Are there any resources for accessing the XIAO NRF52’s NVS (non-volatile storage) in Nordic Connect SDK? I’ve tried to load Nordic’s NVS sample onto it but it makes the board unresponsive (it doesn’t show up in device manager anymore so I can’t access it in terminal to see if it is working or not). Reloading the blink sample fixes it so it isn’t detrimental.
I’ve just taken the sample and made a build configuration for the BLE SENSE board. I’m not sure if there’s anything extra I should be changing to make this work.
I’d just like to save ~8 hex digits across a power cycle if possible, nothing too fancy.
Yes there is posts and examples here for things like the boot counter (saves the number in NVS and reads it on reboot) I think that’s what you want. I just posted and example in another thread that includes it, Have a look at that code and see if it’s a FIT!

What was the build configuration in NRF_SDK You can’t use the system build to make it , The bootloader in Not setup for it.
So the method is what matters with this , check out the video on Dev academy too,But you generate the config but not build it(check-mark)
Open the Kconfig and select the bootloader options and you still need to create a partition configuration . pm_static.yml file for the flash as it relates to the bootloader.If you have the DK board the examples lay it out and pretty sure there is a MCUBoot setting or demo too. Between the Kconfig and build config it just works…
The examples I was referring to , are the boot counter Examples where it takes advantage of the RTC NVM , use the search term "boot counter " to see those and others.
They are Arduino Examples but the principle is the same in NRF_SDK.
