Re: [beagleboard] HELP. dead beagleboneblack
Hi, The problem is the same after JTAG header soldered. But Power LED not lighting up while powered up through USB cable from laptop. Is my BBB dead?

JTAG header has two reset signals: nSRST (system reset) and nTRST (JTAG reset). I believe one of these two pins must be connected incorrectly. You might try to dis-soldered the header first and see whether the BBB can work then. 2014-03-24 1:52 GMT+08:00 dd ddlaw...@rocketmail.com javascript:: Hi. I bought BBB A6A new, 1 month ago.

Yes it does sound like it is dead. If the power LED does not come on, that indicates that it has an issue. I suggest you try getting an RMA. http://www.elinux.org/Beagleboard:BeagleBoneBlack#RMA_Support Gerald On Thu, Jul 24, 2014 at 4:29 AM, ksathish...@gmail.com wrote: Hi, The problem is the same after JTAG header soldered.

If Power LED still lights up, that means no short happens. JTAG header has two reset signals: nSRST (system reset) and nTRST (JTAG reset).
