Hi,I wonder if you can help us? In one of our projects we are using the STM32F205ZGT6 Microcontroller and specifically we are using the CAN bus. The problem is that when we increase the ambient temperature around the MCU to approximately 38°C to 40°C...

To give you an update to the LSE crystal oscillator startup issue with the STM32H743XIH6, we have made some more investigations and this is what we have found.There was a problem with the software, that we found. If we made a Backup Domain reset befo...

Hi Javier,Thank you for your quick reply. Our software guys were for some reason using the HSI clock and not the HSE clock as you suggested, When they switched to the external HSE clock, the temperature issue was not a problem anymore.Thanks again,Ma...

Hi Jan,Thank you for your quick response. We made a test with just resetting the backup domain and enabling the LSE with nothing else and we still see the oscillation dip. After further software timing investigations, the oscillation dip occurs in t...

Are there any errors associated with the CAN Controller on the STM32F205ZGT6 MCU which could explain the CAN bus packet failures when the ambient temperature is increased to 40°C?
