Configuration options for FDS.
| #define FDS_VIRTUAL_PAGE_SIZE (256) |
Configures the size of a virtual page of flash memory, expressed in number of 4-byte words.
By default, a virtual page is the same size as a physical page. Therefore, the default size is 1024 bytes for nRF51 ICs and 4096 bytes for nRF52 ICs.
The size of a virtual page must be a multiple of the size of a physical page.
| #define FDS_VIRTUAL_PAGES (3) |
Configures the number of virtual flash pages to use.
The total amount of flash memory that is used by FDS amounts to FDS_VIRTUAL_PAGES * FDS_VIRTUAL_PAGE_SIZE * 4 bytes. On nRF51 ICs, this defaults to 3 * 256 * 4 bytes = 3072 bytes. On nRF52 ICs, it defaults to 3 * 1024 * 4 bytes = 12288 bytes.
One of the virtual pages is reserved by the system for garbage collection. Therefore, the minimum is two virtual pages: one page to store data and one page to be used by the system for garbage collection.
