This defines maximum number of areas located on flash. Each area can be erased without affecting other areas thus the size of area can affect performance of GC where single area has to be rewritten. At least one scratch and one non-scratch area is required.

Direct dependencies¶

(Includes any dependencies from if’s and menus.)

Defaults¶

8 if FILE_SYSTEM_NFFS && FILE_SYSTEM
