undefined reference to `__fs_data_load_start__' on ble project

Tarik

Hi,

I am trying to use Segger embedded studio for my project,

I get these errors:

Building ‘ble_app_uart_c_pca10028_s130’ from solution ‘ble_app_uart_c_pca10028_s130’ in configuration ‘nrf51422_xxac’
  Generating linker script ‘ble_app_uart_c_pca10028_s130.ld’
  Linking ble_app_uart_c_pca10028_s130.elf
    Output/ble_app_uart_c_pca10028_s130 nrf51422_xxac/Obj/thumb_crt0.o: In function `memory_set':
    undefined reference to `__fs_data_load_start__'
    undefined reference to `__fs_data_start__'
    undefined reference to `__fs_data_end__'
Build failed

I followed all steps of this blog post: devzone.nordicsemi.com/.../

and here is my flash_placement.xml file:
