Hi, I'm trying to read CAN bus messages via stm32f4 but unable to receive any data.

The CAN bus transmit some raw data at 500Kbits/sec and is transferred via transciever to pins PB8(Rx) and PB9(Tx).I tried to configure the followed values from the cubeMx platform (since my CLK on APB1 is 42MHz): prescalar=6, TimeSeg1 = CAN_BS1_11TQ,...
