Fstorage/FDS Issue With SoftDevice

[george]

Hi All,

I am trying to implement fstorage (the issue also happens if you try FDS). I'm using gcc and when I modify the makefile to compile fstorage it requests a file called, "section_vars.h" which is in a folder marker as "experimental". If I include this folder with section_vars.h in it will compile. However, if I try to program the device it says, "This hex file has data in SoftDevice Region...".

I am assuming this file is altering the start address (0x1c000) of the FLASH Application section but am unsure how to change it. Or is it something else?

Any help would be highly appreciated.

Hi George,

Most of our example in the SDK v11 used the fds (for peer manager). Have you tested them ? I guess there was some thing wrong in the configuration that the hex file has something written to softdevice region (0x00 till 0x1C000)

I also made a simple example of fds here.

Hi,

I am guessing you are using a wrong linker script, or no linker script at all. Section Variables require a linker script to work with GCC. Check out the GCC linker scripts which are beside the Makefiles of the SDK examples (the extension is .ld).

I saw your example and downloaded it. Thank you for providing it. I had the same issue with FDS as I did with Fstorage. It gives me the same programming error that I am interfering with the softdevice region.

Agreed. I did check that but it seems like the memory is set up correctly. But maybe I missed something? Here is the linker file below:

I haven't edited anything dealing with the linker in the default Makefile. But I do see where it uses the file: nrf51422_xxac_s130: LINKER_SCRIPT=experimental_ble_app_blinky_gcc_nrf51.ld

/* Linker script to configure memory regions. */

SEARCH_DIR(.) GROUP(-lgcc -lc -lnosys)

MEMORY { FLASH (rx) : ORIGIN = 0x1c000, LENGTH = 0x24000 RAM (rwx) : ORIGIN = 0x20002800, LENGTH = 0x5800 }

SECTIONS { .fs_data_out ALIGN(4): { PROVIDE( __start_fs_data = .); KEEP(*(fs_data)) PROVIDE( __stop_fs_data = .); } = 0 }

INCLUDE "nrf5x_common.ld"

Any thoughts or suggestions?

@George: Could you try to download fresh SDK .zip and then try to compile an example, for example ble_app_proximity ? It should work out of the box.
