AM2632: CANFD

Part Number: AM2632

Tool/software:

Dear Texas Instruments Support Team,

I hope you are doing well.

We are encountering an issue with the AM2632 CANFD module during development. When sending CAN data without connecting an external CAN analyzer/tool, the program becomes blocked in a loop. This behavior hinders further operations.

SDK version: mcu_plus_sdk_am263x_10_01_00_31

Could you please provide guidance on how to avoid blocking in this scenario? Specifically, we would like to know:

  1. Are there recommended configurations (e.g., using non-blocking modes, adjusting error handling, or timeout mechanisms) to resolve this?

  2. Does TI provide example code or documentation for CANFD communication in standalone environments (without external CAN tools)?

Any insights or references would be greatly appreciated.

Thank you for your support.

Best regards,

zx

    Hello zx,

    From your problem description, this issue sounds more like a hardware rooted problem. A few questions come to mind initially:

    1. How are you making the connection when not using a CAN analyzer or tool?
    2. Are you connecting it to another CAN device? If so can you describe the connection done?
    3. What CAN transceiver is being used with this - an on board transceiver or an external one?
    4. If not using an on board transceiver, which MCAN pins on the EVM are you using specifically?
    5. Which example project have you used as a basis for this - and can you re-produce this issue with an unmodified SDK example or only the CAN project you've done development with?

    Our CAN examples will work for CANFD without using external CAN tools. A properly connected system using CAN FD transceivers can be communicated with using the SDK examples without any analyzers involved.
