s12zvc can communication error

[sypark]

Hello I am implementing can communication.

I'm not good at English and I use Google Translator.

I am using s12zvc 64mkh, codewarrior11.0.

CAN_test3.zip source code is good for sending and receiving communication.

The DevKit-S12ZVC_IIC_Lab4.zip source code build OK. but run error.

If disable void interrupt VectorNumber_Vcan0rx CAN_ISR ()(CAN.c file), the run will work without error.
If it is active, an error occurs.

When CAN_ISR () is disabled, send is sent but not receive.

Why is this happening? What is the solution ...?

please help me.

Thank you.

Hi,

The problem is that the example is build using Processor expert which generates its own vector table. And since the CAN module is not configured by PE, the vector is occupied by CPU_Interrupt routine by default.

Then, the programmer writes twice to the same vector in Flash  (0xFFFE10 - 0xFFFFFB).

Regards,

Daniel
