Nucleus Name
DS_FLASH_EraseFlfs
Nucleus Number 506
Description Erase the complete Flash File system segment in flash memory. This will erase
all non volatile data including diversity string and DV unique ID number
Technical - Initialise Flash access
- Search in flash for the segment with the “FLFS” and “FLF2” signature
- Ask the user whether he is sure to erase all data
- If available erase the sector containing the FLFS signature
- If available erase the sector containing the FLF2 signature
Important note: This nucleus will erase all data, make sure to reboot after this and
program a diversity string
Execution Time About 1 second per block erased.
User Input None
Error Number Description
50600 FLFS successfully erased
50601 User aborted the test
50602 FLFS segment is not available
Examples
DS:> 506
Do you readlly want to erase the entire FLFS ? [Y /N(Default)] :y
Erasing FLFS...
050600: All data has been erased
Test OK @
DS:> 506
Do you readlly want to erase the entire FLFS ? [Y /N(Default)] :n
