BBB shutting off by itself

[stanward]

Hello,

I have a BBB hooked up to 6 P10 panels.  Everything between xLights and the BBB/P10 works fine.  Randomly, the BBB will just shut off, usually after a few minutes of being powered up.

Sometimes the BBB will shut off even when there is nothing being displayed on the P10 panels.  I hooked up my oscilloscope to the 5V power supply and don't notice any noise or voltage dips (unable to capture the point where the BBB shuts off).

I am powering the BBB through the barrel connector, I previously was powering it through the Cape with the same problem.  I am using the 5V power supply from DIYLEDexpress (came as a bundle).

I updated FPP from v 1.5 to v 1.8 thinking that would fix the problem, but it didn't.

Didn't your earlier post make a pretty conclusive decision about the 5vdc power supply?

I have another question, why does the 5v power supply (DIYLEDEXPRESS) cause the BBB to just randomly shut off?

If I feed 5v from my bench power supply, the BBB runs fine.

I am feeding 5v to the terminal block on the Octoscroller Cape.

I couldn't find anything wrong with the o scope.  Thought the cheap pwr supply would've been noisy.

I was wrong!  I left the BBB running off of my BK Precision Linear Regulated power supply (at 5.0Vdc) and the BBB shuts itself off,  Nothing was connected to the BBB, other than the SD card and the USB thumb drive (that is empty).

PS, I am powering the BBB through the barrel connector.

Can anyone please help me?

I did more testing tonight.

It turns out if I plug in the micro SD card containing FPP in it, the BBB will randomly shut off.  I ran the BBB for an hour without shutting off (without the micro SD card plugged in).

Here is the debug/flash-eMMC.log if anyone can help me:

There are multiple file access errors in your logs.

If you have another class 10 SD card handy, do a fresh install of FPP.

Thank you, will try that!

Hello JonB,

I just found out I made a terrible mistake.  I setup my P10 matrix using the eMMC method and not the SD method.  But I left the SD card in the BBB as well as a USB flash drive too.

The 16GB SD card was only formatted to have 96MB of space, where the other 15.xGB space is unallocated.  I think this is the reason why the BBB would just shut off.  I am unable to delete the partitions on this SD card to create one large 16GB partition.

Is anyone able to help me with this SD card problem?  I am in Disk Management, but unable to modify the partitions.

[rlemery]

Have you tried reformatting the SD card  using the SD card format tool from the SD card association?   I know that fpp will put files in the card In  Linux and Windows cannot read it.

The Drive Management software that comes with Windows 10 doesn't see or show all the partitions on a Debian partitioning.
There may be third party software that will handle it. My solution has always be "scorched earth" when an SD card acts funny. I just use the SD Formatter utility mentioned in the install instructions, and wipe the SD completely.

I've found it easier to start over from a fresh download than to spend hours troubleshooting. That's just me.

Yes, agreed, to start with a fresh install.

I did just that, a fresh install with another SD card and while I had the P10 matrix running for a few hours, I was trying to troubleshoot the SD card.

I will download the utility.


Thank you!!
