Hallo,
I'm testing zephyr with nrf52833. When Flashing "zephyr/samples/subsys/settings" example it fails hier is the output:
*** Booting Zephyr OS build zephyr-v3.1.0 ***
*** Settings usage example ***
settings subsys initialization: OK.
subtree <alpha> handler registered: OK
subtree <alpha/beta> has static handler
##############
# iteration 0
##############
=================================================
basic load and save using registered handlers
load all key-value pairs using registered handlers
loading all settings under <beta> handler is done
loading all settings under <alpha> handler is done
save <alpha/beta/voltage> key directly: fail (err -2)
OK.
load <alpha/beta> key-value pairs using registered handlers
loading all settings under <beta> handler is done
save all key-value pairs using registered handlers
load all key-value pairs using registered handlers
=================================================
loading subtree to destination provided by the caller
direct.length = -2305582420662946769
direct.length_1 = 2328
direct.length_2 = 536872592
=================================================
Delete a key-value pair
delete <alpha/length>: fail (err -2)
Can't to load the <alpha/length> value as expected
=================================================
Service a key-value pair without dedicated handlers
<gamma> = 0 (default)
save <gamma> key directly: fail (err -2)
