FDS maximal virtual pages

[emb_dev]

Hello,

we have a question about the usage of FDS. The data to save has a length of 1200 words. So the virtual page size is set to:

#define FDS_VIRTUAL_PAGE_SIZE 2048

We are working with a nRF52832-QFAA which has a flash size of 512kB. How do we know the maximal number for the virtual pages that we can use?

#define FDS_VIRTUAL_PAGES ?

The goal is to know how many records of the 1200 word length can be saved?

We are using SDK 17.0.2 and Softdevice s132_7.2.0.

Hi, 

In theoretical, the nRF52832 has 64 flash pages in total if you increase FDS_VIRTUAL_PAGE_SIZE to 2048, but you would need to fit the application as well. If you set FDS_VIRTUAL_PAGES to 64, you will not have any space for the application.
