Hello Jacky,

Can you provide more details on what you are doing?

What do you mean by special data? I understand that in CAN you simply send data besides other parameters.

Can you describe your system: transmitter is imx53 with linux? what is your receiver? is also imx53?

Regards,

Ioseph

Jacky,

I think first you need to verify the whole tx and rx system is OK.

- Use the tests on the /test folder: test/can/doc/FSL-UT-CAN-003.txt. This test can help you to verify you have your system correctly. Can you tell how they are working? try 8 bytes.

- check your receiver is working correctly: try another receiver or use loopback mode on imx53 to receive the messages on a different port. Try a know working transmitter.

- What happens if you send less than 8 bytes, like 7, 6, 5, etc?

Sorry for reply so late.

The special data what I mean is when I send the data

79 78 2A 00 78 78 78 78

and the receiver can not get the last byte data.

My system is iMX53 linux ， and the receive is another platform device.
