Yeesh, that page needs updating... Angstrom hasn't been "default" for
what, 6 years? And the R-Pi likely has 1+GHz & 1GB RAM these days.

Powering straight off PSU. I'm using mine for pixel lights for christmas

Re: [beagleboard] Re: PocketBeagle fragile?

2021-01-16 Thread jonnymo 
Just out of curiosity since I have a PB as well, how are you powering the
board?
Are you plugging straight into a PC USB port or via a Powered USB Hub?
Is a case or carrier board being used?
Are there any external components connected to the PB GPIOs or other
interfaces?

The environment the board is being used in might be of consideration, such
as carpet or solid floor like hardwood. I would suspect the PB is quite
susceptible to ESD issues.

Cheers,

Jon

Did you disconnect ALL peripherals before removing the main power
supply? If you didn't, and any peripheral still had a charge feeding back
to the Beagle, you likely killed at least a few GPIO buffers, if not more.

This really isnt any help but I started setting one up last week as I am 
going to get into the christmas displays next year. In FPP I shut mine down 
before removing power. Yesterday I connected everything again and NOTHING, 
single blue flash when i connect to PSU or to the USB port.. So yes, same 
thing happened to me and I didnt do anything.
