NVS Settings

The NVS (Non-Volatile Storage) subsystem stores operational parameters for the Carryout G2 firmware. Access it from the root menu with nvs, then use d to dump all values or e <idx> to read individual entries.

Write with care

e <idx> <value> writes values to the in-memory copy immediately. Changes are not persisted to flash until you send s (save). Any unrecognized input in the NVS submenu is treated as a sequential index read (no error string), which is harmless but can be confusing.

NVS Commands

Command	Description
d	Dump all NVS values (name / current / saved / default)
d <idx>	Dump single value with details
e <idx>	Read NVS value at index
e <idx> <v>	Write NVS value at index (not saved until s)
s	Save pending changes to flash

Note

NVS indices 72-77 configure gyro parameters, but the G2 boot log says nothing about a gyro. The G2 may share a PCB design with a larger model that includes a MEMS gyro — the footprint may be unpopulated (DNP).
