How to read flash after power off/on for nRF52?

[Chaw]

Hi, Nordic

I need write some information to flash, then power off and power on, nRF52 still can read previous information. But now, nRF52 can not read, maybe ESB is still working.

I check your example in SDK (flash write）, no same demo.

Do nRF52 can support this? How can I do?

Hi,

Take a look at this FDS example. The FDS(Flash Data Storage) module provides a simple flash file-system. The module is based on fstorage, and abstracts away the lower levels of fstorage.

Update: Added FDS example for SDK 12.2: nRF52-fds-example.rar

Yes I am using SDK11. Actually I commented out the following

#include "device_manager.h" ... extern dm_application_instance_t m_app_handle;

from ble_advertising.c

and it compiled ok. Seems like, it's a added in the file by mistake which gives compile error. Although I have not tested the flash storage yet. Can you please tell me convenient test cases using which I can test the flash storage functionality. Thanks
