Hikey Lemaker out of box

I purchased an Hikey Lemaker board with kirin620 SoC according to user manual:

I should be able to see debian/android boots up.
But from my HDMI monitor, I see nothing coming up after powering up the board.
What should I do?


After the board has booted the User0 LED should be heartbeating about once per second, is it something you observe ?

Could you check the jumper configuration (J15), documentation says:
Auto Power up Link 1-2 closed
Boot Select Link 3-4 open
GPIO3-1 Link 5-6 open

I suggest you to read the Hikey monitor documentation as well.
