Hello, today I updated my BananaPi, after a reboot, I don't have a video-output.. the BPi is connected via HDMI to a NEC 55" Monitor.. LAN-cable is plugged in and it gets power via a powersupply.. any suggestion how to solve that? X11vnc works fine thanks! Linux bananapim2 4.9.12-sunxi #4 SMP Thu Feb 23 19:46:51 CET 2017 armv7l GNU/Linux

sorry but any other idea?

so, now i tried a G.SKILL HC1 32GB micro-sdcard (instead of a SanDisk Ultra HC1 16GB) and it is the same, it is in a reboot loop.. the last few lines that i can see are in the attachment..

hehe , yes maybe but now it boots, but after a few minutes it reboots.. but i will try also a new micro-sd-card (tomorrow)

hmm maybe i'm to stupid, but now it don't boot because of some files are missing?! (see screenshot)

Hi Igor, thanks for that.. i see you create a Xenial Desktop Image? I will try this tomorrow morning..

Hello, i want to try armbian, so I download it from here https://www.armbian.com/banana-pi-m2/and write it to the sd-card. i started the BPi M2 login as root create a user account and the Desktop started .... ehm NOT.. it runs in an infinity reboot loop.. if I disconnect the LAN-Cable i will see the desktop, but after a few minutes the same.. so i remove the HDMI-cable.. it boots, i plugged in the LAN-cable and can connect via ssh.. i try to upgrade the system, but again after a few minutes it freeze and reboot. can somebody help me to figrue out what happen and how can i resolve this problem? thanks in advance!
