I have the autopi connected to raspberry pi 3 through a RPi3 adapter and powered on using a 13.5 V OBD connector power supply.
I am constantly seeing Undervoltage_detected text when the pi boots up and a yellow lightning bolt sign flashing on the top right of the screen which also denotes the same.
Any idea why this is happening or how to work around this?
What type of power supply are you using? Depending on what additional equipment you have connected, you need to use a power supply with more the 2A supply.
I use power supply with 15V/2,67A and I had the same problem after upgrade to RPi3. I “solved” it by:
avoid_warnings=2
in the file /boot/config.txt
But you have to change this value every update because when update AutoPi core the file /boot/config.txt is replaced to default. This is one of disadvantage of the AutoPi. You cannot persistent modify configuration files. I had to write a script which keep changes in configuration files that I want to keep modified (e.g. iptables, /boot/config.txt, /etc/hostapd/hostapd_uap0.conf, /etc/modprobe.d/ipv6.conf(bak), /etc/dhcpcd.conf, /usr/bin/qmi-manager, /etc/sysctl.conf and so on:slightly_frowning_face:)
