Flash storage in nRF52 using nrf connect sdk

[Sunil vignesh]

Hi,

I need to store the 1kB of data in the flash storage and it need to be read anytime and change the data anywhere.

I am using nrf52840 DK and also nrf5340 DK to perform these Flash storage

I found the example code in this link

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/reference/storage/nvs/nvs.html?highlight=flash%20storage

and i have tested the code.

I have difficulty to change the data storage address. where we need to change the starting address. size of flash storage. If i use DFU how to assign the flash storage

Hello,

have you looked at the Zephyr NVS sample, located in zephyr\samples\subsys\nvs? You can set the starting address by modifying the nvs_fs struct. I'm not sure that size is something that can be set statically.

 

If i use DFU how to assign the flash storage

 I'm not sure what you mean by this.
