Hi,
Hassio newbie here. I have a raspberry pi 3 running HassIO and was prompted to update the operating system from 3.9 to 4.6 yesterday. After the update, hassIO doesn’t load anymore, and instead gets stuck repeating 4 different lines over and over again every 5-10min. The lines are:
‘brcmfmac: brcmf_cfg80211_set_your_power_mhmt: power save enabled’
‘IPV6 : ADDRCONF(NETDEV_UP): wlan0 : link is not ready’
‘Under-voltage detected’
‘Voltage normalized’
I have tried replacing the power supply with no avail. Is my SD card now corrupt? If so, is there a way i can recover my config files even though i didn’t do a backup recently?
Thanks in advance
How much Amps is that power supply and is it 5 Volt? A quallcom quickcharge doesn’t work, so if it is one of those it might be the issue.
It’s a 5.1V power supply designed for raspberry pi but not the official one. What’s weird is that it has worked flawlessly for the last 2 years and only suddenly did this yesterday. I’ve tried other power supplies too. Do you know a way to recover my config?
Your config is on the sd card, so you could plug that in every card reader and read it (from a Linux / Unix based system).
Power supplies aren’t made of high quality components these days, so it could be it is die-ing after two years. Though it’s weird you get the same with other power supplies. It could also be the sd card is die-ing, have you got a spare SD card? Maybe try that with a clean HA on it and see if it works, then try recovery of the config from the old card if it works again.
I’m super confused now since i took a spare SD card, flashed a new version of Hassio onto it and it still gives me the under-voltage warning but if i try and flash other software like Raspbian, it works fine with no voltage warnings. Is there something wrong with Hassio or is it more likely something wrong with my pi?
