I used nRF52840 board with SDK 17_1_0 ,
Using FDS I am able to read and write data into flash when nRF52840 board Continuous ON,
But when i Make nRF52840 board Power OFF and ON after FDS is not able to find out existing Record
and not able to read existing write data,
so what i can do when nRF52840 board Power OFF and ON at that time FDS data was not erase?
