TMS320F28384D: The CAN communication between two TMS320F28384D starts to send remote frames and I don't know why

Part Number: TMS320F28384D

I have configured a CAN communication between two TMS320F28384D. Everything works fine during a while (several minutes) but suddenly one message stop to send normal mesasages and starts to send remote frames, and I don't know why. I think that I have dissable all about remote frames: RmtEn = 0; DAR = 1;.... anything else?

Thank you

It seems that the mailboxes configured for reception starts to send remote frames with the ID of a received message, and it never stops

This can only happen when the TxRqst of a receive mailbox is set.

RmtEn is used in a Transmit mailbox to automatically respond to a remote frame. It has nothing to do with generating a remote frame. DAR bit also has nothing to do with generating a remote frame.
