I configured the bootloader to preserve one page of data ( I configured #define DFU_APP_DATA_RESERVED 0x400
on the bootloader project
I also made the same thing with my project code
my userdata are located on the page above the bootlaoder (0x0003BC00
). I can read the flash and see that my data are stored. but when I perform DFU, I lose them
here the flash memory dump
what could be the issue (im using softdevice 8.0, SDK 10, nrf51822)
