systemctl disable wpa_supplicant

See https://wiki.debian.org/DebianGeoMirror On my install apt-get update yielded device or resource busy, fixed it by changing apt repository to http://deb.debian.org. weird, now it works alright

Ah great. Been trying to strip down kernel config but end up with unbootable system.

no network-manager is easy; # cat >/etc/network/interfaces.d/eth0 auto eth0 iface eth0 inet dhcp iface eth0 inet6 auto # dpkg -P network-manager wpasupplicant crda wireless-tools wireless-regdb libiw && reboot

dmesg -n 1 or something?

Add maxcpus=1 (usbcore.nousb) to kernel cmdline or e.g. echo 0 >/sys/devices/system/cpu/cpu3/online Blacklisting modules is safe; # cat >/etc/modprobe.d/blacklist.conf blacklist cfg80211 blacklist ip_tables blacklist lima blacklist snd blacklist snd_pcm blacklist snd_pcm_dmaengine blacklist snd_soc_core blacklist snd_soc_simple_card blacklist snd_soc_simple_card_utils blacklist snd_timer blacklist soundcore blacklist sun4i_i2s blacklist sun8i_adda_pr_regmap blacklist sun8i_codec_analog blacklist sunxi_cedrus blacklist v4l2_mem2mem ^D Note I do use headless, no usb no wifi no network-manager, you will need to adapt the blacklist according to your needs (board, used features).

Will build the packages to see what armbian-release is generated. armbianmonitor does not work by default as the buster distribution does not include a repository with rpimonitor, fixed that, see http://ix.io/2l7O Is master on https://github.com/armbian considered stable and used for release images?

I have a dirt-cheap psu and old phone cable powering the Zeropi and no issues. RPi2 and RPi3 are much more fuss, probably because I don't have anything on the usb. Spec recommends 2A psu, I doubt the zeropi uses much more than 1a

Running buster on a ZeroPi but softy does not uninstall. Also home-assistant does not seem to install, followed rpi3 guide on homeassistant and got it to work in docker container; Softy reports homeassistant to be installed.
