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

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!
