Errors

Normative

The error codes a conformant watchdog driver reports. Development errors are only raised when development error reporting is enabled (see enable_development_error_reporting in Configuration Reference). The watchdog driver defines no runtime errors. Governed by CHI-WDG-MUST-06 and CHI-WDG-MUST-07 in Wdg — Requirements.

Development errors

When development error reporting is enabled, each API detects the conditions below and raises the listed error via LogM_Report with development-error level. Wdg_SetMode additionally returns E_NOT_OK when it detects a development error.

Development errors by API

API	Condition	Error id
Wdg_Init	WdgDrv already initialized	WDG_DEVERR_DRIVER_STATE
Wdg_Init	configPtr is not NULL_PTR	WDG_DEVERR_PARAM_POINTER
Wdg_SetMode / Wdg_UpdateTimeout / Wdg_FeedHw	WdgDrv not initialized	WDG_DEVERR_DRIVER_STATE
Wdg_SetMode	mode not supported	WDG_DEVERR_PARAM_MODE
Wdg_UpdateTimeout	timeout above the configured maximum for the current mode	WDG_DEVERR_PARAM_TIMEOUT
