Dear MathWorks Team,
I am currently programming a TI F2838x processor using Simulink. For External Mode, I am using XCP on CAN and have selected the CAN-A module.
However, CAN-A is not solely used for XCP communication — I also use it for standard CAN communication with different message IDs. XCP works as expected, and I can monitor variable values via the A2L file without any issues. That said, I have encountered an intermittent issue on the CAN bus: occasionally (approximately every 2 hours), a message appears with the same CAN ID as one of my existing fixed-length (8-byte) messages, but with a different data length.
This behavior should not occur under normal circumstances. I have reviewed my XCP configuration and everything appears to be correctly set up. Additionally, I have ensured that no mailbox number conflicts exist between the XCP configuration and my other CAN messages.
I would appreciate any insights or suggestions as to what might be causing this unexpected behavior. Has anyone encountered a similar issue, or is there any known limitation or configuration detail that I might be overlooking?
Thank you in advance for your support.Dear MathWorks Team,
