Can not get board to boot up reliably
update: I just did some quick measurements on the euler power pins while powering the Pine with the standard micro usb power supply delivered through Pine online shop.
I did measurements with a scope and did not find any power issues. Keep in mind it was only on the euler power pins so depending on the board layout some ic's could still have power problems due to wrong capacitance or inductance on traces. I saw a max. voltage ripple of 200mV. I also did a sysbench to max. out the cpu usage and saw a max. voltage drop of 300mV. Voltage measured on the euler 5Volt pins at idle : 5.2Volt average.

If needed i can do extra tests. Like voltage ramp up patterns to see if the unit has problems with it. For now i am happy with it.
