menu "Wear Levelling" choice WL_SECTOR_SIZE bool "Wear Levelling library sector size" default WL_SECTOR_SIZE_4096 help Sector size used by wear levelling library. You can set default sector size or size that will fit to the flash device sector size. With sector size set to 4096 bytes, wear levelling library is more efficient. However if FAT filesystem is used on top of wear levelling library, it will need more temporary storage: 4096 bytes for each mounted filesystem and 4096 bytes for each opened file. With sector size set to 512 bytes, wear levelling library will perform more operations with flash memory, but less RAM will be used by FAT filesystem library (512 bytes for the filesystem and 512 bytes for each file opened). config WL_SECTOR_SIZE_512 bool "512" config WL_SECTOR_SIZE_4096 bool "4096" endchoice config WL_SECTOR_SIZE int default 512 if WL_SECTOR_SIZE_512 default 4096 if WL_SECTOR_SIZE_4096 choice WL_SECTOR_MODE bool "Sector store mode" depends on WL_SECTOR_SIZE_512 default WL_SECTOR_MODE_SAFE help Specify the mode to store data into flash: - In Performance mode a data will be stored to the RAM and then stored back to the flash. Compared to the Safety mode, this operation is faster, but if power will be lost when erase sector operation is in progress, then the data from complete flash device sector will be lost. - In Safety mode data from complete flash device sector will be read from flash, modified, and then stored back to flash. Compared to the Performance mode, this operation is slower, but if power is lost during erase sector operation, then the data from full flash device sector will not be lost. config WL_SECTOR_MODE_PERF bool "Perfomance" config WL_SECTOR_MODE_SAFE bool "Safety" endchoice config WL_SECTOR_MODE int default 0 if WL_SECTOR_MODE_PERF default 1 if WL_SECTOR_MODE_SAFE endmenu
