Hi. I have a problem about STM32F105RCT7. I want to use CANBUS protocol in this IC. I sure I made the CANBUS configuration right. My problem is, I can transmit Txmessage even I can view my message on the oscilloscope.

 But I can not return my message by CANLINE. When I do the same operations in STM32F103C8T6, I can get answers from the Canbus line.I chose the stm32f105RC family to use double canbus. I can't solve the problem. Do you have any ideas?. Thank you.
