CAN module failure after 7 hours

Question asked by Alejandro Clerici on Dec 3, 2013

Hi, I'm having a problem with a MC9S08DZ32 CAN Module. After reset it's working fine, the messages are sent and received alright. But in some cases after 2 hours or in other most frustrating over 7 hours, the CAN module send an incorrect message. After the first failure, the error rate increase to an a half of hour.

The message is hardcoded (avoiding some variables problem). And all the precaution has been considered.

I have working with CAN in a lot of project using another manufacturer and it's the first time that I have a problem like this.

Maybe you know about a similar problem or errata...

 

 

Thanks!
