Write in flash nrf52832 sdk 11s132 softdevice

[annapalu]

Hi all,

i need to write in flash, and i try to use the example flash write of sdk. It works correctly but when i put it in my code, the writing register ( NRF_NVMC->CONFIG = (NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos);) failed.

The difference is that in my code i'm using the softdevice, how i can perform the write function in flash?

thanks, -Anna

You can't use those registers when the SoftDevice is present and enabled. I suggest you have a look at the fstorage and fds libraries.

i have looked the library. But i don't understand clearly if i can use it to write a value in a specific address of flash.

You can use the fstorage library for that, check out this page: infocenter.nordicsemi.com/index.jsp

I can use different configuration for every application that use fstorage?

Short answer: yes.

In practice, a 'configuration' is just an area of flash plus a set of functions that fstorage uses to write to that area. You can 'share' a configuration or you can use different ones, depending on what you want to do.
