Hi everyone, I'm developing a bootloader that works like this. I was inspired by the example: https://github.com/pramodk51/bootloader_for_stm32f4. I developed this initially on Nucleo F439ZI for the test phase and I managed to implement it with the ...
The manual I have for the STM32U585 describes the Independent Watchdog (IWDG) peripheral and says it has an Early Wake-Up Interrupt (EWI) feature. The manual says "Wake-up from Stop with interrupt is supported only in Stop 0, Stop 1, and Stop 2 mode...
Hi all,I'm using STM32F429BIT6。my question is: C3 is 3.3uF±10%，How do you like this circuit?When WDG reset in the MCU STM32F429BIT6,It will lead to CMOS failure of the MCU NRST？If C3 is 2.2uF±10%，the CMOS of the MCU NRST will be OK？Thanks！NRST Circu...
Erratum 2.2.1 (Unstable LSI when it clocks RTC or CSS on LSE) indicates the following workaround:If LSI clocks the RTC or when the LSECSSON bit is set, reset the backup domain upon each VDD power up(when the BORRSTF flag is set). If VBAT is separate ...
Posted on February 13, 2018 at 13:16The current data sheet for the STM32F303CC (DocID023353 Rev13) shows on page 80 the characteristics of the LSI oscillator.Its frequency starts from min. 30kHz to typical 40 and max. 50 kHz (all at 3.3V in the max....
Hi,I stumbled across a problem with the LSI when i realized, that my IWDG was about 20% faster than it should be.The clock is behaving very irregularly, this is more than the deviation in the datasheet. I read out the LSI from PA2 with an oscilloscop...
Hi,I am facing an issue with IWDG in STM32G051G6U6.HAL_IWDG_Refresh(&hiwdg); not refreshing IWDG and the core resets after IWDG overflow time.IWDG overflow is set at 13Sec (varying wrt prescaler) and I am refreshing it at every 1 sec.Counter presc...
Hello all!I am reaching out to see if anyone here has any experience jumping from application code to the embedded system bootloader while using the System Window Watchdog (WWDG) peripheral. I am using the STM32G431 series. The ST documentation (AN26...
Hi, (STM32G0C1RET6 for this part number ARM® Cortex®-M0+ STM32G0 Microcontroller IC 32-Bit Single-Core 64MHz 512KB (512K x FLASH 64-LQFP (10x10))two type of pin descriptions have mentioned in the datasheet, I confused which one I have to t...
Hi,I have been banging my head for a while now and decided to reach out for help. I am trying to get the IWDG to freeze during Standby. Based off the reference manual I have toggled the IWDG_FZ_SDBY bit to 0. In STM32CubeProgrammer it is set to 0 so ...
