Function forced_fdr::perform_fdr_if_necessary

pub async fn perform_fdr_if_necessary()

Performs a Factory Data Reset(FDR) on the device “if necessary.”

Necessity is determined by comparing the index stored in forced-fdr-channel-indices.config for the device’s ota channel against an index written into storage that represents the last successful FDR. forced-fdr-channel-indices.config is provided on a per board basis using config-data.

Errors

There are numerous cases (config missing, failed to read file, …) where the library is unable to determine if an FDR is necessary. In all of these cases, the library will not FDR.
