|
|
This alert is reported when at startup, before reporting the previous error with the reset reaction, ErrorHook was called again because of an error in a partition which is configured to handle such errors with immediate safety reset. This error ID will show the last problem which caused the invocation of the ErrorHook with reset as the partition reaction.
|
ErrorHook was called again because of an error in a partition which is configured to handle such errors with immediate safety reset.
|
EPAS reset.
|
No
|
|
|
This alert is reported by the ExceptionHandler_TC3x (EXCH) component when there is a single-bit or multi-bit (all 1 and all 0) error in the pflash. This diagnostic is the handling of the exception thrown by the PFlash ECC when it encountered a multi-bit Flash fault.
|
When PFlash ECC encountered a multi-bit Flash fault. EPAS application component ExceptionHandler detected unrecoverable memory failure (PFlash ECC fault).
|
EPAS reset.
|
No
|
|
|
This alert is reported by the OsErrorHandler_R12(OSEH) component when before reporting the previous error, ErrorHook was called again because of an error in a partition which is configured to handle such errors without requesting immediate safety reset.
|
If any OS service returns a StatusType value other value than E_OK. Reported if while processing OS error occurred in QM partition one more OS error is detected.
|
EPAS reset.
|
No
|
|
|
This alert is reported by the StartupCauseProvider_R12 (SCP) component if it determines that the startup cause is a safety reset.
|
EPAS determined that the startup cause is a safety reset.

|
|
This alert is reported by the OsErrorHandler_R12(OSEH) component when ErrorHook was called because of an error in a partition which is configured to handle such errors without requesting immediate safety reset.
|
If any OS service returns a StatusType value other value than E_OK. Reported if OS error occurred in QM partition. It's a reversible error that is reported upon detection of OS error and immediately cleared to catch and indicate further errors
