The dragonboard I was using seemed to be working fine for a few days. During a normal operation, suddenly the BT LED started flashing blue, and the board stopped being discovered in Wifi network as well as in the adb or fastboot over USB. Now as soon as I plug the board to power it starts overheating and only the blue LED is on. I tried resetting and flipping the SDCard boot switch and booting the OS from an SDCard, but it didnt work. Its almost like the board is dead except the LED and overheating.
Can you please let me know what might be the issue?
