so it was NM who gave the HC1 the dhcp-ip on the "enx001e0630cdfb"-interface, not the ifupdown-scripts. makes sense. and why was it not reachable after I added a bridge-config to interfaces (with eth0), not touching NM. that shouldn't have touched the NM setup of "enx001e0630cdfb" - right? tracing the traffic shows, that both, the fixed bridge-ip (eth0) and the NM-dhcp-ip (enx001e0630cdfb) responds to arp-packages, but not to ping or ssh. it seems to be buggy and leads to inconsistent behavior. so, relaying on NM would also mean removing /etc/network/interfaces and at least add a BFW to the other interfaces.*-files about the changed name, to make it less confusing. it left me with an headless server (HC1) which was not net-reachable. and for an server-like device, I experienced over the years, is an fixed config much more reliable then NM. just my 2cent

may I chime in with my latest experiences on self-build stretch images for the XU4/HC1: in stretch, the former eth0 get renamed to enx001e0630cdfb (on the XU4), and surly to other names on other HW. that does not happen when upgraded from jessie. see also: https://wiki.debian.org/NetworkConfiguration#Predictable_Network_Interface_Names that leads to: 1. the default /etc/network/interface config with 'eth0 dhcp' does work here somehow – but it shouldn't. don't know for other HW. 2. but setting up an bridge br0 with eth0 as interface does not work. it needs the new interface name. so it seems a little bit random and might leave one with an unreachable device. suggestion: adapt all /etc/network/interface* files with an automatic script at firstboot to the interface-name the kernel uses (i.e. in /proc/net/dev) somthing like this should do it: IFNAME=`grep en /proc/net/dev|cut -d: -f1` or IFNAME=`basename $(ls -d /sys/class/net/en*)` sed -i s/eth0/$IFNAME/g /etc/network/interfaces* same applies to wlan-interfaces

hello dear armbian developers, building jessie or stretch with btrfs-root ends up in an boot-loop. this is due to an wrong entry in boot.ini setenv rootfstype "ext4" changing it manually to "btrfs" fixed the Problem the config I used: KERNEL_ONLY="no" # leave empty to select each time, set to "yes" or "no" to skip dialog prompt KERNEL_CONFIGURE="no" # leave empty to select each time, set to "yes" or "no" to skip dialog prompt CLEAN_LEVEL="make,debs,oldcache" # comma-separated list of clean targets: "make" = make clean for selected kernel and u-boot, # "debs" = delete packages in "./output/debs" for current branch and family, # "alldebs" = delete all packages in "./output/debs", "images" = delete "./output/images", # "cache" = delete "./output/cache", "sources" = delete "./sources" # "oldcache" = remove old cached rootfs except for the newest 6 files DEST_LANG="de_DE.UTF-8" # sl_SI.UTF-8, en_US.UTF-8 # advanced KERNEL_KEEP_CONFIG="no" # do not overwrite kernel config before compilation EXTERNAL="yes" # build and install extra applications and drivers EXTERNAL_NEW="prebuilt" # compile and install or install prebuilt additional packages CREATE_PATCHES="no" # wait that you make changes to uboot and kernel source and creates patches BUILD_ALL="no" # cycle through available boards and make images or kernel/u-boot packages. # set KERNEL_ONLY to "yes" or "no" to build all packages/all images BSPFREEZE="" # freeze armbian packages (u-boot, kernel, dtb) INSTALL_HEADERS="" # install kernel headers package BUILD_DESKTOP="no" BOARD=odroidxu4 BRANCH=next RELEASE=stretch ROOTFS_TYPE=btrfs FIXED_IMAGE_SIZE=1888 should I open a bug on github for this? thanks a lot guenter

Hello Tom, sorry for late response, but the forum-sw didn't send me an email per default on reply to my thread… yes, the XU4 was on OMV, but the same thing happens with pure armbian.
