Hi up-board staff
I am testing the realsense driver on the board.
After i install ubuntu 14.04.5 on the board(installation process is perfect), the OS does not load correctly.
the blue LED light up as i press the power button, but after that the screen flash some loading screen in a few seconds and then nothing happened. screen go dark and blue light went off.
What is the possible cause of this problem? power supply shortage? board is broken? or something i miss? Hope i can get help ASAP.
After speed so much time and money on this, i hope the board is worth it.


thanks
Steve

solved, it is caused by DC power supply.
