Yes, as long as you don't change FS_PAGE_END_ADDR which is calculated with fs_flash_page_end_addr().

Petter, that is currently how I have it set up, and I am starting at 0x3FC00. Will this guarantee that the memory address will always be fixed to 0x3FC00?

If you are only calling

// Our fstorage configuration.
FS_REGISTER_CFG(fs_config_t fs_config) =
{
    .callback  = fs_event_handler,
    .num_pages = FDS_PHY_PAGES,
    // We register with the highest priority in order to be assigned
    // the pages with the highest memory address (closest to the bootloader).
    .priority  = 0xFF
};

once, I think you can just set FDS_PHY_PAGES to 1, and p_start_addr should be 0x3FC00. You can however confirm this by setting a breakpoint in fs_init().
