Problem with CAN 1

[David_Estevez]

Hello,

I was using a program with CAN 0 to transmit messages and it was working fine. however, when making the change from CAN 0 to CAN 1 it stopped working, no message is transmitted by CAN.
I made the following changes in Processor Expert to use CAN 1:

Remove the configuration of the CAN0 pins and configure the PTA12 and PTA13 pins.

change the device from CAN 0 to CAN 1.

What could be the problem? Some other configuration change is required.

Thanks in advance!

Hi

CAN0_TX(PTE5) and CAN0_RX(PTE4) are connected to UJA1169TK(CAN System Basis Chip), but those pins of CAN1 are not connected. You can find the information in S32K144EVB Evaluation Board Schematics.

Best Regards,
Robin
