Help Instructions
Device/System Information:
- Device Type - selects the type of device (for
NAND, if TargetNDM used, select NAND NDM)
- Block Size - device block size in kilobytes
- Page Size - device page size in bytes
- Number of Blocks - device number of blocks
- Max. Bad Blocks - maximum number of bad blocks
on device (NAND devices only)
- FILENAME_MAX - system wide maximum file name
length
- FOPEN_MAX - system wide maximum number of open
files
Volume Information:
- Volume Type - selects type of volume (FFS,
FAT, ZFS). For SD/MMC/CF, only FAT is available
- Volume Number of Blocks - number of blocks
for this volume
- Volume FOPEN_MAX - volume maximum number of
open files (if 0, defaults to system wide value)
- Avg. Number of Files/Dirs - Average number
of files/directories on volume (FFS and ZFS only)
- Avg. File/Dir Name Length - Average file length
in bytes on volume (FFS and ZFS only)
- FTL Driver 'part_bytes' - FTL per block partition
bytes - the bigger this value, the faster the FTL lookup is on a page miss(FAT with
flash FTL only)
- FTL Driver 'map_size' - FTL number of RAM page
mappings - if all pages are mapped in RAM, FTL lookups are instantaneous (FAT with
flash FTL only) - setting this to 0 or bigger than volume pages maps all pages in RAM
- FTL Driver 'cached_pages' - FTL NDM number of cached
map pages - a map page contains virtual to physical mappings - the higher this number
the better performance - typical values between 1 and 10
