    Hi Angela,

    Can you please confirm from customer if this is using the CAN bootloader kernel?  Also can you please translate the attachment?

    Thanks,

    Joseph

    Hi Joseph,

    You can ignore the bootloader, he just program .out file through emulator and use CAN communication tool to modify some variables. The attachment name is not important, the content of attachment is the cmd file.

    Hi Angela,

    So if I am understanding the problem correctly, the basic issue is that CAN is not sending correct data?  Can you please give more details to understand the issue better?

              - What is the setup used (launch pad, control card, custom board??)

              - What is the baud rate

              - Are other variables updated  through CAN?

              - Can you ask customer to look at the error registers like CAN_ES when the problem happens?

    Regards,

    Joseph
