`FLASH_PAGE_LAYOUT` has a hardware dependency on `FLASH_HAS_PAGE_LAYOUT` which is not present for all boards. Forcing this symbol to `y` when the hardware doesn't support it results in build errors at the Kconfig stage. `FLASH_PAGE_LAYOUT` is enabled by default when `FLASH_HAS_PAGE_LAYOUT` is true, so this change will not require any user changes.

Enable Non-volatile Storage cache, used to reduce the NVS data lookup

time. Each cache entry holds an address of the most recent allocation

help

Enable a CRC-32 on the data part of each NVS element.
|
|
The ATE CRC is not impacted by this feature and stays the same.
|
|
The CRC-32 is transparently stored at the end of the data field,
|
|
in the NVS data section, so 4 more bytes are needed per NVS element.

Enable automatic initialization of a NVS on a memory region that does
|
|
not contain a valid NVS. A region containing an invalid NVS can be
|
|
caused by corruption or by providing a non-empty region. This option
|
|
ensures a new NVS can be created.
