HELP! Beagle Board xM booting problem...

Hi Everyone,

So i have this very odd problem with my Beagle Board xM. I'm using the
demo/SD card that comes with the beagle board kit.

It has issue where initially it restarts continually for about a
minute trying to do the same thing. After that it gets to a point
where it says it its done booting Linux and it starts restarting
again.Finally, maybe 5 min later is starting booting the kernel and it
get the to the point below. After that it just keep and restarting and
doing the same thing. It seems really wierd that without me doing
anything it keep on restarting a little bit more and then it gets to
the final point shown below.

Thanks for any help!

Dmitry

OUTPUT:

How are you powering the board? Via USB or the 5V plug? If its by USB, that’s known the cause various issues if it can’t supply enough power to the board.

-Michael

try using a power supply which can supply minimum 1A. And unplug any USB devices on the BB.

1 amp is borderline. Any PSU should really be capable of 2 amps or more.

I've had several of this sort of power supply that can no longer supply
its rated maximum current; so, if you /are/ already using an external
supply, try swapping it for another.

Dave

Thanks for the replay guys, I'm powering it by a 5V 2A Linsys power
adapter. I was hoping that would be enough, but I'll try another one
to see if it makes a difference.

Dmitry

Alright I have it all figured out. All it was is a power supply issue
as you guys had suggested. The power brick was providing 5.13 V which
i guess it too much for the system, which was causing it to reset at
random times. As soon as I switched to running it on a USB phone
charger it started working perfectly.

Thank you to all that replied to my question!
