  • Hello Jim,

    Is this on one of our EVMs or your board? Note that for specific support with projects themselves you will want to reach out to your local FAE instead of posting on the E2E forums.

    Thanks,

    Hi Kyle,

    The EVM should have some symptom. I will also reach local FAE to check this issue.

    Thanks.
