Detailed Description

Singleton owning the Flux board's persistent-storage namespaces.

Initialization runs before communication managers so calibration or board identity can be read early. Namespaces (at most 15 characters):

• "flux" — general application key-value
• "flux_cal" — calibration / factory tuning blobs
• "flux_cfg" — structured device configuration

App()

BaseNvs & NvsManager::App ( )

inlinenoexcept

General application storage (flux namespace).

Calibration()

BaseNvs & NvsManager::Calibration ( )

inlinenoexcept

Calibration and tuning blobs (flux_cal namespace).

Config()

BaseNvs & NvsManager::Config ( )

inlinenoexcept

Device configuration (flux_cfg namespace).

Deinitialize()

bool NvsManager::Deinitialize ( )

noexcept

Close namespaces (call after other subsystems if they may persist on shutdown).

Here is the caller graph for this function:

DumpStatistics()

void NvsManager::DumpStatistics ( ) const

noexcept

Here is the caller graph for this function:

staticnoexcept

GetLastError()

hf_nvs_err_t NvsManager::GetLastError ( ) const
