the IWDG if it was started once, I want to shorten the time just before sending the MCU into standby, becau...

The source code of the suspend function is:osStatus osThreadSuspend (osThreadId thread_id) { #if (INCLUDE_vTaskSuspend == 1) vTaskSuspend(thread_id); return osOK; #else return osErrorResource; #endif }So it delivers always the same value o...
