    Hello,

    We looked at the logs and notice that FW has run into some problem and this is why we are seeing the dump here. The FW error triggers a HW recovery and the system does seem to recover and continue. Is this correct? We presume that you are seeing these logs but it is not crashing the system. The recovery logging only lasts for under 2ms. Are you seeing any visual problems?

    Can you please help answer the following:

    1. Does this happen on all SoC samples or only one or two (or a few)
    2. What is running in the system when the issue happens? Is there anything is different?
    3. Is there a way to reduce the time it takes to see the problem?
    4. Is there a test that can reproduce this issue on our SDK + EVM?

    Regards

    Hemant
