Ok. Maybe I’m gonna try balenaOS as base and put everything else in containers.
I just don’t know what to think about giving a company SSH access to my device 
I’d rather leave that away and not push stuff from balena account to my device but pull stuff from balena with my device.
Do you know if it runs on Odroid HC2 yet? I just read trough this thread:
If there’s an issue and it is not resolved I may be able to help (well…provide logs).
I bought this USB to UART kit: https://www.hardkernel.com/shop/usb-uart-module-kit/
cause I had boot problems once before…and I also managed to connect via UART to my device and get logs.
I could put it to use…maybe there is no problem at all and the user from the thread did sth. wrong…also happened to me before, when I started with sbc’s.
