And use the serial console from the EXP header pins (since then they can't backpower the board which leads to all sorts of strange behaviour and might be related to the problem you're running into)

The debug board is only connected to the Euler connector via GND, TX and RX, the board is powered via the micro USB port.
There's also jumper for DC5V/BAT

Ok, so you've a 2GB board. The jumper is to provide USB peripherals either with power from DC-IN or through the PMU.

I asked you to do it differently. Smile

Use jumper wires and connect 5V/GND to pins 4/6 on the Euler connector. And use not the Euler connector for serial console but the EXP connector next to it. If you look into their Wiki you will neither find Euler nor EXP since they call the connectors Eular and Ext instead (for reasons absolutely unknown to me): http://wiki.pine64.org/index.php/Main_Pa...nformation
