How to use nRF9160's internal flash to store data

Question

Hi, 
 I use the nRF9160dk and I want to use nRF9160's internal flash which has 1MB flash to store a few data. But I cannot find any guideline about using nRF9160's internal flash. 
 So how to use this 1MB flash to store data? 
 board: nrf9160dk SDK: v2.5.0 
 Thanks, 
 Liza

Hi, 
 Can you look at this blog post? It lists some storing alternatives available in Zephyr,

Hi, 
 You have an overflow in your code. uint8_t type can only hold values from 0 to 255 . If you assign this 1000 then you get an overflow, which results in an incorrect value being stored. 
 Try changing this to for example 250 and see if that fixes your issue,
