How do I calculate the start address of fstorage?

[Ted]

I found end of address of fstorage from macro of "#define FS_PAGE_END_ADDR (fs_flash_page_end_addr())". But I want to change the start address of fstorage. Which macro or function I can modify?

The start address of Fstorage depends on how many configurations you have registered, and how many pages you have in each of the registration. But if you decrease FS_PAGE_END_ADDR with one page size you will also decrease the start address of the first configuration with one page size.
