J721EXSOMXEVM: Encountered an issue when assigning multiple PDUs to a single HOH

Part Number: J721EXSOMXEVM

Tool/software:

Hello Team,

During the testing of CanAssist test cases which involve assigning multiple PDUs to single HOH, we encountered an issue when assigning multiple PDUs to a single HOH. Some messages were getting lost. However, when we assigned a single PDU to a single HOH, all messages were received correctly.

I have added the generated files for the CAN. Please review them and let me know if there is anything specific we need to take care of when assigning multiple PDUs to a single HOH.

Regards,

Prashant Singh Tomar

  • Hello prashant ,

    I see the configuration files entirely different.Have you generated these from TI -MCAL plugins ? Could you elaborate more on your configuration ? i believe you are using simple CAN but not CAN FD.

    Can you also share me your example custom application>?

    Regards

    Tarun MUkesh

  • Hello Tarun,

     

    This project is prepared from the TI MCAL package MCUSW_09_00_00_15_CONFIG + ti-processor-sdk-rtos-j721e-evm-09_00_00_02. As you could see in the generated files attached,the project has two Rx PDUs assigned to same HOH for BASIC CAN. However only one PDU is received while testing. When we assign individual HOHs for the PDUs we are able to received both of them.

     

    So we would like to know if there is any other configuration parameter we have to take care to allow multiple PDUs be assigned to single HOH and make it work.

    Regards, 

    Prashant Singh Tomar

  • Hello Prashant,

    Let me check your configuration files and will share my opinion on it 

    Regards 

    Tarun Mukesh
