MCU-PLUS-SDK-AM263X: J1939 support and detection

Part Number: MCU-PLUS-SDK-AM263X

Hello Team,

As per the Technical reference manual, AM 2634 supports J1939 protocol. and i am trying to analyze the same.

Could you please help me how we can detect the reception of J1939 message from the ' MSS_MCANn_CFG_IR' values. Normally Rx FIFO related values needs to be updated in the register but here it is not updating.

When I checked,  MSS_MCANn_CFG_IR values with j1939 reception is as follows,

0x2000 0280.

Please confirm the detection of j1939 message using SDK?

Thanks

    Hello there,
    Apologies for the delay in response. Can you please provide more information on your application, including the message config? (Hope you are using Extended ID config and not standard.)
    For the IR register value this is what it means: Rx FIFO1 message lost and Transmission complete.

    Thank you
