Hello Vagrant After my test with Armbian at Bananapi M3, i have an idea what happens. Is it possible, that the axp20x module is missing in the installer kernel? In Armbian-Syslog, i found the entry: https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=914813;filename=syslog-armbian_20.02.1_Bananapim3_buster.log;msg=100 > Feb 17 09:43:16 localhost kernel: [ 2.928297] axp20x-rsb sunxi-rsb-3a3: AXP20x variant AXP813 found In the latest Debian installer syslog, such kind of entry is missing: https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=914813;filename=uboot-2020.04.rc5.log;msg=95 Thank you for support. Bernhard
