I have been successfully using BBB powered from the USB adapter until now.
I had to do some restart, and then the board won't power up (the
PWR led blinks once when I press the
POWER button, then it stays like that, off).
Now I can only start the board using an external power supply (
5.0V), and it seems that the board uses around ~
0.8A and up to ~
What can be wrong?
Why it isn't working now?
L.E. Also, I have noticed that the main chip (
AM355) gets very hot, I can't put my finger more than one second on it.
L.E.2. I don't have attached any relevant power-consuming devices to it, only a USB WiFi dongle.
L.E.3. Before restarting the board, I was trying to get a
GPIO pin working, the problem was that from the library I've used (
BlackLib) when I set one
GPIO pin to
high, it would only stay
high for around
10ms, and then go
low again. So for solving what, I have used this tutorial. I only got to the part where I exported some pins to the /sys/class/gpio/export file, and then echoing
0s to the associated pin (with a LED connected it didn't work), then I rebooted the board and this problem started.
I don't see any hardware mistakes that I may have done, is it possible that this fault is software-related?
