Reboot loop with rainbow screen

Hey guys

 

I'm new to Rasplex so go easy on me :)

 

I installed rc2 a couple of weeks ago to give it a try and had these sorts of problems, have now installed rc3 and getting pretty well the same thing.

 

When I fire up Rasplex on my Pi, it just goes into a reboot loop with the rainbow screen flashing up constantly, never gets any further than that.

 

In the background just after the rainbow screen I can see text along the following lines (its very small and quick to disappear):

 

unable to open rtc device (rtc0) 

 

I am really keen to get this going - any help appreciated!!

 

Cheers

What speed and size sd card are you using? 512MB RPi correct?

It's an 8GB Micro SD card.  it's the one I got with the Pi.  From my research of the marking on it, it looks to be a Samsung.  It's the one mentioned here: http://www.raspberrypi.org/buy-a-pi-get-an-8gb-noobs-sd-card-for-5/

Anyone have any ideas?  I went and got another SD card, Verbatim Class 10 Premium 8GB.  Exactly the same thing :(  :( :(

Can you provide more details explicitly on exactly everything you and doing and your setup?

I had a class 4 sd card and it was horrid.

How are you rendering the boot image of the SD card? Windows? Mac? GUI or command line?

Do all images of RasPlex fail to work? 9.9xx, 3.1, RC1, RC2? The latest is RC3.  When you mentioned you tried RC3, did you mean from stock image of RC3 or again from RC2 update to RC3?

You are on a 512mb Pi correct? How is the power source connected?

If you have tried multiple cards, seems like a HW/install issue.

Last I tried from the GUI installer on Mac only RC3 was only option list any longer.

Thanks for the help guys.  I figured this one out.  I read something on the website and on a hunch discovered the issue....  The below is what triggered it for me:

  • A USB micro power supply (should be at least 2A at 5v, if you experience crashing it’s probably because you have a bad power supply)

So it seems that the power supply I received with my Pi was rather weak, only 1A.  Grabbed my Galaxy S4 charger - 2A - whammo up she boots and works perfectly!

Now working and I'm loving it! 

Thanks again for your help.  :)
