Using an STM32H750B discovery board, I'm trying to set up FDCAN. However when I activate either FDCAN1 or 2, the clock configuration needs to be adjusted, as by default, the FDCAN receives 200MHz, but van only accept up to 100. If I run the automatic resolver, it changes several values, sets the FDCAN frequency to 50MHz and the maximum frequency to 50MHz as well. The FDCAN seems to work after that, but all of my screen is garbled up, only colorful stripes are showing.
If I manually set the FDCAN Clock mux to the HSE, then everything works, but the FDCAN is only getting 25MHz
Any ideas on how to use it with higher frequencies?
