BPI-M2+EDU / nothing on debug UART


When I power up the board there is a constant voltage on the RX/TX pins. Only the power LED is red. The HDMI output has no signal. The ETH is not detected by my switch.

The android image does not change anything.

But pressing the reset button decreases the input current a little bit.

What am I doing wrong? It’s my first day with such a board… :slight_smile:


Bye Arne


it’s me again… :slight_smile:

with ArchLinux image and a power cycle the UART shows the output that i’m used to from my big box…
