During the process of configuring option bytes, we unfortunately got few MCUs bricked (unresponsive). In these devices, i was getting the following errors when trying to flash using STM32 programmer. (Tried both GUI and CLI with various reset modes a...
Dear STM32 users and developers, This new thread is back and is dedicated for our technical developers community to share last STM32 updates, the first part will be products documentation news such as datasheets, Erratas, Applications notes followed...
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...
Hello, I'm having an issue to use the Microcontroller debug unit (DBGMCU) on STM32H753. I have got IWDG set up and working as expected and would like to have the IWDG frozen during debugging. I have set the DBG_IIWDG1 (bit 18) of register DBGMCU_APB4...
In my application I have configured IWDG to start running.I would like to prevent the IWDG from resetting the MCU while in stop 1 mode for extended period of time.In the reference manual it says: "Once running, the IWDG cannot be stopped." But in the...
I am currently working on a project that involves integrating USB functionality for data transfer and data logging on an STM32F407VG micro-controller. Specifically, I want to log data files on an SD card and enable the user to download these logged f...
i try to crash my code to check the watchdog timer is reseting the code or not. for crashing my code i use timer interrupt. i.e TIM2_IRQHandler(){ ---------------; ---------------;}TIM_IRQHandler() instead of TIM2_IRQHandler . so, code will be ...
If you set the IWDG to start using the option byte, the watchdog cannot be disabled subsequently. Am I right thata) the prescaler can be modifiedb) the counter itself can be reloadedItem b) would be a vulnerability, surely, because faulty code could ...
Hello, I am using STM32F446RE in my project and as per the project requirements I need to have power on built in test, initiated built in test and continuous built in test on STM32F446RE. Please let me know how different built-in self-tests can be ...
Hi, I have several programm where I use either the HAL_FLASH_Program command or some EEPROM command like EE_ReadVariable16bits (directly issued from the std "eeprom_emul.h" library).To make those command functionnal i had to stop the watchdog which t...
