Hello,

I cannot run Openelec on my OPiPC (with 720p TV) . Tried to change script.bin but it didn't help. I burned many images with different versions using Win32DiskImager and all of them behave same way. I had no problems with Linuxes and Androids found here in the forum. All of them work perfectly. What am I doing wrong? Attached is the log from UART console:

Tried a different SD-card ?

maybe a shot in the dark, but the Opi can be very picky about it's power supply
It's not so much the power that's important (1 A should be enough) but the voltage should be at least 5V (when connected !)
I've had similar problems as what you describe with a supply that did output 5V when not under load, but as it was connected the output dropped to 4.8V

IMPORTANT NOTE: you can use a supply that outputs over 5V (eg. 9V), but in that case do NOT connect any USB devices to the OPI as they will be destroyed ! (found out the hard way)
the USB ports of the OPI are NOT protected/regulated, so your USB devices will be fed with the voltage of your power supply !

I solved this problem. It was related to SD card indeed. None of OpenElec image wanted to work from this card. But I had completely no problems with different Linux distributions and also Androids via PhoenixCard. This SD card is still in my use - no errors. So there must be a bug in OpenElec bootloader or something related. Finally I found cheap but decent Class10 16GB cards and first time I could see OpenElec
Regarding power - according to Orange Pi PC schematics all USB ports should have Zenner diodes at data lines and power. Also DC socket is secured by Zenner diode. Unfortunately there are only empty spots on the PCB From photos I can see that more expensive OrangePi models have these diodes soldered.
But I cannot complain - for $15 price it is real bargain. I have even purchased Orange Pi One and will Lite model too
