Having Issues with classic CAN on STM32H745

Hello Team,

We got our board booted up recently and Currently testing out CAN with classic mode. All our external devices support Classic CAN mode and even after configuring it with 500kps, It doesn't seem to transmit data.

Please, find the attached MX file that we use currently. Any help would be appreciated.

Are you sure? because here you are setting the CAN bitrate to 1Mb/s:
