Detailed Description

Defines types and macro constants used by Tasks.

Macro Definition Documentation

DISABLED

#define DISABLED   (0U)

Used to disable optional Task features through macro configurations.

ENABLED

#define ENABLED   (1U)

Used to enable optional Task features through macro configurations.

FOREVER

#define FOREVER   true

Allows testing of infinite while loops by replacing the definition during testing.

Typedef Documentation

rstCallback_t

typedef void(* rstCallback_t) (resetInfo_t resetInfo)

Defines a function pointer type for a reset handler callback function.

The function pointer type is used to configure which callback to issue for handling reset reasons in T_HandleResetReason.

Parameters

resetInfo

The reset information passed by the Task for application specific reset handling.

Enumeration Type Documentation

errInjectReset_t

enum errInjectReset_t

Defines possible reasons for a device reset due to an error injection.

This enum is used by several tasks to store possible reasons for a device reset due to an error injection in persistent memory. See T_DetermineResetReason, T_RunResetDiagnosticFsm, T_HandleResetReason and T_HandlePreStartupErrors.

Warning

It is assumed that ERRINJ_RESET_NONE is zero to ensure it is the default value when persistent memory is cleared in software or due to a Power-On Reset (POR) or Brown-Out Reset (BOR).

Warning

It is assumed that ERRINJ_RESET_CORRUPT is the highest value for data validation and that the enum value only requires 2-bits of storage in persistent memory.

Warning

Each reason value is encoded using a specific bit pattern as an additional safety measure such that a single bit flip in the data will not cause infinite reset loops.

Enumerator
ERRINJ_RESET_NONE	0b00 Device reset was not due to an error injection
ERRINJ_RESET_CPU	0b01 Device reset was due to a CPU lockstep error injection
ERRINJ_RESET_WDT	0b10 Device reset was due to a WDT expire error injection
ERRINJ_RESET_CORRUPT	0b11 The stored device reset reason is corrupted
