ArduPilot parameters' file location on Navio2

Been searching but cannot find any info regarding APM settings storage in Navio2.

Today I experienced that all PID setting are lost and set to default settings. Every other setting was still there.

Question is: Is there a settings file where all APM settings for the drone is stored? Want to take a backup of this file every time I boot the RPi3


Sure. It’s stored in stg files /var/APM/. For example ArduCopter.stg for copters.

You’ll be better off downloading them from GCS (“Load parameters” or something like that in Parameter List).
