Hi Team,

  My customer reported an issue that while removed the CLA warning followed by below e2e post,  the CLA task couldn't be triggered.  but while kept the CLA warning, the CLA task can be triggered.

https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/684187

 Could you kindly give suggestion for removing CLA warning but also keep the CLA task running?

 Attached shown more details.

 Expect for your reply, thanks.

Best Regards

    Hi Benjamin,

    The customer should check that the same vector address is written in both cases to the MVECT registers. My suspicion is that when attempting to remove the warning the type conversion was not handled properly and incorrect vectors are being written.

    Please confirm.

    Also, the E2E post suggests to use a #pragma to suppress the warning. The customer is not doing this, but is instead doing some type conversions which are lilkely not working properly.

    Please try this and it should get to working again.
