Hi all
i use the stm32H735IGKx demo board,and would like to configure the can speed 500k. Below is my configuration:
but i can't get the can data from the third party software at 500Kbps
and when i use the oscilloscope, i have to configure 800Kbps that i can get the right information:
and when i configured like below, i can get the right can data
is there something wrong?
looking for experts' reply, many thanks.
Solved! Go to Solution.

It seems the clock configuration problem
before, I used PLL2Q. no matter how I changed the PLL2Q, it seems the clock is around 20MHz
after, I changed clock to PLL1Q, the problem solved and FDCAN module worked very well.
the reason I don't have time to find, maybe later.
