Dragon Board doesn't start


#1

Hi,
I recently bought a DragonBoard. I tried to start it up just a few days ago, using an appropriate power source, but the board doesn’t seem to do anything: no lights switch on at all.

I tried to wait, press the power button, hold the power button, buy another adapter, but nothing.

What should I do?

Best Regards,
Riccardo

Hi,
Thanks, but that’s what I’m already using. I tried 2 different ones with no success.

Hello, try to use a voltmeter and see if you power on these 2 pins 37 and 39. you should get around 4.95V

Alse the pin selectors on the back must be 0-0-0-0

Hi Skybax,
thanks. Unfortunately I get 0.0 V .

P.S. I tested the voltmeter and it works.


#7

Even if I measure on the pins just after the power jack, I still find 0V (of course if I try on the power source I get 9V if it’s set to 9V)


#8

With it plugged in to a power source ~12V @ 2A, bring up terminal on Debian. (I use ~14v)

dmesg -w

Plug in USB OTG port to the host / computer.

Any response in dmesg?

Try again with the - & or + button held down.

Sounds like a dead board. All the boot switches set to 0?

@r-cocetta

Do one last test add and power the board on the 36 and 38 pins and see if that helps.

Hi @Skybax,
I get 0.00V there too.

Hi @ramesh,
I think this doesn’t relate at all with my post.

My board doesn’t start at all, as in, not even the LEDs turn on.

@r-cocetta

Unfortunately it seems that you have a glorified paper weight
