problem with CAN on EVB9S12XEP100

Hello,

I have EVB9S12XEP100 and I am using MSCAN. It was ok and I was able to send and receive CAN messages very well.

But now I have a problem : there isn't any signal on CANH, the signal is right on CANL (CAN0H and CAN1H are linked, CAN0L and CAN1L too, to have ACK). I have an interface CANUSB that doesn't see anything on the bus.

I have noticed that there isn't any signal on TX and RX on the MCU for MSCAN0 and MSCAN1.

It is the same code I was using before and was ok. all the other things are ok.

 

what could be the problem ?

 

Thank you for your help.

the EVB9S12X has 2type of tranceivers for SJA1054 , you can only use the LowSpeed Mode( lower than 125Kbps )

 

you can use HS mode on CAN2
