what do I do worng?

Our two most common types of failure are either power supply or SD card related.

Crappy SD cards (fake or substandard) or bad image burns account for about 60% of Pine board failures;  the rest can usually be accounted for due to crappy or under-volt power supplies.

We recommend Samsung Evo Plus Class 10 32G cards.  Use a power supply of 5v @ 2500ma  2.5A and if possible power the board via the euler bus pin(4  +5v)  and pin(6  ground).  ( the micro usb connector is substandard and will not provide stable voltage|current particularly during boot.

Get yourself a serial to usb ttl bridge adapter cable.  This will allow you to monitor the serial console during bootup which will help you diagnose what is happening;  usually the Pine board is in fact booting, but the hdmi is not working for some reason ; usually due to monitor specs, etc.

Also, notice whether the LED(s) are blinking on the eth jack;  do you see it attach on your router ?  You can ssh to it if so!
