Hello.
Currently, I use S32 design studio to development MPC5746B.
But, I have some trouble.
To explain my current development environment(Processor Expert).
1. Add Can_pal (Ch0 ~ Ch2)
2. Can0 ~ Can1 : CAN (High speed)
3. Can2 : CAN FD
4. CAN Ch0 ~ 2 enable Tx, Rx, Bus off Interrupt.
5. CAN0 - Rx : mb 0 ~ 31, Tx : mb 32 ~ 64 (Tx, Rx bus load between 5% and 15%)
6. CAN1 - Rx : mb 0 ~ 31, Tx : mb 32 ~ 64 (Tx, Rx bus load between 1% and 3%)
7. CAN2 - Rx : mb 0 ~ 31, Tx : mb 32 ~ 64 (Tx, Rx bus load between 80% and 90%)
When i used Can0 & Can2 , I can communicate without problems.(Include Tx, Rx, BusOff Interrupt)
BUT
When i used Can0 & Can1 & Can2, I have big problems!!
if CAN1 Line disconnected with CAN Interface, CAN1's & CAN0's Busoff interrupt occurs (Confirmed via T32.).
So CAN0 also cannot communicate.(CAN0 & CAN1 BusOff state)
I don't understood whether the state of CAN1 affects CAN0.
Why? ...
I have to solve this problem to keep my project schedule.
Thank you.
