Tool/software:
During thermal cycling tests, an unhandled exception occurs with the sensor under the following conditions:
Test Procedure:
The sensor is subjected to a temperature cycle from -40°C to +85°C, repeated three times.
Observed Behavior:
After the third thermal cycle, the sensor consistently encounters an unhandled exception. This behavior suggests a potential issue with temperature-related stress or improper exception handling in extreme thermal conditions.
Our investigation:
During debugging when extracting traces to find the issue right before the exception, we found out that there is a HW interrupt that occurs in the shutdown sequence and hence the exception.
Expected Behavior:
The sensor should operate normally throughout the temperature cycling without triggering any unhandled exceptions.
Request:
Please investigate the root cause of the exception and advise on corrective actions or similar issues with same SOC batch
