Hi all,

I have a problem with Orange Pi (normal model) : No startup, black screen. (HDMI or VGA)
- I use a 8 Go SD card class10, or a 8Go class 4: no change.
- Android or Bananian, download from here
- cheksum ok, image writen with dd in Ubuntu for Bananian, Windows for Android (PhoenixCard).
- Alimentation: 5V 1A, micro USB or round plug, no change (works with raspberry).

I have just a red led. Tried to reboot the card, pressed the button 10s. The red led is 1/2 lighted, and retry to start: Nothing at the screen.

I have also seen melted varnish around the HDMI interface, you can see the pic: is it normal?


Must I change my Orange ??

Thanks

Orange PI need to use 5V 2A charger to work properly, current startup moment can exceed 1A. please confirm it.

Ok I will try with 2A charger, I will come back to say if it works.
Thanks

PS: In the manual user of the Orange Pi, it's notified:
5. Finally, at the very left of the bottom edge is the micro-usb power
connector. Plug in a regulated power supply that is rated at 5V ±
5% and atleast 700mA (or 0.7A). Any number bigger than 700 mA
(like 1000mA) willalso work.

So I thought that 1A was enough just for boot !

Have you tried a serial debug console ?
It may raise some errors here ...

Sorry,only for orange pi mini is ok. Most of the micro USB through the PC to supply power cann't be used, orange pi  has the moment of starting current of about 1.5A. because orange pi have five usb 2.0 port with many large capacitor,In order to stable operation of USB device.

On my site (in French, but your google is your friend isn't it ) I put a page explaining how to build such cable with only 2 transistors and few resistors.
As well as the software part.

It's for BananaPI but should/may work for the OrangePI as well.

Oh, I've made a terrible mistake to write the SD card....
  1. sudo dd if=bananian-141102.img of=/dev/sdd bs=4M
Copy the Code

is the good line, not with sdd1....  that was my error.

Now, my Orange has started with 2A, and 1A too !!

My apologies, because you have changed the start guide.
Bananian & XFCE works good, RJ45 too. Anyway, no led for RJ45 ?

Thanks
