Logical page size of SPIFFS partition, in bytes. Must be multiple

Smaller page sizes reduce overhead when storing small (< page size)

If this option is not set, the time field is 32 bits (up to 2106 year),
|
|
otherwise it is 64 bits and make sure it matches SPIFFS_META_LENGTH.
|
|
If the chip already has the spiffs image with the time field = 32 bits
|
|
then this option cannot be applied in this case.
|
|
Erase it first before using this option.
|
|
To resolve the Y2K38 problem for the spiffs, use a toolchain with support
|
|
time_t 64 bits (see SDK_TOOLCHAIN_SUPPORTS_TIME_WIDE_64_BITS).
