Is anyone installed and running HA on a Odroid HC4? Is it the same as Odroid C4?
Yes, I have managed to do that after 4 hours long fight. This probably won’t help you anymore at this point, but for anyone else struggling with this.
Use the OS for Odroid C4 during the installation as it is almost identical. There is however one extra step. After inserting the microSD card into your Odroid and before you power it up, you have to press and hold little button at the bottom of the Odroid while you plug in the power cable. That button is boot switcher which tells the Odroid to boot from microSD card as it will not do that on it’s own and thus fail to start up the system.
