orangepi PC2 Openhab

I'm a newbee in the world of PI and hope to get some help to use the orangepi PC2 as a server to run Openhab domotic
For the moment I have installed the latest version of Unbuntu with the link I could find here on the forum and with assistance from Steven.

Now I try to install OpenHab. I downloaded the zip file ( distribution-1.8.3-runtime.zip) in the directory /home/orangepi/downloads, but cannot unzip it.

When I download Linux programs do I have to select 32bit or 64bit.
Many thanks for the support

I think I found the problem. I receive that the SD-card is full. Why I don't know.
When I check the properties, it's 3.9 gb (100%full), but the SD itself is 16 GB. How can I access the other 12 gb to install programs ?

Hi there,

I guess you would get more answers in the troubleshooting forum than here but anyway…

You need to reformat your SD card to get back the "missing" space, as said here

Later on you can go to the software manager and remove the packages one by one.

Do consider creating a SWAP file to help your OPI as well.

Good luck!

I cannot test it.
For some reason the screen is black.
Measured the voltage and the 5 and 3,3 V are ok on the board

the orange starts because at the beginning the red LED goes on and the green led flashes a few times.
I can see the orange pi that he is online ( with 2 IP-addresses whitch is also strange))

Should the HDMI output be broken or ????
Did the test with diffent screens

I thought you had an issue with the SD card?

Well, try to VNC to it to see if the HDMI is cooked or not.

Hi,
Please check the voltage at the 5V rail. Connect a voltmeter to pin2/4 (5V) and pin 6 (ground) of the GPIO header.
If it drops below 5V you need an other power supply. Most power supplies rated 5V2A are not holding a stable 5V output. This voltage drop causes the Orange PI to get stuck in the boot process and you would see just a blank screen.
I use a 5V8A power supply and other users reported that a PSP power supply works fine. If you have a lab power supply you can use that too ;)

If your power supply works fine (+5.xxV) you can connect via UART to investigate further.

Screen problem solved.
Next step, the SD-card to figure out.
