Question
RTC synchronization on CAN through FDCAN peripheral
I've seen improvement in FDCAN peripheral timestamping for Rx/Tx messages. However, I still find it hard to synchronize RTC peripheral among different devices with CAN, since FDCAN timestamps can't store the RTC. The closest thing it can only store is TIM3, which cannot be clocked from LSE (typical 32 kHz for RTC). Any smart idea ? Thank you !
