When i try to boot from orange pi pc it doesnt do nothing, dont even flash the red and green led. the board is ok, because it works with my ubunto sd card.
Created the card with etchy and im using latest image from OctoPrint.org - Download & Setup OctoPrint
The images you can download are exclusively for Raspberry Pi boards, they will not work on other small board computers. The Orange Pi has a very different SOC and architecture, so you will need to install a normal OS on it and manually install OctoPrint on top of that.
