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 is 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 increasing 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 laptop via usb. The voltage regulator output is coming out to 5-5.5V. I found other topics where people faced similar problems but none of them answered the question conclusively. I have an amateur level knowledge of electronics and really need to get over this hurdle in order to get my project running. Thanks in advance!
