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?

Thank you Sigurd! You guys really should add this example (rar file in the post above) to the FDS GitHub example. I spent a lot of time trying to get that SDK 11 example to work on SDk 12.x - lots changed between those versions and this updated example helps!

Hi, I have downloaded the SDK 11.0 FDS example from GitHub. It contains both the fstorage and pstorage . Does not FDS rely on fstorage? I am using peer manager not device manager in my application.

Also in compiling the code I get an error; device_manager.h not found. Looking for your help

Hi Akram,

Yes, FDS uses fstorage. Are you using SDK 11?

[Akram Karimi]

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
