Board Does Not Power On, Power LED Flashes Once

I’ve managed to damage BBB when I was disconnecting power input cable from it.

Is the following issue of old Beaglebone still valid for the BBB?

Just wondering, I might have damaged it because it was connected to another device via I2C bus, but there was just 10kOhm pull up, so it seems not very probable.

Thanks.

You really need to power down the board and not pull out the power.

Whatever the cause, the board needs to be repaired.

By powering down you mean either:

  • issuing power off sequence from the OS
  • holding power button for 8 seconds

Or is it also good enough just disconnecting power supply from wall outlet?

Thanks.

You should be able to just press the power button once briefly and it shutdown. Assuming the image you are running has it. The latest image does have it.

After it powers down, then you can remove the power. We need to make sure the PMIC powers down all the rails to the processor in order.

OK, thanks.

You might consider adding this information into the manual.

Or you can enter “halt” on the console or terminal window and it will power off.

I will add it to the manual. But then again, I just decided this today, so I would appreciate giving me a little time to get it in there.

Gerald

Done.

Yes, I see it in the C.1 doc. It could be more imperative than just recomendation, but it is there. Thanks for fast action.

Non imperative was the idea.
