Hi, there, I also have the power problem in my two Beaglebone black, Rev C. One of my BBB totally die out and no any led turn on when the power was plugged in no matter from usb or DC jack. The other one just have the power led flashing once.
I have disabled the HDMI in Env.txt and use six pins for receiving three DC motor decoder signals, use three pins to output PWM signal and three pins for direction control for three DC motor. So far, I still couldn't find the reasons that make them broke even I carefully read the user manual. I also use flyport with pic24 for flying control for more than one year and that board is very stable and never give me any headache. The BBB designer or manufacturer should came out to give us a good explanation because so many people have same power problem.
