FDS lifetime

[Challen]

Hi, I use SDK13.1 FDS example and have some questions about that. Is there any influence about the lifetime of Flash when i use FDS function to write and delete the records.If it has,how to calculate the lifetime of Flash.Thanks.

I get the FDS_ERR_NO_SPACE_IN_FLASH error when trying to write to flash, then call fds_gc() ，the FDS callback return FDS_SUCCESS ，but when i write to flash again,still FDS_ERR_NO_SPACE_IN_FLASH ,why?
