Protect flash region from FDS

[Jim]

Hi,

So I have a HEX file with unit specific data that I upload to 0x00062000. This data is about 80kb so it leaves some space incase I need a bootloader in the future.

Furthermore I store some data generated from device usage with the FDS. Everything works fine for now but how can I trust that the FDS and/or a program image (thats too big) overwrites this region?

I know that the FDS marks the pages with 0xDEADC0DE but is this a guarantee for not writing in my region?

I use a nRF52832_xxaa with sdk 13 and S132 4.0.2.

Thanks /Jim

FDS shouldn't overwrite your data as long as you have configured correctly.

The default setting is:

#define FDS_VIRTUAL_PAGES 3

Then the three last pages of flash will be used by FDS (as long as you don't have a bootloader).
