Hello folks,Anyone knows the default CAN clock frequency on STM32H753 MCU when powered on, assuming the CAN bit timing register (CAN_BTR) was not set by FW during the initialization?If this value would be a random, could it be changed depending on re...

Hi all,Can anyone confirm if these two type of STM32 MCU, STM32H753BIT6 and STM32H753VIH6 use the same die although they have different packages? Best fourhes

Thanks TDK. Yes, it's a bug but want to see any risk associated with it.

Thanks AScha.3. Does this mean not setting up the value would never work?

Thanks. Without setting this register, CAN communication was working mostly and sometimes it didn't work. I wonder where this difference is coming from. If the default value is 0A33 which makes 500kbps, it makes sense as I see it. However, sometimes ...

It could be. A good point. Will check it with our CM.Thanks.Best.
