How to save data into chip flash in a easy way?

[cgha]

I want to open a sequential space for saving my data, about 20KB , and I want to modify or read it anytime, nordic suggest using FDS, but it seems a bit confusing. Is there any way that I can define a large const array in flash address and let me to manage the store and read?

You can access flash through the sd_flash_* functions.

I have make a small example here.

It is made for SoftDevice S210, but it shouldn't be hard to port it to antoher SoftDevice.

Thanks for your reply, the sd_flash_*function is enough for me to access the flash operation.
