BeagleBone(White) - PWR LED Blinks Once - USB Power - Works fine with Power adapter

Asked by 5 months ago
Hi Guys , I have a beagle bone , when i connect my USB cable with BB , It blinks PWR Led once and nothing happens, but if i connect it to DC 5V Adapter, it works fine but i done get the USB to Ethernet interface. I have tried formatting SD card and also replacing the cable, Also, the 5V Adapter supply which i am giving is also from laptop USB, so i dont know what is wrong, Is it a problem with the H/W, i.e. FTDI IC or something Else, any help will be greatly appreciated . Thanking You, Gurinder Singh Gill

Are you saying you have a USB -> DC Jack type plug? Have you tried a different computer?

Yup USB -> DC type. and yes I Have, but same as ever, also I own an Beagle bone black , thats works absolutely fine . I have eliminated the FDI chip going bad , as in LINUX when i connect the Beagle Bone(White) it shows connecting as FTDI for a sec, and goes off .

Sounds like the board is damaged. I suggest that you request an RMA. Gerald On Thu, Nov 28, 2013 at 11:02 PM, Gurinder Singh Gill

thanks for the tip Gerald but what exactly is a RMA ? and if BB is damaged why can i still boot Linux using DC 5v Power supply ? Regards, Gurinder

Returned Material Authorization. It is when you send the board in to be repaired for a Hardware issue. You request one, we send it, and then you send the board back. You said the power LED blinks once. Is that not a true statement? *" I have a beagle bone , when i connect my USB cable with BB , It blinks PWR Led once and nothing happens, "* Gerald
