Hi, i have been writting driver for mpc5200b MSCAN device. I want CAN1 send data to CAN2. I set all the MSCAN ID Mask Registers of CAN2 to 0xFF. But CAN2 can not receive any data from CAN1.There's even no any Receiver Full Interrupt(I can assure I enabled it).
I think CAN1 send data successfully, because I always check MSCAN Transmit Error Counter Register of the CAN1, it is 0. And I always recieve Transmitter Buffer Empty Interrupt from CAN1 after I send data out.
I have looked up every materials as possible as I can. But I still can not understand why CAN2 can not get any data.
Please give me some help if you know.
