Any help in understanding size of cache memory which is used in below structure.
FF_IOManager_t *FF_CreateIOManger( FF_CreationParameters_t *pxParameters, FF_Error_t *pxError );
This FF_IOManager_t object has variable ulMemorySize, whose description says that it shoud in mutiple of sector size.
/* The size of the cache memory. ulMemorySize is specified in bytes and must
be a multiple of ulSectorSize. */
I have STM32476-RG Nucleo board with 128 KB RAM, In which I have created 25KB ramdisk so I would to cache memory size as minimum as possible.
What is recommended size for cache memory size ?
What shoud be criteria to decide apropriate size ?
