Hello Shawn,

You need to help me with which version of firmware you are using.
Also, for which async event are you collecting this message?
Are you getting any other failure async events?

Regards,
Saswat Kumar

Hi Saswat,

The SDK is 03060200 LTS. We don't notice other failure async events.

Shawn

Hi Shawn,

Can you please share more information about this?

Is this on an EVM or custom board?
Specifically which binary file is flashed and running on the device?
Was the device working before and suddenly the CPU fault occurs?

Best Regards,

Josh
