    It's a little hard to say how to resolve this. Have you looked at ROV? You can scan for errors in the BIOS module in ROV. This will check to see if any stacks are blown, etc. Is there any Log data in the logger you are using?

    What version of SYS/BIOS are you using?

    You are going to have to do a little debugging by trying to unwind the exception.  The Exception occurred at 0x97631104 according to your print so start by looking at that address and the statements right above it.

    My best guess from your print is that, there's probably a branch through a register and the register happened to contain a value of 0.

    Hi Todd,

    we are using SYS/BIOS 6.33.00.19

    And also we checked that the stacks are not blown.

    Kindly Advise where is the error?

    Thanks & Regards,

    Hi judahvang,

    When we saw the address 0x97631104 in memory browser,  it comes under ti_sysbios_knl_Task_Module_State_0_ready0_A

    Could you please advise how to overcome this, we are using SYS/BIOS version, 6.33.00.19

    Thanks & Regards,

    The symbol is data and not code so as I stated but you need to do some debugging to unwind the exception.

    Unfortunately there's not much more I can suggest especially if you've already determined that your task stacks and ISR stack is not getting blown.
