Information about Virtual Flash Page allocation

[Yahya Tawil]

Hi 

I'm little bit confused about how FDS library allocate the virtual flash pages (according to the number and size in sdk_config.h). 

I decrease the number of virtual pages number and rebuild the code, without noticing change to code size.

I failed to find a documentation describing the process. Should the linker file .ld changes according to number of pages? if yes, what is the origin address ? 

Thanks

The other confusing thing is: printing logs from pages_init() from fds.c shows that virtual pages address is: 

For 2 virtual pages: 0x0007e000 and 0x0007f000 which are belongs to "Bootloader settings" and "MBR parameter storage" 
For 3 virtual pages: 0x0007d000, 0x0007e000 and 0x0007f000.

The other thing to think of ... are these pages has any thing in common with application data area mentioned here:

infocenter.nordicsemi.com/index.jsp

I use NRF52832, SD 132 V4.

Hi,

Flash space used by FDS is not allocated by the application. Please see fstorage Initialization documentation, and make sure you understand the Note.

Best regards,
