Guys,

Is it possible for me doing CAN loop test

so the output from CAN, CAN TX, I connect back to CAN RX

The code in STM32 :
Code: 
GPIOB->CRH |=  (0x08<<0);                       // CAN RX pin PB.8 input push pull 
GPIOB->CRH |=  (0x0B<<4);                       // CAN TX pin PB.9 alternate output push pull

Thanks
