Try to run example flash_fds example on Nordic DK(10056), but meet

Hi Support, 

This issue happens in nRF5_SDK_16.0.0_98a08e2  and nRF5_SDK_15.3.0_59ac345.  

Directly import the example from SDK (examples\peripheral\flash_fds) into SES, build it and download to Nodic DK(10056). According to a serial port console, I could read, 


<info> app: FDS example started.
<info> app: Initializing fds...
<error> app: Fatal error
<warning> app: System reset
<info> app: FDS example started.
<info> app: Initializing fds...
<error> app: Fatal error
<warning> app: System reset

(repeating)

In debug tracing mode, I could find that the failure happened in ,

fds_init_opts_t init_opts = pages_init();

switch (init_opts)
{
case NO_PAGES:
case NO_SWAP:
return FDS_ERR_NO_PAGES;

I know there is a discussion in this forum 4 years ago, https://devzone.nordicsemi.com/f/nordic-q-a/13672/fstorage-memory-allocation-in-segger-embedded-studio/52240#52240

Just thinking if I could get a latest complete instruction (but not piece by piece) for such an issue? if any explanation, it would be better.

Thanks a lot. Attachment is my flash_placement.xml. Furthermore, I could read the elf file as well, partially attached here.
