How to retain flash memory?

[Shiju C G]

Hi,

I need to write data in to flash memory of the nRF51822 device.

I have tried to write data. When i checked memory address where i wrote data i could find that the data has been written.I viewed the memory in debug mode.

When i try to restart the debug the data is not available there.It shows FF in that location.

I tried to check it in the running mode also..The memory write is success i think, But the data is not retaining.How can i fix it?

I have attached the file which is used to write in to flash.

Thanks, Shiju C G

main.c

Edit: format, one sentence question.

The best way to access flash memory is to use Persistent Storage Manager.

Hi,

Is there any fault in the above code? I have tested it in some other project and it was working fine. Why not it is working in this code? Can you please suggest any reason ?

Thanks and regards, Shiju
