FDS SDK13 and Memory Allocation with SES

[RichieJH]

I have been working on integrating FDS into an SDK13 project using SES v3.24.

I'm not sure if the memory allocations are set correct. If I increase the FDS_VIRTUAL_PAGES from 3 to 100 I would have thought I would see increased .fs_data usage in the Memory Usage tab in SES for FLASH, in particular 100 pages at the end of the FLASH memory even though I haven't used them - I would have thought they would have been set aside.

Yet all I see is this:

My flash_placement.xml is in line with the SES tutorial. My Section Placement Segments are :

FLASH RX 0x00000000 0x00080000
SRAM RWX 0x20000000 0x00010000

My Section Placement Macros are :

FLASH_START=0x1F000
SRAM_START=0x200025F8

I am linking in SD 132 4.0.2.

This is an nRF52832 QFAA chip.

Is this correct does anyone know?

.fs_data is where the variable describing the flash storage is set, look at the location, it's in RAM, not flash. So no it won't change.

I see, but just so I understand, are you are saying the compiler has no way of knowing how many flash pages are being allocated therefore cannot indicate it in the dashboard?

[RK]

no way for it to know, not in a placed segment.

Got it, thanks.
