Name flashTotalSize
Description
Total flash memory size in bytes.
Host Address

Type
Integer
Attributes Read-only
Implemented Version

Name
flashSectorSize
Description
Largest flash sector size in bytes. Sector size is visible via TFTP where each sector is presented as
a system file. Some flash memories have sectors that vary in size and it is not safe to use this
variable to determine sector size. The safe way to determine sector size is to read each sector via
TFTP. The amount of data returned will indicate the sector size.

Name
flashPersistSequence
Description
Sequence number for persistence storage. This gives an approximate indication of the wear on the
flash memory from persistent stores. The sequence number is incremented each time a sector is
erased to make room for a persistent store. Typically two sectors are used for persistent storage.
The sequence number divided by the number of sectors used for persistence yields the approximate
erase cycle count each sector has experienced. Flash memory is typically rated for no less than
100,000 erase cycles.
