Hi,
my beaglebone black developped an unwanted behaviour:
When powered it wont boot. It only boots, after I have
pressed the reset button on the pcb.
I tried this with the original image of the onboard
eMMC, which is still there untouched from the beginning.
Is there anything I can do to fix that?
Thank you very much for any help in advance!
Best regards.

What is your power source?
Gerald
Hi Gerald,
its a 2Ampere Switching device, which works over half an year now with
my setup…

Are plugging in the DC connector to the board or plugging in the power supply withe DC connector already plugged in to the board?
Gerald
Hi Gerald,
I first plug the power supply into the wall mains adapater and then the DC plug into the Beaglebone Black (A5C, by the way).

Hi Gerald,
I am living in Germany...
The main question is: How long will it take and how much will it cost?
Rough estimation?

Depending on where you bought it, you can return it to where you purchased it for a replacement after the RMA is approved.

I bought it from www.exp-tech.de.
Currently -- as so many others -- they cannot sell
any Beaglebone Black...everything is out of stock.
Sigh...

Well, they are supposed to have RMA stock and not sell that stock. If they have no RMA stock, maybe they don’t get to be a distributor anymore. Go ahead and request the RMA.

Oh, I didn't know that! Ok, thanks for the help! 
Have a nice weekend!
Best regards,

Hi Gerald,
believe me or not
...but...
MY BEAGLEBONE BLACK IS WORKING AGAIN!
I didn't change anything. The only thing I can
think of is a massive RF noise on the mains from
a HAM in the neighbourhood or from a "crazy" (badly shielded)
electrical tool/machine/something here in the apartment building...
its an building from 1900, so the power line may be not as good
(in concern to RF/noise/spikes etc.) as elsewhere.
Miracle or not...I am happy. Weekend saved! 
Again, thank you very much for you help in hard times :))))
Best regards,
Meino
