Re: [beagleboard] Power failur .
Sounds like you may have broken it. How are you powering the board? What was the last thing you were ding with the board?

Re: [beagleboard] Power failur .
i did connect rs232 to serial converter to this board . . . connect ground with p9.1 , rx pin to p9.24 and tx pin to p9.26 . . . I did configure UART-1 in my beaglebone . but it work perfectly. after i connected rs232 the board could not power up. . . *-- AK SARATH* On Thu, Dec 4, 2014 at 12:49 AM, Gerald Coley ger...@beagleboard.org wrote: Sounds like you may have broken it.
