Ashok,

No need to disable the CAN controller to reconfigure mailboxes.

Hi Hareesh,

Thanks for you are reply.

Please can you confirm checking any one of the bit is fine or need to check both of them to make sure new data is available.
CAN_NDAT_21.NewDat and CAN_IF1MCTL.NewDat?

If both are same what is the difference between them.

Thanks

Ashok

Yes, both are providing the same data. the NDAT_21 allows you to quickly check which message objects have new data without having to transfer the message object data into the IF1MCTL for each individual message object.

Best regards
Chris

Hi Christopher Chiarella,

Thanks for you are clarification,

In the application for new data will be confirmed using NDAT_21 and then transfer the message object into the IF2CMD.MSGNUM, for double confirm IF2MCTL.NEWDATA can be checked and the load the data into the application object. It is an ideal or expected behavior.

What I noticed in the Debug window, for particular message object NDAT_21 was set, the IF2MCTL.newdata bit is not set. Any debugging tips for further ,please let me know.

Thanks

Ashok

Make sure the right message object is being transferred to the IF2 and that the code isn't clearing the newdata. The driverlib will clear the newdata when receiving a message object with new data.

Best regards
Chris
