Title: Help with powering Beaglebone Black using VDD 5V pins
Post by: mohak.bhardwaj on July 19, 2015, 11:15:52 PM
I am building a differential drive robot system and am using Beaglebone Black Rev C to run the software. I want to power my beaglebone using the VDD 5V (P9_05)and ground (P9_01). But upon connecting it to the power supply,  my board is not powering up and none of the LEDs ia blinking. Here are the specifications of the power circuit I am using:

Battery: 4.4V LiPo battery ib series with 3.7V LiIon battery(current limiting circuit removed for maximizing discharge rate)
Regulator: HTC LM2576-5.0 with rectifier (IN4007) and capacitors

The beaglebone makes a very light buzzung sound when connected to power but does not boot up. It is working fine when connected to my laptoo via usb. The voltage regulator output is coming out to 5-5.5V. Coyld anybody tell me what I should do to make this work?  Any help would be appreciated :)
