nvramManualUpdateBackground

Function

Starts a manual update of the NVRAM content.

Syntax

uint32 nvramManualUpdateBackground(void)

Description

This function starts a manual update of the NVRAM content. Manual update has precedence over the automatic periodical update. Thus, a potentially running periodical update is aborted. But if cyclic update is on the way (the Idle task is interrupted by a preemptive task with the call of this function), start of manual update is impossible This function returns immediately, because the update is running in the background (Idle task). The completion of this process can be tested via the function nvramCheckRunningUpdate().

Note
It is not recommended to use this function when automatic update is enabled.

EC_NVRAM_FATAL_ERROR

EC_NVRAM_OVERFLOW
