Detailed Description

Non-volatile Storage File system structure.

Parameters

offset	File system offset in flash
ate_wra	Allocation table entry write address. Addresses are stored as uint32_t: high 2 bytes correspond to the sector, low 2 bytes are the offset in the sector
data_wra	Data write address
sector_size	File system is split into sectors, each sector must be multiple of pagesize
sector_count	Number of sectors in the file systems
ready	Flag indicating if the filesystem is initialized
nvs_lock	Mutex
flash_device	Flash Device runtime structure
flash_parameters	Flash memory parameters structure
