Marks internal flash memory nordic

[Fyodor Prokopovich]

Hi, how i can mark internal flash memory nordic for user data and logs, and protect them from being overwritten when updating firmware over the DFU?

Thanks!

Hi Fyodor, 

You can configure the area that the bootloader should not erase when doing DFU by assigning APP_DATA_RESERVED size. Please have a look at the memory layout at the bottom of this page: https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-3-0/lib_bootloader?316#lib_bootloader_memory
