2 out of 3 boards defective

Nothing to forget when flashing the eMMC in this case really . . . Also, the error he is showing is not exclusive to him only. rsync timing out after 60 seconds.

So these are not BeagleBoard.org boards and are not covered by our warranty. If you feel you need them replaced, you need to contact the folks at Element14 about their product…

Richard, to set you straight a bit
the power supply can supply up to 100 amps.
it does not matter how much current the supply can supply
the beagle will draw up to 1 amp if you are flashing the Emmc
the beagle runs fine on the 500ma USB power supplies as long as you are
not flashing the emmc.

these are known to work well with the BBB there are countless others out
there
i personally use a 5v 700ma phone charger on one i have plugged into the
USB port
and a 1a one i had shipped over 2 years ago from china for 3 dollars
free shipping on another.

if you plan on loading up with capes you will need even more current.

pardon me if i misunderstood your email. but a 2amp wall wart is just fine

I have used a few beaglebone black boards and they were all perfect.

You jump to conclusions too quickly.

We have used many dozens here with never a problem. All “official” Beagles, not Element 14 or other clones, it that matters.
